Turbo diesel engine technology used in the cold exhaust turbocharger technology, to fuel combustion, can reduce the CO and HC of the generation. But Jin temperature increased, so that NOx emissions have increased, the use of pressure and with intercooler may also reduce the HC, CO, NOx emissions. In the cold by turbo diesel engine technology could also enhance the power, equipped with a turbo-diesel engine power output than not installed supercharger to increase 20 percent to 30 percent, while use of booster technology even in cold 50% of the power increase. New Turbocharger the use of means that can be used small engine displacement of large displacement of alternative engines, reducing engine and vehicle quality, improve the economy and emissions of.
A multi-valve technology could increase Multi-valve diesel engine into the air, so that a more thorough combustion of diesel, exhaust faster and more thoroughly, so as to enhance the engine's power output.

EGR technology to ensure it does not reduce engine power of the premise, according to the temperature and engine load size, amount to be part of the introduction of emissions into the trachea and then into the cylinder so that the combustion reaction slowed, reducing the maximum temperature combustion , To reduce NOx emissions. Especially in the cold EGR technology, not only to reduce NOx emissions, but also to maintain its low-emission pollution emission levels.
