Effect of Intake Air Temperature on Performance and Emissions of Diesel Fueled Engine

Abstract

To determine the effect of intake air temperature on emissions of a diesel engine, a study consists of intake air at variable temperature. The Experiment was conducted on direct injection fuel, four cylinders, Experimental engine connected to gas analyzer. The experimental results show that there was a significant relation of the intake air temperature with performance of the engine. Increasing the intake air temperature HC, CO, NOX and CO2, are increase. Impact of intake air is noticeable when temperature of air is high such as 77ºc.
