| Summary: | Alternative fuels have been explored for the substitution of diesel to lessen dependence on fossil fuel and to
mitigate environmental pollution. Opted on biodiesel seem like promising due to its availability and regenerability, as
well as ability to lower emissions. The objective of this research is to investigate the effects of ambient temperature,
injection characterirics and spray characteristics on ignition delay and combustion process of biodiesel blends derived
from palm oil and waste cooking oil. The ignition delay and combustion were observed using a rapid compression
machine with ambient temperatures ranging from 850 K to 1050 K and injection pressure ranging from 80 MPa to 130
MPa. Palm and waste cooking oil biodiesel blends fuel were produced by blending these oils with Euro5 pure diesel at
concentration of 5vol%, 10vol% and 15vol% correspondingly. Higher injection pressure and higher ambient temperature
have been found to significantly reduce the ignition delay and influences to the heat recovery of combustion, while the
higher biodiesel blending concentration of biodiesel promotes the reduction of CO emissions |
