The Light Duty Diesel Engine for Private Transportation

On the basis of European experience, the small high-speed diesel engine is an obvious alternative to the gasoline engine to achieve better fuel economy.

This paper looks at the benefits which would result from the diesel engine in terms of economy, exhaust emissions etc., when applied to American type light-duty vehicles. Areas requiring further development to make the diesel more socially acceptable are also discussed.

Specifications are proposed for two engines of 100 and 150 hp which should satisfy the requirements of private cars, taxis, light delivery vans and recreational vehicles.

It is concluded that the diesel engine can make a significant contribution to fuel economy within moderate exhaust emission legislation.
