The M152 starts AMG future trends Analysis of the the AMG brand-new 5.5L V8 engine

Mercedes - AMG has developed a new 5.5-liter V8 engine: has strong power 8-cylinder machine at the same time does not meet the performance and fuel consumption of the logic of the four-cylinder machines. Has been able to achieve unparalleled efficiency thanks to the AMG engine exclusively developed closed cylinder system. This powerful eight-cylinder machine like an F1 car engine as a thunderbolt, and the new invention closed cylinder system is mainly used in fuel savings. Compared the existing AMG5.5 liter V8 engine, the new engine saves the entire 30% of the fuel, this high-speed naturally aspirated engine in show AMG outstanding innovation capability and also to show people the naturally aspirated eight-cylinder engine. the potential for energy saving.
This has the unique AMG engine management system and direct injection technology 5.5 liters V8 engine codenamed M152, temporarily will only be used on the new 2012 models SLK55AMG (R172), used to celebrate it in September next year, the Frankfurt International Auto Show world premiere. The which means SLK55AMG still is a the hardtop roadster field only eight-cylinder engine of the car. The peak output increased by 60 horsepower to 415 horsepower the Mitty rose to 539 Nm torque from 509 cattle, 30% less fuel consumption and performance, these will be placed on top of the competitive market segments SLK55AMG. The SLK AMG Group youngest head, used for the test of the new engine is indeed a good choice - is the cylinder management and lightweight design, the horsepower the amount is not important in the early development of the core concept of the M152.
The new M152 is based on the starter MY 2011 CL63AMG and S63AMG M157 5.5-liter V8 twin-turbo engine development. Between many systems and components are basically the same, such as displacement, bore stroke ratio, cylinder distance, ECO start / stop system and direct injection technology. M157 special including the new intake pipe, the new cylinder cover, the improved valve driving assembly, an adaptation of the fuel supply system of the system of the closing cylinder and through the crankcase to reduce friction optimization.
"With the new 415-horsepower AMG5.5 liter V8 engine, we once again created a true artistic masterpiece. M152 is an outstanding example to improve the efficiency, and at the same time show the creativity and experience of our engineers, they have developed a closed cylinder system inspiration from Formula One racing to get this new naturally aspirated engine makes the perfect power unit at the Frankfurt International Motor Show in autumn to celebrate the premiere of the new SLK55 AMG Mercedes AMG main Xiao La - Karen Vilnius high hopes for this new engine, I believe that with the success of this pair of engine, closed cylinder technology which will be extended to the AMG series engine.

Honda Ma hippocampus Familia DC approach in mind I

Before the opening of the first to explain the approach into the stadium. "Racing", I believe that if you have paid attention to the race, should know that it is very different from our ordinary street car. Say most top international venues events that F1 is beyond doubt, but if most top touring car thing? That should be able to be regarded as the WTCC. In fact, in addition to a number of international competitions, our domestic many venues events, but also to the majority of Touring Car, large national level to the regional level (such as the Pan Delta Super Racing Festival, Tianma driving, etc.) have . The national championships are basically some depot or has the economic strength of the private club participants the geographical level events is based on the converted stores the name of the competition.

Have introduced many venue racing on our website, but basically have some finished models, that is already is able to participate directly in the game, but we have not thought about a racing out how to make it? When a car began to change first of all you want to do? The second step have to do? I believe that in addition to the ability converted stores, few people know it. No hurry, Next, we have to bring everyone together, episode by episode introduced in the end is how the birth of a venue racing. That so many seem to also did not say this car is a car? In fact, the protagonist is a hippocampus Familia. Do not despair, it is not ordinary Familia so simple, I have said in the title, it is called the Honda Ma, why so called? Because it falls into the from Honda Integra (DC5) Type R the red roof heart K20A. Well, then do not say, below we illustrate with pictures.





Figure: The first step in making racing is everything removed, then fired body repair welding and roll cage, welding, because the original car the solder joints are generally not too, because of the need to staylittle activity space, maintain comfort. As for firing the roll cage, in fact, has two purposes, the first is to protect the safety of the riders, can serve to strengthen the role of the frame rigidity.



Figure: Because of the time, the frame has been removed empty roll cage as well as welding and has also been well.



Figure: the space of the engine compartment is quite large enough to accommodate under K20A but how put something? The next time decomposition, but it can be said, the engine compartment below the root metal framework, it is used to support the K20A.

