Abstract:

The effects of biodiesel blending fuels with different biodiesel fractions on the exhaust emission characteristics of the diesel engine were investigated on a heavyduty automotive electronically controlled highpressure commonrail diesel engine. Five diesel/biodiesel blends were tested according to ESC steadystate 13mode test cycle without modifications of engine construction and parameter adjustment. The test results showed that the brake specific emissions(BSEs) of CO, PM and DS decrease with the increase of biodiesel fraction in the blending fuel, while the BSEs of HC and SOF decrease a little, but the BSE of NOx increases gradually. Compared with BD(pure diesel) the 13mode weighted average BSEs of CO, PM and DS of fuel B30(30% biodiesel) decrease by 46.0%,27.5% and 44.2% respectively, while the BSE of NOx increases by 10.9%. The weighted BSEs of CO,PM and DS of biodiesel decrease more obviously under high load conditions.

Key words: power machinery and engineering, diesel engine, biodiesel fuel, exhaust emission, ESC 13-mode test cycle
