【Abstract】 A 490Q D. I. diesel engine was refitted into a diesel/CNG dual fuel engine, which could work using the dual fuel in substitution of 80% natural gas for diesel. The experimental studies on the engine running fueled by pure diesel and diesel/CNG dual fuel respectively were carried out. The performance characteristics of the dual fuel engine fueled by diesel and dual fuel respectively were compared on their engine power, fuel consumption, emission and noise.更多还原
