The objective of this paper is to clarify the problems encountered with the installation of diesel engines in passenger cars and light duty commercial vehicles. As an example, Nissan Diesel's SD series light duty IDI engines are introduced.
Described herein are the design concept, including determination of cylinder size, cylinder configuration and structure and function of the components particular to diesel operation.
Output performance, fuel economy, exhaust emissions and noise are also described. Exhaust and noise emissions are yet to be improved.
The critical acceptance factors of diesel passenger cars are discussed with special emphasis on fuel economy, noise, roughness and drivability.
