Effect of Equivalence Ratio on ITM 285 Tractor engine performance at nominal rpm
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 15
Abstract
In this research work, one of the most widely used agricultural diesel engines (scientific name of 4.248G) placed on ITM 285 tractor is analyzed experimentally. This paper focuses on the effect of equivalence ratio on this engine performance parameters at nominal rpm )Speed of 2000 rpm). Equivalence Ratio was varied from =0.197 to =1.23 at speed of 2000 rpm. From the acquired results show that the equivalence ratio was greatly influences on the engine performance. It was shown that by increasing the equivalence ratio, the output power and mean effective pressure in the cylinder at first increases and then decreases. The lowest brake specific fuel consumption occurs at equivalent ratio ≅0.7. Maximum Brake thermal efficiency was obtained equal to 31.45% and a significant relationship was not found between equivalence ratio and volumetric efficiency. The results obtained in this study can be used to optimize 4.248G diesel engine performance at nominal rpm.
