Performance, Emission, Combustion, Compression Ratio, Injection Timing and Injection Pressure on a Single Cylinder CI engine Operated with Mahua Methyl Ester

The automobiles play an important role in the transport system. With an increase in population and living standard, the transport vehicles as well as car population is increasing day by day. In addition to this there is steep increase in the number of two wheelers during the last two decades. All these are increasing exhaust pollution and particularly in metros as density of these vehicles in metros are very high. Injection diesel engine fueled with diesel and Mahua methyl ester blend. The main pollutants contributed by I.C. engines are CO, NOX unburned and other particulate emissions. Other sources such as Electric power stations industrial and domestic fuel consumers also add pollution like NOX, SO2 and particulate matters. In addition to this, all fuel burning systems emit CO2 in large quantities and this is more concerned with the Green House Effect which is going to decide the health of earth. Comparison of performance was done for different values of compression ratio, injection pressure and injection timing to find best possible combination for operating engine with MOME. It is found that the combined compression ratio of 16.1, 17.2,18.4, 19.5,20.7 and 21.6 injection pressure of 170, 190, 210, 230, 250 and 270bar and injection timing of 19, 21, 23 25, 27, 29°bTDC increases the brake thermal efficiency.