Four-wheel drive technology Mitsubishi S-AWC chapter

The beginning of the 21st century in the late 1990s, I believe that filed Mitsubishi, a little bit of automotive common sense first reaction will be the Pajero. Indeed, Mitsubishi started by the military do four-wheel drive in this area has its unique advantage. Whether in politics, for the understanding of all levels of Government, business, people, most of the first choice to buy a sport utility vehicle will be the Pajero. Even the TV inside often Pajero been through the worst of the road, the first time to reach the scene of disaster relief scenes. Many people put to Pajero included in their own Dream car, visible Mitsubishi Pajero name deeply affect our Chinese generation 70,80. But Xiaobian latest issue of four-wheel drive technology protagonist is Mitsubishi's another classic pull chariots - Mitsubishi Evolution. Good or bad decision in the four-wheel-drive system in the pulling force on the battlefield for the record, that rule the roost in the WRC Evolution-wheel-drive system S-AWC What is unique about it? See below.




AYC,ACD,ASC,ABS共同组成三菱S-AWC(超级全轮控制超级控制系统,其中AYC,ACDS-AWC里的核心组成部分。


Photograph: ACD active differential
ACD ( Active Center Differential ) is the active center differential English abbreviations, first appeared in the great change of Evolution VII. The role of ACD is through a limited slip differential control of front and rear wheel power output, limited slip differential consists of electronic control hydraulic multi-plate clutch. Active center differential can timely control of differential slip force, to ensure maximum traction force and will not affect steering. Moving in a straight line, owing to the front and rear wheel speed difference is almost the same, ACD is a release state, ensure that the vehicle acceleration, braking stability; curves, differential moderate locking, increase the steering response. ACD according to the speed, the steering angle, steering speed by the electronic control to ensure optimum traction and steering response; when needing to lock the anteroposterior axis of time, ACD binding. This is connected with the central differential two conical gear housing shaft combined, that is to say, two conical gear rigid connection, before and after the shaft will no longer generate rotational speed difference, before and after the shaft power is 50:50 distribution, and in order to overcome the bad road resistance. Because Evolution uses is the transverse engine layout, the differential arrangement using a unique design: 1 used a shell shaft technology and hydraulic clutch for front and rear axle differential lock; 2 front differential and center differential in coaxial position and with the engine crankshaft parallel; 3 on the front and rear axle differential the lock is through to the two casing shaft locking implementation.
YC ( Active Yaw Control system ) is the active deflection control system of English abbreviations, the system first appeared in 1996 four generation Lancer Evolution. Now the S-AWC integration is the improved super active deflection control of Super AYC. Super AYC appeared in 2001 ( Evolution VII ), can make the two rear wheel torque output, according to actual needs of torque output, to meet the demand on the body of the deflection control. The technology of the highest state is 4 wheels provide a corresponding torque.
When the need to take power from the left half shaft passes to the right half shaft when, the green clutch. The power through the purple rear axle differential gear casing passes to blue, is passed to the green shell axis, finally delivered to the right half shaft. When the need to take power from the right half shaft passes to the left half axis at the time, red clutch. The power through the right half shaft transmission to red clutch drives the shell axis, through the blue to purple gear transmission differential casing, finally transferred to the left half shaft. For example, when oversteering, will give the inner wheel torque makes more oversteer condition reduce understeer; similarly, to the outside wheels provide a little more torque.
As for the other two equipment -- ASC and ABS, ABS do not have introduced it, anti-lock braking system is a perfectly normal automotive equipment. ASC also is not what new product, and ESP electronic stability system 's name is different, the function does not exist big difference.

Hybrid two forms: strong mixed weak mixed dispute





The lack of oil resources gradually, according to the authoritative survey shows that the development of current petroleum consumption status quo continues, will be held 54 years after the consumption of the world's oil resources exhausted. So, who dream thinking about fuel prices decline, wake up, it is impossible. Although the reality is so cruel, but the scientists are in the process of seeking energy new breakthroughs, developed the use of non-fossil energy car. Such as the U.S. Ford Motor Company in 1958 developed a concept car called the "Nucleon", for the energy-driven nuclear fission of uranium elements, added a uranium allows Nucleon traveling 8000 kilometers, but in the end due to a variety of factors And no amount of production.



Figure: "uranium-energy the Ford Nucleon nuclear-powered concept car

In addition to the Ford Nucleon outside, Cadillac also released in 2009, a nuclear-powered concept car - WTF, design life of 100 years! The WTF also exist only in the drawings, but we have to admire the American automobile manufacturers thinking ahead.



Figure: exist in the design drawings Cadillac WTF concept car

Since the powerful nuclear energy in the first stage of civilization of mankind can not be completely under control, we still realistic, look at the results achieved in other energy fields. In fact, as early as 1873, the Englishman Robert Davidson (Robert Davidson) produced one of the world's first electric vehicles available. This gasoline engine car 13 years earlier than the German Daimler (Gottlieb Daimler) and Benz (Karl Benz) invention. In 1899, the French the test doors Gina driving a dual motor powered electric vehicles, create a speed of 106km record. Seen the development of electric vehicles in history is not lost to fuel cars, what factors to its development and large-scale application do? The answer is simple, due to technical constraints, resulting in electric car production, use, and maintenance costs are high, are secondary energy is energy, and energy storage are also technical bottleneck exists, therefore, now car or fuel for the majority of the energy.
 

