Case Study on Endurance Test of LPG Automobile Engine 2008-01-2756

This paper presents results and discussions of two hundred hours endurance test carried on single cylinder four-stroke cycle LPG cargo pickup van engine. Engine was run in cycle as suggested by manufacturer. Engine was run for one hour at speed corresponding to maximum torque and then it was run for one hour at speed corresponding to maximum power. This cycle was repeated for two hundred hours. Effects of endurance test on components of engine were studied. Engine was tested before endurance test at full throttle position and same engine was tested after endurance test at full throttle position. Performance of engine before and after endurance test has been compared and discussed. Objective of this experimental work was to study effect of endurance test on different components of engine and analyze and compare performance of engine before and after endurance test. Graphs of important engine parameters have been plotted and curve fitting has been done.
