This paper deals with the development of a light high speed diesel engine at low cost for saloon cars with an operating cost and driving performance comparable with the gasoline engines. The development centered around using existing manufacturing techniques as used on gasoline main engine components and engine cylinder blocks for the diesel engine. Initial design and development investigations and design and development of the production engine are discussed.
The work has resulted in the production of the 2.1 liter diesel engine, installed in the Opel Rekord car with 1.210 kg curb weight. With its 60 hp performance and 12.0 mkp torque, the engine gives the car a sufficient driving characteristic and reserves a good market share, especially in those countries where the diesel fuel is remarkably cheaper than petrol.
