Turbocharged diesel engine using technology in the cold exhaust turbocharger technology, to fuel combustion, which reduces CO and HC of the formation. But inlet temperature increased, the NOx emissions has increased, the use of booster and fringe intercooler may also reduce HC, CO and NOx emissions. In the cold by turbocharged diesel engine technology can improve power, with a turbo-diesel engine power output than not installed supercharger to increase 20% to 30%, while use of technology and even turbo-charged 50% of the increased power. New Turbocharger the use of means that can be used in small-displacement engine alternative, larger engines, reducing the engine and vehicle quality, improve the economy and emissions of.
Multi-valve technology can be multi-valve diesel engine increases the feed rate, the diesel combustion more thoroughly exhaust faster and more thoroughly so as to enhance the output power of the diesel engine.

EGR technology is the engine driving force in the performance guarantee under the premise of not lower, according to the engine temperature and load size, suitably emissions will be part of the introduction into the trachea and then into the cylinder so that the combustion reaction has slowed, the lower the maximum combustion temperature , thus reducing NOx emissions. EGR especially in the cold, not only to reduce NOx emissions, but will also maintain its pollution emissions from the low-emission standards.
