Experimental studies on energy appropriation in a single cylinder diesel engine

Abstract

The energy produced due to combustion of fuel in an engine is partly converted into work and the rest is lost. The knowledge of how the energy is lost will help in finding means to reduce the same to improve the performance of the engine in terms of efficiency and power output. In the experimental work, reported in this paper, a single cylinder, naturally aspirated. 4-stroke diesel engine fully instrumented for the measurement of engine output, speed, fuel consumption, air flow rate and temperature of the cylinder liner and exhaust gases and lubricating oil, was used. Estimation of energy lost due to heat transfer to engine components was arrived at.
