Summary:

The ignitability and engine performance of FAMEs at the cold condition were experimentally investigated by using two FAMEs, id est coconut oil methyl ester (CME) and soybean oil methyl ester (SME). The cold start test and forced over cooling test were conducted. In the forced over cooling test, engine was forced cooled by the injecting water mist to engine cooling fin. In the cold start test, the cylinder pressure of CME rose earliest because CME has a superior ignitability. The crank angle at ignitions of diesel fuel and CME were not so affected by the forced over cooling, however ignition timing of SME was remarkably delayed. In cases of forced over cooling, COV of maximum combustion pressure of CME was lower than that of normal air cooling condition. The forced over cooling has a potential to reduce NOx emission, however HC, CO and smoke concentrations were increased in a high load due to incomplete combustion. The incomplete combustion was relatively suppressed for CME as compared with other fuels. The high load operation could be achieved by the forced over cooling because of improvement of charging efficiency, however the brake thermal efficiency was deteriorated due to an increase in cooling loss
