Abstract

Biofuels are one of the largest sources of renewable and sustainable energy, which are made from organic matter or wastes. One of the main biofuels type are the biofuels that is derived from vegetable oils. Nowadays, biofuels are drawing more attention to global scientists because of the scarcity of mineral oil supplies. The primary objective of this analysis is to explore the influence of variability in ambient temperature on the ignition delay period and emission. The type of biodiesel fuel used is the Jatropha Biodiesel with three different blending ratio, which are J40, J30 and J40. The ambient temperature of constant volume chamber (CVC) Ti,cvc and  combustion chamber (CC), Ti,cc, was varied from 750 K, 850 K, 950 K and 1100 K. In the form of the hydrocarbon (HC) pollution criterion, nitrogen oxide (NOx), carbon oxide (CO) and carbon dioxide (CO2), the emission was studied. While the ignition delay was also studied with biodiesel blending ratio variation. The blending ratio of the biodiesel used were from 20% until 40%. The biodiesel used were algae, Jatropha and waste cooking oil. The finding reveals that the higher value of the ambient temperature mixture induces shorter ignition delay when the CVC and CC are coupled at different ambient temperatures. The emissions data obtained shows that the CO and HC component is lowered while the ambient temperature is higher but the volume of NOx rises. In the future, biofuels can be inferred as excellent fuel alternatives to replace diesel.
