ガソリン噴射電気点火式機関の燃焼率

抄録

In this paper, the rate of combustion in the cylinder of the gasoline-injection engine is calculated by analyzing the indicator cards, and the relations between the rate of combustion and thermal efficiency, and the effects of the combustion progress on the performance are investigated. In the fuel-injection engine, the combustion proceeds faster at the early stage after ignition than in the carburetor engine. The nature of the cycle, therefore, resembles to that in the constant volume combustion cycle and has good thermal efficiency. The highest indicated thermal efficiency is obtained when the spark is so timed that the highest rate of combustion appears right after TDC.
