Experimental study of exhaust emissions and performance of a dual fuel IDI diesel engine
Published 1999“…The admission of more gaseous fuel with the intake air increased the engine power, thermal efficiency, and NOx emissions while CO and UHC emissions increased up to the flame initiation limit beyond which they decreased sharply. The experimental results showed higher engine powers and efficiencies, lower CO and UHC emissions, and unfortunately higher NOx emissions and narrower knock-free operating range with employing larger pilot fuel quantifies, advancing the pilot fuel injection timing, and increasing the intake temperature. …”
