Do you know how to properly modified Mb Star C3 and used brake it?

Why cause brake problems?

1, brake master cylinder flow:
If only increase each wheel brake cylinder (brake calipers), increase
Mb Star C3  piston brake pads Wheel Cylinder promote more and more, more brake oil supply unit of time is required, but our users do not replace the brake master cylinder, master cylinder oil supply original slave cylinder design, can not supply enough new slave cylinder oil.
Example, the original brake master cylinder per second in full braking state a total of brake fluid to the wheel cylinder is 220ml, and it matches the original single-piston brake wheel cylinders, if I switched to AP 6 piston brakes Wheel Cylinder, per second need to inject 400ml brake fluid in order to achieve the maximum brake force, at this time, our blood supply inadequate, brake wheel cylinder naturally unable to fully promote full friction brake pads master cylinder, and perhaps you side step the full system action, but Wheel Cylinder oil supply shortage, only to achieve a 60% intensity.

2, is not fully open skin
Change the size of the brake discs, polished
BMW OPS DIS V57  brake disc surface, brake disc surface uneven cause the steering wheel when the brakes jitter. This situation did not start running-is hard to find, and low speed state, because obvious so undetectable. In fact, does not affect the braking effect, but a long time bad brake pads, re-sanding is necessary.
Brakes just installed, in addition to the time of commissioning, the master will conduct the initial run-in. Fully run-in, but also take some time, at least a few hundred kilometers, before that it is best not kind to activate the ABS brakes.

3, error and maintenance methods: brake disc temperature is very high for a long time to run high-speed or intense driving. Some owners found the car eager to water to help cool the brake discs. In fact, such an approach
VAS 5054A  is tantamount to Yamiaozhuchang brake discs. Metal brake discs under high temperature forced hot and cold exchange will result in the metal increased brittleness, brakes prone to deformation or cracking, and seriously affect the braking effect. Watering to the brake discs is definitely worth the candle, this unscientific ah!

Ford vcm ids Focus Sony audio system

Car life, invariably accompanied by around music, new  ford vcm ids listing of 2012 Ford Focus models equipped with nine speakers speaker system in the control panel, printed electronics giant - Sony logo, which undoubtedly raise a lot of "fighting" the new Fox. Next, small series will disassemble set the acclaimed of Sony multimedia entertainment system.
Before dismantling, small audition to set audio. Overall, the quality of the sound is still worthy of this living symbol of the signs of the "Sony", hard to find opponents at the same level in the car, and a better interpretation of the popular music, which is also in line with the Fox vehicle positioning - young The family retained the usual style of Sony coloration.
Having said that, listen or be able to discover the inadequacies of the sound system, lack of low-frequency elastic; IF Fortunately, the vocal is full, but the accuracy is poor; relatively weak high-frequency. Under 9 speaker 
opcom op com surround system, the sound field position proved to be less Another resolving power also needs to be improved.

Above the center console, the screen size is small, but able to need to know the information is clearly displayed, and UI design is very gorgeous, and no sense of catching operation. Sound performance is clearly optimized for pop songs, average low in high-frequency performance, while the thrust of the original amp is not very adequate, in the case of fully open volume, the distortion of the sound is not very obvious, especially the low-frequency The amount is still very adequate, but dive depth has to be raised, can be improved by the installation of a subwoofer; IF is almost the same, the sound reduction more accurate, but the vocal performance slightly inferior; Finally, high-frequency The performance is more general, but much better compared with its class.

Apollo LDK vehicle height adjustable obd2 usb shock package

The Apollo the LDK shock package installed the trial  obd2 usb SAE9254 the Japanese alloy silicon chromium steel made​​, in order to provide better durability, which uses the outer diameter of 52mm Flashlight, short stroke Duantong core design and the original Japanese imports piston. In addition, it also has a "full speed domain ultrafine low-speed valve" design in low speed, more comfortable. View of the installation of the shock is not just casually split in a loaded will be able to leave Cleveland, and if so human error in the installation process, ranging from the impact of the shock performance, while cause shock absorber parts quickly scrapped, looking for a more professional shops surgeon is a wise choice, we last contacted proud of Li in Guangzhou Baiyun Avenue to help.

Speaking of Audi A6L car head first reaction is business, calm. The protagonist is this business today reveal sporty, with 170 horsepower and torque of 280 A6L 2.0T. With the 7-speed CVT automated manual gearbox, making 0-100 acceleration of only 8.5 seconds. It is not easy for a curb weight of 1715
Lexia-3 USB Cable  kg of Commerce sedan. 2.0 engine displacement plus turbocharging system, the equivalent displacement engine work will be greater than the 2.0 naturally aspirated engine, the smoothness requirements on the exhaust pipe is also relatively high, will enable row more smooth, natural gas to enhance the work efficiency of the engine.

