Engine Performance Testing in Diesel Engine for Laboratory

Abstract

This research was aimed to design and build diesel engine testing. ESC Test Cycle was modified to be a testing standard. A single cylinder diesel engine which power was transmitted through the electricity generator using the belt and pulley was used for the experiment. The engine was tested and measured the rate of fuel consumption at the engine speed of 1,200 to 2,250 rpm and loading of 500 to 4,500 Watts. The results showed that the lowest brake specific fuel consumption was 344.56 g/kW.h and the highest fuel energy conversion efficiency was 24.58 percentages at the engine speed of 2,100 rpm and loading of 4,000 Watts. However, the engine’s power was maximized at 4,500 Watts with the engine speed of 2,250 rpm but lower than the engine’s standard (5,200 Watts at the engine speed of 2,200 rpm), due to the engine has been used and the engine’s parts were deteriorated. This factor caused that the brake power was lower than the engine’s standard. However, this engine performance testing in diesel engine for laboratory gave the useful data for testing and determining the engine performance.
