A NEWLY-DEVELOPED 1.51 CVCC ENGINE FOR SOME 1980 MODELS

The fuel consumption and exhaust gas emission characteristics of a newly developed 1.51 CVCC engine are compared with those of a conventional engine, the pressure and temperature of combustion gas in each cylinder are measured on real time in order to clarify the differences between these characteristics, and combustion analyses are made on the basis thereof. Compared with conventional engines operated at the rich air-fuel ratio (14.7), the new CVCC engine is capable of providing, not only at the same air-fuel ratio, to be sure, but also in the lean range, a stable combustion which is small in the cycle variation, whereby the fuel consumption and emissions are improved.
