Predictions of the Performance and Exhaust Emissions Produced by Small Light Duty Vehicles Powered by DI and IDI Diesel Engines

摘要

This report describes an exercise in which a computer simulation program was used to predict the likely performance, fuel economy and exhaust emission levels of light duty vehicles weighing from 1000 to 2000 lb. when powered by naturally aspirated diesel engines of 0.8 litre displacement having direct injection (DI) and indirect injection (IDI) combustion systems. It was assumed that the vehicles were fitted with an efficient continuously variable transmission.
