Auxiliary branch intake port for diesel engine

Abstract

The invention relates to a diesel engine auxiliary branched air inlet way, and belongs to the field of diesel engine air inlet way structural design. An air outlet of the auxiliary branched air inlet way and a diesel engine air inlet way are connected at the position close to an air inlet valve seat, and the connection position is in smooth transition. The auxiliary branched air inlet way can be distributed in the manners of being parallel to an air cylinder cover, being vertical to the air cylinder cover and inclining relative to the air cylinder cover, or the auxiliary branched air inlet way can be distributed in the manners of being parallel to a traditional air inlet way, forming an mirror image together with the traditional air inlet way and rotating around the axis of the air inlet valve seat with reference to the air inlet way. By additionally arranging the auxiliary branched air inlet way, the air inlet amount of a diesel engine can be effectively increased, the strength of airflow entering a burning chamber is improved, mixing of fuel and air in the burning chamber is promoted, the fuel consumption rate and the pollutant emission amount of the diesel engine are reduced, the working zone of the diesel engine is expanded, and the comprehensive performance of the diesel engine is improved.

Description

technical field [0001] The utility model relates to an auxiliary branch intake port of a diesel engine, which belongs to the field of structural design of the intake port of a diesel engine. Background technique [0002] On the one hand, my country's smog pollution has been serious in recent years, and motor vehicle exhaust emissions are one of the important factors causing this situation. Therefore, it is very important to improve the combustion quality of diesel engines and reduce the emission of harmful pollutants. On the other hand, with the implementation of increasingly strict fuel consumption limit regulations for motor vehicles and the increasingly strong demand of consumers for low fuel consumption, how to reduce the effective fuel consumption rate of diesel engines is therefore extremely important. [0003] For traditional diesel engines, due to the limitations of the intake system, the strength of the intake air field is not enough to promote the rapid and effici...

AI Technical Summary

Problems solved by technology

[0003] For traditional diesel engines, due to the limitations of the intake system, the strength of the intake air field is not enough to promote the rapid and efficient diffusion and air mixing of diesel in the cylinder, resulting in uneven distribution of the mixture concentration in the combustion chamber and insufficient fuel combustion. Under load conditions, the air intake of the diesel engine is insufficient, which leads to a discount in the performance of the diesel engine
