Abstract

A study is conducted to investigate the fuel injection pressure effects on the performance and exhaust emissions of a naturally-aspirated, four-stroke, divided chamber diesel engine having a swirl-combustion chamber. The influence of injection pressure on fuel consumption, exhaust gas temperature, exhaust smokiness and exhaust gas emissions (nitrogen oxides and hydrocarbons) is examined, following a detailed experimental investigation. It is shown that there is a significant variation of the above parameters with injection pressure, while keeping constant the static injection timing, engine speed and load. Theoretical aspects of diesel spray formation (atomization, evaporation and mixing) and combustion are used to explain the observed engine behaviour and provide insight into the mechanisms influencing the engine characteristics.
