Matching Calculation and Analysis of Electrically Assisted Diesel Engine Turbocharging System
Electric auxiliary turbocharged is an effective technical means to solve the problem of insufficient low-loading pressure and high-load supercharged problems of traditional diesel engines.This article takes the shipping diesel engine su-percharged system as the research object,establish a simulation model of diesel electrical auxiliary turbocharged system,and completes the model check inspection.Results showed that the model simulation predictive value and test value error did not exceed 2%,and the model was more accurate.Based on the simulation model,the impact of electrical auxiliary supercharging on the low construction conditions and transient performance of diesel engines,and in-depth investigations of the impact of the thermal efficiency of diesel engines in the power generation mode.The results show that the efficiency of turbine and gas compressors is a key factor that affects the comprehensive thermal efficiency.While increasing the power of motor,the com-bustion in the cylinder is improved,which is conducive to the improvement of power performance under low engine conditions.
