Abstract
Measurements are made of specific fuel consumption, thermal efficiency and ignition delay, together with exhaust emissions of oxides of nitrogen, carbon monoxide and dioxide and smoke. The results exhibit trends similar to those reported for single-cylinder engine work in relation to use of vegetable oil and emulsification. Highest thermal efficiencies were recorded for vegetable oil and its 10 per cent emulsion with water at 2500 and 3500 r/min at maximum load and lowest smoke and oxides of nitrogen levels were measured for the vegetable oil emulsion at both speeds. Emulsification influenced the smoke- nitrogen oxides trade-off.
