As the world a few big R&D and manufacturing high pressure common rail diesel engine of one of Germany BOSCH company in the guangzhou auto show the application on some technical achievements in diesel engine, the application of the technology that diesel engine in low noise, high efficiency and low pollution and won the progress.

The BOSCH high pressure common rail fuel injection pressure technology up to 2000 bar, the higher of the injection pressure can will fuel atomization better, burning more fully, further improve the engine’s efficiency, and according to the size of the engine can be equipped with different high-pressure pump, makes this technology application level more widely.

AMT transmission technology and low cost because the threshold, has in many independent and joint venture car has been on equipment. BOSCH shows the machine has been used in the AMT transmission rush rush MINI above. BOSCH will himself the AMT transmission system called IMT, also is the “intelligent transmission”, whether intelligence was unknown, but it is really improved the use of user convenience.

BOSCH used many times fuel injection technology, in a cycle of engine cycle will spray for the jet, the oil spray and spray after three stages. The jet function similar to EGR waste gas recycling, can reduce the temperature inside the cylinder, so as to reduce the emissions of nitrogen oxides, also can reduce the noise of the burning, and then spray can reduce exhaust in the particle emissions, and the technology for car cameras each cylinder situation can be calculated separately for each of the injection quantity and precise injection time, this also is the full use of every drop of oil, improve the economy.

BOSCH show this machine double clutch transmission is also applied DCT in horizontal buy precursor platform, maximum input torque 170 cattle·m, assembly containing 65 kg net, and five forward gears also let its structure and the transmission automatic control has simplified. And from a transmission principle on look, it and other DCT transmission no much difference, using electric hydraulic drive shift institutions, also with the safety starting ramp function, at the same time, the transmission where possible, will choose to block up as soon as possible, and let the engine is the speed of the interval as low as possible, in order to improve fuel economy.
