Currently, the car has been to prevent the use of diesel exhaust turbocharger technology, but the application of turbo diesel technology is much more difficult than on gasoline, mainly due to: 1) gasoline engine ignition ignition (diesel compression ignition), the compression ratio has a range of restrictions, if the compression ratio is too high will lead to exploding, so turbocharged gasoline increased after knocking tendency. 2) Due to the excess air ratio gasoline combustible mixture of small, high combustion temperature, thus after booster gasoline and turbocharger heat load. 3) Motor gasoline mechanic conditions change frequently, speed and power a wide range Skoda 1.8 turbocharger, resulting in more difficult match turbocharger and gasoline. Poor acceleration 4) turbocharged gasoline engine.
When the throttle opening suddenly increase rapidly increasing requirements of the gas mixture, the turbocharger rotor inertia but because leaving accelerate slow, so an increase in engine intake air for some time lag. This is commonly known as "turbo lag" phenomenon. A lot of people rich enough driving experience driving the installation of a large pressure ratio turbocharger car, at the risk of turning often, it is because "turbo lag" phenomenon. Since the need to reduce the stalls while driving into the corners, the slightest mistake will make lower after gear speed increase over the opening point of the turbine, when a sudden increase in power will make the car drift out of control, which is very dangerous.
Complete elimination of the turbocharger on the engine operating conditions change in response hysteresis difficult. However, car engines, particularly car gasoline turbocharger technology in recent years has been substantial development. This is because with the development of the highway, the owner of the car high dynamic performance increasingly strong pursuit. In addition, the development of gasoline injection engine 4 cylinder turbocharger and electronic control technology, as well as improve the performance of the turbocharger, have created favorable conditions for the spread and development of gasoline engine supercharger technology. Nevertheless, with the exhaust gas turbocharger ways to enhance gasoline engine intake pressure remains limited deflagration, so supercharged gasoline engine does not spread.
Turbochargers, exhaust gas turbocharger full name, is a supercharged car engine widely used way. The turbocharger consists of a turbine and a compressor (also known as compressor) constituted by the engine exhaust inertia momentum of the exhaust gas to drive a turbine inside the turbine, thereby driving the turbine coaxial with the compressor impeller, the impeller and then press send air filter incoming air duct so that after being pressurized into the cylinder. When the engine speed increases, the exhaust gas discharge speed and turbine speed also simultaneously increases, the impeller will compress more air into the cylinder, so that more fuel into the cylinder for combustion, and therefore increases the engine power output. Turbocharger engine without mechanical contact.
This supercharged way to effectively use the energy of the exhaust gas turbocharger, the fuel economy is better than a non-supercharged and supercharged engine, and can greatly reduce the emission of harmful gases and noise level. After an engine 4 cylinder 2.0 turbocharger fitted with a turbocharger, the maximum power output is not installed when compared with the turbocharger, increase about 40% or more. However, after the introduction of the engine exhaust gas turbocharger technology, the maximum explosion pressure and average temperatures generated will greatly increase, so that the engine's mechanical performance, lubrication performance will be affected.
To ensure the supercharged engine at high mechanical load and thermal load conditions can be reliably work durable, must make the necessary changes in the selection, design, materials and process selection The main thermodynamic parameters of the engine, rather than simply in upload a turbocharger engine on it. Since this process of change in the real Yan quite difficult, but also consider the matching between the turbocharger and the engine, and so to some extent also limits the application of the exhaust gas turbocharger on the engine. Further, since the turbine is a fluid mechanical means while the engine Toyota 2.0 turbocharger is powered mechanical device, therefore turbocharged engine torque at low speed is increased much, and when the engine operating conditions change, poor transient response, resulting in car acceleration , in particular the low-speed acceleration is poor.
Recently, foreign media broke the news of more information on the Porsche electric car, the car in the fastest possible 2017 - launched in 2018. This positioning of large electric car size and standard wheelbase BMW 5 Series considerably. Printing already heard very much like a Porsche Volkswagen Group to launch an electric car to compete with the Tesla.
It is reported that this is the use of electric vehicles is likely in 2012 launched Panamera Sport Turismo concept car design coilovers for sale, different from the traditional sedan's styling will make it unique, add this selling electric cars. So, the car's exterior styling already have, more work will be left to the chassis set-up and optimization of electric drive technology. Because even an electric car, it also must have a Porsche sports nature. The car will be based on the chassis part MSB platform to build, but will go through some adjustments to fit the battery and place the rear of the motor. The rear axle will be two motors, and they were about to drive the rear wheels, low-power version of the maximum power will exceed 420Ps (309Kw), mileage of at least 424 kilometers to see Qitesila Model S.
In addition, this platform excellent compatibility and flexibility, so that the car can be introduced in addition to the pure electric version, you can launch a fuel cell version of the model coilover suspension. It is particularly worth mentioning is that Porsche is also developing their own inductive charging system (induction charging system), that is, we often say that the wireless charging system that allows the charging process can be more convenient and faster.
Recently, the Mercedes-Benz A-class car with a no camouflage photo was exposed, some adjustments to the appearance of the new car was revealed. From the beginning of July will be accepted according to the German news media facelift A grade book is delivered to customers beginning in September, will also meet with the public in the same month at the Frankfurt Motor Show. A facelift level mainly on the front face has been modified, mainly the front headlight and bumper in two parts. First headlight lamp vessel shows like new, refined feeling stronger. And this should look facelift headlights class A latest optional intelligent LED headlights (single lens), it can provide a wider and brighter lighting at night.