Owners is taking into account that, so I decided to start with the optimization of the exhaust to proceed. As can be seen from the owners choose to buy this car, the owner of a successful business man, and the vehicle has a high taste and requirements. After some consideration and compare selected the protagonist in this article --- the Endian dual flat drum 4 CGW exhaust. The Cikuan the exhaust 
Puce de clé automobile middle of drums, so that the exhaust more smooth, directly to the exhaust after M drum can produce strong convection sound boring, high-speed sports car effect will be similar sound. 2MM thick 304 stainless steel piping used in all, so the actual traveling will not produce resonance.

Direct injection gasoline obd2 tool engine technology

The total number of car owners that certain brands obd2 tool  have direct injection technology is very advanced, even many people Bong artifact With it leading the pack. With that way of thinking, or as a benchmark for the first product to other brands, other models foot, it only shows a frog in a well. In fact, direct injection technology from birth has been nearly 90 years, many depots during this time to explore the feasibility and practicality. To this end, we particularize this article for a review of the course of development of the direct injection, especially after the popularity of the EFI engine, from the beginning of the 1990s, it is how to walk
With the increasing intensification of the contradictions of the development of the automotive industry and energy shortages, how in the pursuit of high-power, low-carbon environment to maximize the full potential of the engine at the same time respond to the tide, even if it is a multi-point fuel injection technology can not meet the requirements of the people . The saying goes, there is a demand market, so just gave birth to the emergence of new technologies, more precise injection technology was born, that is, direct injection technology.
For internal combustion engines, direct injection (GDI) can also be referred to as called spark ignition direct injection (SIDI) fuel 
OBD2 Scan Tool stratified injection (FSI), it has been widely used in today's two-stroke or four-stroke gasoline engine. Practice distinct from the fuel nozzle is placed on the intake manifold, the direct injection is the fuel injector is placed within the cylinder, through the high-pressure fuel pump, the fuel injection into the combustion chamber, so atomization more meticulous, more uniformly mixed with the air, to ensure a more smooth and efficient combustion of the fuel.  

The direct injection to achieve a more accurate control of the proportion of the mixed gas, to eliminate the disadvantages of direct injection in the cylinder outside. In the same time, the position of the nozzle, the spray shape, the intake air quantity and the intake air pressure, as well as the combustion chamber of different designs can change the ratio of the mixed hydrocarbon, in order to  http://lexia3.blogcu.com/5-elements-to-improve-autocom-cdp-pro-car-audio-sound-quality/12996289 achieve homogeneous combustion or stratified combustion. Direct injection stratified combustion based on lean-burn technology to improve fuel efficiency to ensure high output while reducing fuel consumption. In an era of environmental protection, low-emission, high-power, direct injection technology represents an important technological innovation of traditional gasoline.

Analysis of variable mb star c3 turbine technology

The turbocharger is a stunner of a love-hate relationship mb star c3 many played with a friend of "T" has the experience, especially some of the old petrol supercharged model. Natural turbocharger unparalleled high speed power love, hate nothing more than the "turbo lag" effect (for some civilian players feeling particularly). Ever since, the car engineers tried various methods to shorten the time of the "turbo lag", now the already considerable part of the model has been very dynamic linear plot close to the naturally aspirated engine, variable turbine blade technology is a model.
Hybrid turbo turbocharger variable throat, variable turbocharger tongue or the protagonist of this variable vane turbocharger turbine are inseparable from a design rule, it is a disguised form A \ R value Trim value with the speed change effect.
HKS produced the GT2530 turbine hybrid representatives take a small turbine compressor. The compressor A \ R value of 80, the turbine A \ R value of 60, and has a low speed small turbo responsive advantages, high speed rely on large compressor to ensure horsepower advantage. The disadvantage is that if the mix is ​​too extreme, prone to discharge pressure is too large even meltdown leaves. The solution change sensitive wastegate exhaust pipe of large diameter and high strength titanium alloy blades
This technology actually been 
BMW GT1 applied early in the diesel engine, named VGT (Variable Geometry Turbocharger). Why only mention the diesel engine it? Because the diesel engine's exhaust temperature is much lower than gasoline (1000 degrees gasoline, diesel 400 degrees), the requirements of the materials is much lower than gasoline, so widely used. The first hands-on is a sports car the nobles Porsche 911 disadvantage can not be arranged on the innate shape than 4.0L displacement greater level of the mid-engine, so must leave no stone unturned anywhere press power, the turbocharger is natural one of the "key point".

