Abstract

In this study, the combustion and emission characteristics of waste cooking oil biodiesel was investigated. The fuel was injected from 5 CAD (Crank angle degree) ATDC (After top dead center) to -60 CAD ATDC by 5 CAD with 800 bar and 1600 bar injection pressure. Generally, the hydrocarbon, carbon monoxide and smoke emissions from biodiesel fuel were lower than the emission levels of diesel fuel. However, the emission characteristic of biodiesel got worse than diesel when the fuel was injected earlier than -30 CAD ATDC. $NO_x$ emission from biodeisel was higher than diesel fuel in all experimental conditions.
