A study was carried out on the influence of biodiesel fuel on a diesel engine's performance, exhaust emissions, combustion and fuel-injection processes. These tests were performed on a direct-injected diesel engine using standard D2 diesel and commercial 100% biodiesel fuels. The tests were carried out using both fuels, under the same conditions. The exhaust emissions and the engine performance were measured and compared. The in-cylinder pressure was also measured, and the heat-release-rate curves were computed by means of a zero-dimensional one-zone combustion model. Some macro-parameters of the combustion process were obtained from the heat-release-rate curves. The injection system was separated from the engine and tested on a special test bench. The quantity of injected fuel was measured, and the injection pressure and injector-needle lift-time history were measured. The injection-rate curves were then computed and some macro-parameters of the injection process were obtained and analysed.