 Porsche eventually teamed BorgWarner overcome this problem (famous BorgWarner's KKK but the turbine manufacturers oh), lies in the use of high-temperature aerospace materials as variable vane, which developed the first equipped with variable turbine blade technology petrol engine. Subsequently, the Porsche name  VAS 5054A  VTG (Variable Turbine Geometry).

Talk about a double Nissan Consult 3 wishbone suspension

The double wishbone suspension in the form Nissan Consult 3  known as double rocker, also according to the shape of the cross-arm, named the double A-arm or double wish bone. The double wishbone suspension, the English name "Double Wishbone", it really is a double wish bone. Double wishbone wishbone, in addition to the outside much like with the letter "A", and the similarity of "Wishbone" is more subtle. Birds animals such as chickens, ducks, a bone between the neck to the back, similar to the mammalian collarbone. After Thanksgiving dinner meal turkey, it will leave the root of the V-shaped bones, two people each carrying one end of it it snapping, we believe whose hands get larger half will wish come true, hence the name "the Wishbone. The shape of the bones, and is very similar to the wishbone, "Bones" and "rocker" function also has a subtle similarities, so they took this image of the "Double Wishbone" in the form of this suspension, but also give full expression to the name of its role.
Double wishbone has two generally "V"-shaped cross arm up and down arrangement. The force double wishbone suspension, vertical and horizontal lateral torque by double wishbone to pass, while the shock absorbers and column throughout the two cross arm in the middle of space, only need to take the cylinder direction along the shock machine axial force. Depending on the depot, the design of the different models, double wishbone morphology has a vastly different changes, such as the Honda Civic, rear double wishbone structure on the cross arm is a banana-shaped lower wishbone wishbone trailing arm "T"-shaped combination.
The double wishbone widely used in racing, precisely because of the show the advantages of the double wishbone, fully meet the 
Nissan Consult Diagnostic Interface system requirements of motorsport racing suspension. First, double-wishbone can be very simple to get the high strength of the structure, and less use of materials. Through the length of the wishbone, wishbone plane angle, the mutual distance of the upper and lower wishbone, and the relative position and angle adjustment, can adjust to different tire trajectory parameters such as braking kingpin angle to increase to inhibit bend forward steering the outside wheel tread should be as perpendicular to the road surface contact and so on.

 Uneven force the last double wishbone system of shock absorbers, and does not require such as McPherson generally strong tower, the favorite won the Formula One racing does not exist at the top of the tower, and it is easy to achieve pusher shock absorbers design, of course, it is unrealistic for the average civilian car. The downside, only the most obvious is the double wishbone need to occupy a larger  Nissan Consult III body space, which rarely appear in compact models. Plus manufacturing costs relative to McPherson, double wishbone suspension become an advanced positioning symbol of sports performance.

Notes of Volvo VIDA DiCE modification

Trap one: the private change the engine power

    
"As long as your car over the license, and how to change
Volvo VIDA DiCE  it no problem, we can enhance the performance of your car than the factory a!" Mr. Sun to Qi Bohui D Hall, a car service company reporters to lay such a "package vote". He said, to improve the performance of the car, the most important is the "modified" the engine, just to keep the original engine number, all performance increase. 250 horsepower engine after "adjustment" can reach 350 horsepower.

      
In response, Jilin University, vice president of automotive engineering Professor Song Zhuanxue pointed out that from a technical point of view, without permission to increase engine horsepower is very difficult, because the capacity of the engine are limited, and the horsepower increase energy will be larger, the slightest mistake, the engine will be scrapped.

 
Trap: arbitrarily increased displacement

    
Even as emission measure an important indicator of the performance of the car, one car, can change their men!

    
The modification technician 
Renault CAN Clip said, only increases the car into gas and displacement, in order to meet the need for super-high-speed car, so this modification is to become a motorcycle racing "essential step.

   
The Song Chuanxue displacement size of the car, depends entirely on the cylinder model, based on the overall configuration of the car, the size of the cylinder are generally fixed, so the size of the feed rate and displacement also can not be altered. Car modification company called "increase into gas and displacement", in fact, an almost brutal force to change the performance of the car, if it could be converted successfully, the car's overall coordination and security there are a lot of potential threat.
Trap three: the removal of part of the safety equipment

   
Car modification company in another exhibition, a staff member told reporters that the company can change the chassis of the car, bumper models, to change the layout of the circuit, the circuit, you can also remove part constraints vehicle speed ancillary equipment.

   
In Song Chuanxue a car design from initial drawings to the final formation of the finished product, in the middle to go through 
vas 5054a numerous manufacturers researchers rigorous testing and calculation, so the car factory layout arrangement and parts configuration are not any change, but not at liberty to remove some of the protection of automotive safety equipment. Changchun Automotive modification industry point of view, most of the practitioners and technical personnel operating level or not reassuring.
