Effect of Turbo charging On Volumetric Efficiency in an Insulated Di Diesel Engine For Improved Performance
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 2
Abstract
Abstract: The world’s rapidly dwindling petroleum supplies, their raising cost and the growing danger of environmental pollution from these fuels have led to an intensive search for an alternative fuels with concerned efforts to conserve the oil reserves. Among all the fuels, tested alcohol is proved best alternatives to the petroleum fuels because all these are derived from indigenous sources and are renewable. However, with the alcohols higher latent heat of vaporization and lower cetane number, the Insulated engine (IE) is used for the combustion in the diesel engines. The higher temperature in the combustion chamber decreases the ignition delay and aids combustion but drops the volumetric efficiency. The degree of degradation of volumetric efficiency depends on the temperatures in the combustion chamber and it further increases the frictional horsepower due to thinning of lubricant. Therefore, for improving the thermal efficiency of insulated engine, the volumetric efficiency drop is compensated by turbo charging in the present experimental work. This gave the better performance with reduction in smoke. With theturbo, charging the intake boost pressure is raised and its effect on the engine performance is also studied.
