机车柴油机振幅大的探析

Analysis of Big Diesel Engine Amplitude in Locomotive

影响柴油机振幅大的主要原因是喷油量的均匀性实验观察到不同转速下振幅随柴油机功率而变化的规律,用变化规律检验振幅-量比算式的适用性.结合算式,再从理论上找主要原因的作用方式,说明均匀喷油量对机车柴油机保养的重要性.

The main reason caused big diesel engine amplitude is the uniformity of oil injection quantity. A law is found out through experimental observation, i.e. amplitude under different rotary speed dependence of diesel engine power, and test the applicability of amplitude-quantity relative ratio formula with change law. It shows that the uniformity of oil injection quantity is important to the maintenance of locomotive diesel engine via combining formula and finding out the function mode of main reason in theory.
