| Abstract | ||
| The experiment was conducted at Heat Laboratory - College of Engineering - University of Baghdad during 2013. Three local diesel fuel included Baiji, Daura, Basrah. Five levels of engine speeds included 2000, 2250, 2500, 2750, 3000 RPM and five levels of loads included 2, 4, 6, 8, 10 Nm were used in this study. This study repeated in winter season in January under 13°C and in summer season in July under 39°C. The tests of this research were carried out on four stroke diesel engines to evaluate the effect of winter and summer season on diesel engine performance parameters by using different types of local fuel under different speed and loads. The experiment was executed according to a split split plots design under Randomized Complete Design (RCD) with three replications. Least significant differences (L.S.D) were used to compare means of treatments at 0.05 level. Performance parameters of engine were studied in this experiment are specific fuel consumption, indicated power, exhaust temperature, volumetric efficiency. The results obtained reveals lowest specific fuel consumption was in Daura fuel in summer. Better indicated power was in Daura fuel in summer. Lowest temperature was in Daura fuel in summer. Best volumetric efficiency was in Daura fuel in winter. Lowest specific fuel consumption was in Daura fuel at 2750 RPM in summer. Better indicated power was in Daura fuel at 3000 RPM in summer. Lowest temperature was in Daura fuel at 2000 RPM in summer. Best volumetric efficiency was in Daura fuel at 2000 RPM in winter. Lowest specific fuel consumption was in Daura fuel at 10 Nm in summer. Better indicated power was in Daura fuel at 10 Nm in summer. Lowest temperature was in Daura fuel at 2 Nm in summer. Best volumetric efficiency was in Daura fuel at 2 Nm in winter. Lowest rate of specific fuel consumption was in Daura fuels at 2750 RPM, at 10 Nm in summer. Highest rate of indicated power was in Daura fuel at 3000 RPM at 10 Nm in summer. Lowest ratio of temperature was in Daura fuels at 2000 RPM at 2 Nm in summer. Highest rate of volumetric efficiency was in Daura fuel at 2000 RPM at 2 Nm in winter. | ||
