摘要：Abstract Improving the performance of internal combustion engines and ensuring the reduction of pollution by the application of an advanced technology constitutes one of the main keys for safe guarding nation's economy and health. In this context it is pertinent to note that in terms of brake thermal efficiency and brake specific fuel consumption, a single cylinder four stroke engine acquires a better performance with 15% diethyl ether (DEE) as an additive to diesel. Thus, the present investigation is motivated to compare the performance of the engine when run with diesel alone and when it is run with additives like ferric chloride (FeCl3) and diethyl ether. The experiments in the laboratory establish lowering emissions of CO, HC and smoke (excluding NO) with diesel and DEE additives compared to that with diesel and FeCl3 additives and diesel alone.
