Abstract
In future demand for fossil fuels and environmental effects, a number of renewable sources of energy has been studied in worldwide. An attempt is made to apt of vegetable oil for diesel engine operation, without any change in its old construction. One of the important factors which influence the performance and emission characteristics of D.I diesel engine is fuel injection pressure. In this project honne oil has to be investigated in a constant speed, on D.I diesel engine with different fuel injection pressures.
The scope of the project is to investigate the effect of injection pressures on a blend of 50% honne oil with 50% diesel and compare with pure diesel on performance and emission characteristics of the diesel engine. Two tested fuels were used during experiments like 100 % diesel and a blend of 50% honne oil mixing in the diesel. The performance tests were conducted at constant speed with variable loads.
From experiment results it was found that with honne oil- diesel blend the performance of the engine is better compared with diesel. The break thermal efficiency and mechanical efficiencies were found to be maximum at 200 bar injection pressure with both honne oil- diesel blend, compared with 180 bar and 220 bar. The brake specific fuel consumption was to be minimum at 220bar compared with 180 bar and 200 bar. Hydro carbon emissions of honne oil-diesel operation were less than the diesel fuel mode at all fuel injection pressures.
