Comparison of Performance and Emission of a Gasoline Engine Fuelled by Gasoline and CNG Under Various Throttle Positions

Saad Aljamali, Wan Mohd Faizal Wan Mahmood, Shahrir Abdullah and Yusoff Ali

Abstract:
This study presents comparison of performance and emission of a gasoline engine fuelled by gasoline and CNG under various throttle positions by test results from running 1596 cm3, 4-cylinder spark-ignited gasoline port injection. CNG is considered as a popular alternative fuel and many studies focus on this field. Performance and emission measurements were recorded under steady-state operating conditions using an engine control system and the portable exhaust gas analyzer. The engine was run at (50, 100%) throttle position, 100% engine load and speed ranging from 1000 revolutions per min (rpm) to 6000 rpm with 500 rpm increments. Results show gasoline is more power, torque and Brake Mean Effective Pressure (BMEP) than CNG but Brake Specific Fuel Consumption (BSFC) of gasoline is not as much as CNG. Furthermore it shows to a smaller extent carbon dioxide (CO2) and carbon monoxide (CO) in CNG compared to gasoline. Nitric Oxide (NO) and Mono-Nitrogen Oxides (NOx) emission for CNG is less than gasoline.
