Abstract
Road load performance parameters and exhaust emissions have been measured for a 2.0 litre Ford (OHC) engine fitted with a Rajay 300 series turbocharger, on a test-bed-simulated (European) ECE-15 urban driving cycle. Results obtained with a 4 * premium leaded gasoline have been compared with those obtained with neat methanol and an octane boosted unleaded gasoline. The fuel consumption was found to be higher with methanol because of its lower combustion enthalpy than with the gasoline fuels tested, but engine stability was maintained over a wider range of air-fuel ratios and exhaust emissions were lower. A comparison with results obtained under naturally aspirated conditions has also been made.