 

Fiat variable valve control system Multiair





Variable valve control system, such as the Valvematic Honda VTEC, Toyota, Nissan the VVEL and BMW Valvetronic and needed continuous transformation valve lift. Addition to the continuously variable cam phase, they seem to have very advanced. But the distance of the word "perfect" there is a very long distance. The ideal variable technology should be unrestricted and flexible transform valve lift, in other words, that is, at any time, there should be corresponding to the valve lift so as to achieve the desired combustion. Nowadays any mechanical system is not able to achieve this level of function. Some developers try to develop electromagnetic valve structure, but also facing some technical problems, such as the size and weight of the institutional problems, cost, reliability, and fuel consumption.

But entered the 1990s as a VVT pioneer Fiat sees traditional mechanical structure VVT lack of mobility and responsiveness, the research focus to a more flexible and accurate control of electro-hydraulic control system. After overcoming many difficulties, the 2009 Geneva Motor Show, Fiat officially released its variable valve technology research: Multiair electro-hydraulic intake system. Their assembly the 1.4 FIRE series engine and the subsequent occurrence the 900CC-cylinder engine.




There is no doubt, MultiAir is the most flexible and accurate VVT system. Multiair electrically controlled hydraulic intake system structure corresponding to the different load state design for the five kinds of conditions, in addition to the length of the basic open time, the head outside the low transition, it can in the intake stroke in the valve opening time adjustment.

Analysis of traditional DOHC Engine Valve DOHC VVT diagram we all know, the ordinary engine valve train driven by a cam on the camshaft, valve to open and close the mechanical rhythm, the accelerator pedal by the intake manifold a throttle valve to adjust the flow rate of air. For engine valve timing and lift technology, the size of the valve opening (stroke), the timing (timing) can be determined by the camshaft and control mechanism.

MultiAir the biggest feature is pioneering the use of electronically controlled hydraulic control system to drive the valve timing and lift, it is driven by the camshaft through a set of electromagnetic hydraulic valve, stepless adjustable intake valve lift and timing , though still is a structure of four valves per cylinder, but abolished the side of the intake valve camshaft, and retain only the side of the exhaust valve camshaft to drive intake and exhaust valves. Since the valve opening degree and opening time are arbitrary adjustable, so the system and BMW Valvetronic can be directly closed by the valve opening size to control the flow rate of air therefore also canceled throttle. Exhaust valve camshaft directly promote the intake valve through a set of solenoid hydraulic system for precise control.

To direct injection + dual-clutch: New Fox dynamical systems

Changan Ford's new Focus power system will usher in a comprehensive update, the combination of direct injection engine with dual-clutch gearbox new Fox will become the largest selling point.

New Focus is equipped with a naturally aspirated 2.0-liter GDI direct-injection engine with Ti-VCT variable timing system, non-turbocharged engines for Ford in China, launched the first application of direct fuel injection technology. Fuel injection technology allows the cylinder can suck more air in each work cycle, high pressure fuel Zeyi 200Bar them directly injected into the cylinder, so as to get a better atomization. With the high compression ratio settings, engine performance and economy both benefit. Depot introduction, this pair of engine output to 170, 100 km combined consumption of 6.8 liters.





New Fox used PowerShift 6-speed dual-clutch gearbox with dry clutch piece design, beneficial to its sensitivity, and to reduce the running resistance of the gearbox. Match more closely the gear ratio setting that can further enhance the new Fox speed performance and power bridging.
 

The new Fox corners Torque intelligent distribution system

Automobile differential understanding of friends will know the general differential characteristics of delivering more power to the resistance of the smaller side of the wheel, which would cause a problem - transferred to the outside due to the weight of the vehicle when corneringside, the outside wheel resistance increases reduce the inside, then the differential will transfer more power to the inside wheel. In this way, itself caught fertility decline in the inside of the wheel easy to slip the outside wheel is not the driving force, so that the vehicle can not be smoothly out of the corners.

So, some high-performance cars or modified cars will be installed mechanical limited slip differential (LSD), in order to prevent this from happening, and the new Fox braking system to simulate the effects of LSD. "Bend torque intelligent distribution system integrated in the vehicle stability system which, when the system detects when the inner side of the vehicle slipping interested wheel a little braking force is applied, so that the inside wheel resistance increases, so that the differential momentum transported to the outer wheels grip more and more, to help vehicle faster out of the corners. Such systems is not a new thing, but it is a major breakthrough in the Fox this level models in use.

