摘要：In order to reduce the excess pollutants caused by environmental factors, on the basis of the installation of post-treatment device, through the use of converse software, the simulation research on the combustion process of non road diesel engines in the cylinder was carried out in the cold environment, and the combustion processed and emission reduction of diesel engine were optimized under the condition of only changing the angle of oil beam. The results show that the temperature in cylinders is the highest, and the pressure in the cylinder is larger, the equivalence ratio and eddy current intensity in cylinder are stronger, the emissions are lower, and the emissions of NOx and soot are the lowest under the angle of 164° fuel beam.
