The results show that the average of 2115 diesel engine cooling jacket overall rate was 1.0036m/s, the overall heat transfer coefficient (HTC) with an average of 7767W/ (M2 K), generally meet the cooling requirements, but the exhaust area for cooling large thermal load around the nose area is still insufficient, and the two cylinder cooling is not uniform, the need for structure optimization.

(controllable pressurized air mixture with air or gas) by the side of the auxiliary cylinder inlet charge into the cylinder controlled by optimizing the inflation to the side of the cylinder, realize the airflow motion in the cylinder composite complex, to achieve a richer mixture near the spark plug and the lower part of a lean mixture stratified charge gas effect, so as to realize the partition homogeneous lean combustion. Auxiliary air intake realize the stratified combustion based on the idea of a small gasoline generator with 168F petrol engine as the research object, mainly studies the universal small gasoline engine based on the layered cylinder side auxiliary intake to achieve lean combustion and its influence on fuel economy and emissions.
