Abstract

This study presents effects of advanced injection timing on engine performance and emission characteristics of a supercharged producer gas-diesel dual fuel diesel engine fueled by producer gas from a downdraft gasifier. Original injection timing of engine was 14° before top dead center (BTDC), and tests were conducted at advanced three different injection timings (17°, 20°, and 23°) by changing thickness of copper shim. Experiments were carried out at a constant injection pressure (2 bar) with varying injection flow rates of both producer gas and air at different engine speeds and loads. Advancing injection timing in a supercharged engine showed that diesel fuel displacement and brake thermal efficiency increased, with a significant reduction in carbon monoxide emission and specific energy consumption compared with original injection timing of premixed producer gasdiesel dual fuel.
