Compressed Natural Gas Operated Two-Wheeler

In this paper the results obtained on a 110cc two-wheeler S.I. engine using both petrol and CNG as fuel. Tests like Acceleration test, Emission test, Mileage test and Exhaust noise test were conducted at different operating condition. The basic petrol engine is converted into a bi-fuel engine and regulated by means of an electronically controlled Solenoid Actuated Valve system. On a comparative analysis CNG fuelled engine accelerated slower compared to petrol fuelled engine, but the CO and CO2 emissions were lesser indicated that CNG when used as fuel accelerates at a faster rate, the emission of hazardous gases is comparatively far lower than petrol, fuel consumption of CNG is less and it is economical. The noise test shows that the exhaust of CNG is louder as compared to petrol.
