Integrated building block system structural put engine contains up to 25% fewer parts than competitive engines in its class, ensure design intensity to through strict basis of test experiment, reduce the size of parts reasonable, not only to reduce the size and weight of diesel, but also bring down the failure rate and maintenance costs. Put turbocharged and turbocharged with after cooled as major products to improve the dynamic character and economical efficiency. Efficient fuel supply system and air intake system put fuel and air mixed fuller, burning totally and lower discharge of pollutants.
