Abstract
Increasing cost of petroleum fuels, fast depletion of petroleum resources and excessive automotive engine pollution lead to the researchers to search for an alternate fuel like waste lubricant oil and Waste Transformer Oil (WTO) for Compression Ignition engines. In the present investigation, WTO is blended with diesel fuel in the ratio of 30:70 (WTO30) on volume basis and is used in a diesel engine to evaluate the performance, emission and combustion characteristics. Initially the engine was operated with diesel and WTO30 and then the test was repeated with WTO30 at different compression ratios. The results revealed that the BTE was increased by 1.12% at CR20 and CO, HC and smoke emissions were decreased and the NOx emissions were increased for WTO30 with an increase in CR when compared to that of diesel. The cylinder pressure and heat release were increased for WTO30 at CR20:1 compared to that of WTO30 at maximum load.
