摘要：
This aim of the current study is to evaluate the performance and emission characteristics of pumpkin seed oil with diesel at different blended ratios (B10-CR15, B20-CR15, B10-CR18and B20-CR18) in a constant speed (1500 rpm) engine. The tests were conducted at various loads of the engine and with specific compression ratios of 15 and 18. The performance and emissions were compared with the different blend ratios and compression ratios. As a result of which the higher compression ratios shows better performance and emission than the lower compression ratio; among them B20-CR18 shows better results such that CO2, HC and CO emissions were reduced and there is a slight increase in NOx value compared to diesel and other blend ratios and also there is an increased brake thermal efficiency for the blend B20-CR18. This shows that the optimum blend is chosen from the results is identified as B20-CR18, which has better performance and emission than other blends and compression ratios.