Cross Kai is best to have a short to the demolition of the panel above the screws.......

I belong to the type of obsessive-compulsive disorder, keep the car clean, the appearance is not vague, with more than a month Taobao buy double tail jets, couldn't help! For a long time about Excelle modified exhaust homework, but changed little, so get the idea to give up, but the spirit of 20 in this age, no longer toss toss or later will not have the opportunity is not it, therefore, do two continuous, for Beijing Xiguomao an entity shop converted, the original position of vehicle exhaust less S drums, but there is some, but I still want to install double tail throat, single tail throat is not installed, but all S drum caudal laryngeal behind are 1 kind of 2, not two the exhaust pipe, so the feeling on the vision with me before the caudal laryngeal installed do not have what distinction, and S drum sound, a bit disturbing, high-speed easy a resonance, heard this common problem, so decisively abandoned S M drum drum, original a price is much expensive, but also not a big brand, is the main... Double is really too small, then the boss recommended me for a fox tail drum head, said in Italy imports of stainless steel, assembled in Taiwan, the price is high, is the M drum sound, than the original car a little bit, but is a welding, but the boss take money, I will I feel this good, this is the double tube out of work, and looked very good, I actually do not need any power ah ah sound, pure as good-looking, want to go HF fan does not change the exhaust line, the final decision, open solder! Here and look over the narrative process.
Go when no other car, directly on the shelf!
Car hanging up, this point of view is really a SUV ah, after finished, I found a screwdriver buckle wheel stone
Exhaust factory, at work is quite good, with the more trouble, but the store so much idle people not white do not not

The technical difficulty little 1.6 manual Excelle modified automatically controlled air-conditioning

Manually KK1.6 two years, the performance has been good, average fuel consumption of 8.5 basic run urban, the LP adult just started to get turned around 12, see the silver shining white stop the outflow of my heart panic .... Closer to home, I have this hobby (amateur self-study), the practical ability can also dare car demolished demolition, two cars, maintenance is also good.

KK's good air conditioning performance the cooling effect personal feeling is very good, but that manual control over long distances uncomfortable, not off AC, cold off while hot. Thus kept open, shut, open, shut ..... really irritated. So would like to change the idea of automatic control. Online search, turn over, but other models, KK rarely, but also the old models. Wanted to come to the same principles, the technical difficulty is not large, so determined to hands-KK, manual air conditioning change.

Online spend 85 rice, bought a miniature electronic thermostat, the day before 6:00 PM start, huh, huh, too hot during the day, can not stand, only sunlight, slightly down a little cooler.

Thermostat wiring


Special note: made ​​a positive line at hand is not enough, so the red line made ​​negative, the yellow line. No. 1: negative (casually ride in the metal of the vehicle body on the can); turned No. 2 and No. 4, as a positive electrode (the AC signal input terminal); No. 3 for the output terminal of the AC signal by the thermostat control. Line is the best is a little rough, some insurance, afraid that the current is too large. No. 11, No. 12, then the two wires of the sensor head (random access, regardless of positive or negative).

Second, the dissolution of the panel, the co-pilot before the tool box. How demolition method do not speak more online. I first demolition panel, had a lot of fresh. Talk a little experience: go to the hardware store to spend 2.5 yuan to buy a lacquerer scraping gray scraper (narrow point, this is 5cm wide) demolition panel lingua franca (Note To cushion layer of paper on both sides of the blade yo do not directly use the scraper to ski, easy to scratch the panel). Demolition from the start that the cover of the mesa, and the front windshield at the start that gap, skid-up hand up pull got on the cover all the clips, a little tight, likely will clamp tension, but the relationship is not . Online stresses on the seams of the cover from the panel and began to pry, that is wrong, would damage the cover, I began to eat a little loss. Finally, by observing only to find the front windshield at that the seam began fishes head. The cover apart, you will see two screws at the top of the control panel, unscrew the screws, they rely on the Arts daring effort (all clips), have to cautious, do not get to spend the panel and the surrounding decorative epidermis.

Panel pry open, do not rush to win actually Nabuxialai. Under three knobs, each of the two knobs on the right (outlet conversion and cooling and thermal conversion) internal one PULL since even with the other components, respectively, head stretched down under the direction of the machine and tool box to see the demolition The method is also very simple, not much mentioned, can also find online diagram look at the. Pulled out the wiring on the control panel (rest assured dial it, the bayonet is a one-to-one correspondence), my electronic clock line is too tight, but also no reversal, no matter what.

The demolished panel spent more than two hours, sweating. (I use the tool, originally computer repair, to fix the car, compiled computer program can also find me ...)





Cross Kai is best to have a short to the demolition of the panel above the screws.
