The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas

Read MoreThe engine performance deteriorated with WLB blends against diesel operation. Among the blends, D90WLB10 showed 4% and 6% higher BTE than D80WLB20 and D70WLB30, respectively. Addition of 10% by vol of WLB to diesel increased the NOx emission, however, it suppressed as the proportion of WLB increases.

Palm oil is now already produced and marketed in very large quantities, because it is edible and is high yielding (+/–3 ton/hectare/year).
Read MoreTests were performed in a single cylinder, four stroke, unmodified, and naturally aspirated DI high speed diesel engine at full load and four engine speeds (1400 rpm, 2000 rpm, 2600 rpm, and 3200 rpm) by using six test fuels. The experimental test results showed that the DI diesel engine can run with the TDF fuel blends up to TDF90.
