摘要：用美国EPA八工况法对NJ385DI农用柴油机进行了排放测量。通过排放的工况分担率分析,为控制柴油机排放提供了相应的依据。分析了EPA八工况法在测量CO、HC、NOx及PM的过程中各工况的分担率,指出控制CO的关键在于高转速与最大扭矩工况。

Abstract: The exhaust emission data from an
NJ385DI automotive diesel engine is taken with 8-Mode test cycle ofUSA. Based on
the calculated contributions of individual modes in the test cycle, the paper
point out the key modes for controlling emissions are high speed condition and
the maximum torque condition.
Keywords: Diesel Engine; Exhaust
Emission;Test Cycle
