Summary:

The potentiality of direct injection (DI) diesel engines for passenger cars has been examined by comparing the characteristics of fuel consumption, exhaust emissions and noize levels between a turbocharged DI diesel engine and a turbocharged IDI diesel engine with the same displacement, 4 cylinders and 2 liters.It was observed that improved fuel consumption was obtained as the engine load increased, namely, 10 - 15% in the higher load range and 5 - 10% in the partial load range. In comparison to the IDI engine, the exhaust emissions of the DI engine tended to contain two or three times higher NOx and HC, and also about 30% higher particulates. Further, the noise levels of the DI engine were approximately 2 - 4 dB (A) higher than those of the IDI engine. It was suggested from these results that in those countries which have stringent emission and noise regulations several years would be required to introduce small, high speed DI diesel engines for passenger cars to meet with these regulations
