Simulation Analysis of Gas Phase Optimization for 4190 Type Marine Medium Speed Diesel Engine
摘要
Abstract
The working process model of the 4190 type marine medium⁃speed diesel engine has been es⁃tablished with the MATLAB/Simulink software. The accuracy and dependability of the model were verified by comparing the simulation results with experimental data. The influence law of gas phase offset on diesel engine power, torque, fuel consumption rate, combustion temperature, combustion pressure in cylinder, NOx emi⁃ssion, exhaust gas temperature, charging efficiency was studied through simulation with the model. The opti⁃mized gas phase has been identified that�s, inlet advanced angle 66℃A ( crankshaft angle); intake lag angle 54℃A; exheaust advanced angle 58℃A; exhaust retard angle 56℃A, conclusions are drawn that the simu⁃lation results are beneficial to the performance optimization of 4190 type marine diesel engine.关键词