In addition, changes in the shape of the front bumper is also evident, sporty stronger, we guess is a common version of the bumper, Sport Sport will have a different design. In addition, modified cars from this unique green vehicle performance car parts color and also the new hub to determine the estimated number of new exterior colors and an optional profile. Photos facelift this car rear no exposure, but according to the previous spy photos we know facelift car rear light style change, but also adopted a new internal LED turn signal group, also has a new show wide light display. The new exhaust pipe is similar facelift E, the new generation C-Class family style. Dynamic aspects, A-class was originally shared with B-class car, so it will be followed by B-class facelift. Main engine 1.6T engine, power output there 122Ps (90Kw) / 200N • m and 156Ps (115Kw) / 250N • m in two versions, additional A250 (domestic referred A260) the 2.0-liter turbocharged engine, maximum horsepower 211Ps (155Kw). A220 4MATIC four-wheel drive version of the car maximum horsepower 184Ps (135Kw).
It also includes A160 CDI, A180 CDI diesel engine models and other merchandise. The 7-speed dual-clutch automatic transmission, suspension systems will be upgraded accordingly. As for the performance version engine parts of the facelift AMGA45 performance version of the model, it will add an S version, power output performance might reach 385Ps (283Kw). At the same time, of course, facelift AMG A45 also will have a new enclosed design, bring more freshness, a sense of movement has also been further enhanced.
Recently, according to foreign media reports, the Volvo S90 models will debut at the January 2016 North American Auto Show. According to reports, before the North American Auto Show debut, Volvo will release a series of warm-up figure. S90 sedan will be based on the new XC90's SPA platform to build, this car will replace the cash to become the new flagship S80. In addition, the car will launch travel version. Styling, the car will reference Universe concept car styling.
Dynamic aspects, S90 XC90 is equipped with power will continue, equipped with Drive-E Series 2.0T engine E46 camber arms, the new car is expected therewill be a plug-in hybrid models introduced T8. For more information, we will continue to focus. Overseas media reported that a few days ago, the new smart fortwo / smart forfour electric version of the car will be officially launched in 2016. It is reported that the new smart fortwo / smart forfour electric version will be based on a common version of the model building, its overall shape with the regular edition remained the same, but it will be integrated into many green elements on the basis of the two cars.
Cash smart electric drive electric version of the model X3 camber arms is equipped with a flat output 75 hp and peak torque of 130 Nm of magnetic motors, as to whether the new version will continue the smart electric power equipment, the official were not disclosed.
Audi, Mercedes-Benz, BMW, Volkswagen, Ford and other well-known manufacturers in the production or on its concept car product was added to the gesture recognition technology. But the recognition rate and the use of fluency in these products is not perfect. This is more related with the current degree of perfection of image recognition algorithms. Now in the field of gesture recognition technology more leading companies belong to IT companies. The car manufacturers are using gesture recognition system more or less have a certain relationship with IT companies.
Faced with competition from IT companies in the electronics field has a strong R & D strength of parts suppliers, such as: Bosch, Magna, Continental automotive electronics, will not sit still, I believe a similar gesture recognition M3 camber arms solutions will all be introduced to meet the changing needs of the automotive industry. Can be expected, with hardware computing capabilities continue to improve, and constantly improve gesture recognition software, gesture recognition automotive applications will be increasingly sophisticated. Practical experience results from Audi on display at CES Asia gesture recognition system perspective, the interactive design is more convenient, but the accuracy and fluency using gesture recognition there is still some room for improvement. Microsoft, Intel, Apple these three IT giants are highly valued prospects gesture recognition and image processing technology, and effort to develop related
technologies. This prompted the development of such technology Z4 camber arms to accelerate, improve the speed of the car also makes use of gesture recognition technology is growing. Coupled with the traditional auto parts suppliers waves in the field. I believe have the practical and has a good user experience gesture recognition technology will soon be "landing" onto automotive products.
Prior Design is a German excellent conversion manufacturers, especially in the more favored by many fans for BMW, Mercedes and other European models introduced kit, and now they turn targeting the Japanese national treasure-level models Nissan GT-R body. First to greet the GT-R is very wide-body kit Prior Design characteristics, exposed rivets widebody wheel eyebrow looks full of wild, adding new front surround kits and blackened headlights, so this car GT-R instant fierce look absolutely shattered.
In addition, the newly designed 21-inch alloy wheels coilover kits, further highlighting the motion characteristics of the car. Of course, the fierce appearance also need a strong incentive to set off, for Prior Design the GT-R's twin-turbo 3.8L V6 engine's maximum power up to 720 horsepower and peak torque is 850 Nm, compared to under the Nissan GT-R coilovers uk Nismo maximum power "is only 600 horsepower of it." Not only that, Prior Design also prepared for this car the KW V3 unscrewing damper together to enhance the combat effectiveness of the car.
In the future development plan, PSA Group in Europe in 2015 to achieve the 130g / km of carbon dioxide emission targets, while in 2020 this figure was 94g / km, lower than the standard EU requirements. For the Chinese market, PSA's goal is 2020 in China at the average carbon dioxide emissions of vehicles sold was 95g / km.
Previously, PSA Group has launched 1.2THP engine turbocharger suppliers, the engine's maximum power of 136 horsepower and peak torque of 230 Nm. Currently overseas, Peugeot 208 and other models have been equipped with this small displacement turbocharged engine. DPCA at the end of 2013 to achieve a 1.2THP engine made.
Currently, the Peugeot 408 and Peugeot 308S models 1.2THP has been officially listed in China, C4L 1.2THP models are also coming into the market. Thus, these domestic models displacement PSA adjustable coilover will also be toward the lower direction.
