Study and Effect of Exhaust Gas Recirculation (EGR) on the Performance and Emission Characteristics of Compression Ignition Engine.

Abstract

In this study, the effect of the injection pressure of the injection characteristics, and combustion performance of a single cylinder, four-stroke, direct injection, has been diesel engine investigated naturally aspirated experimentally using methyl esters of canola oil (Ven) and mixed with diesel fuel. Tests were conducted for four different injection pressures (18, 20, 22 and 24 MPa) at a constant engine speed and different loads. The experimental results showed that the different exposure fuel injection, combustion and performance characteristics of different motor loads and pressure injection. The investigation showed the characteristics of fuel injection is used in its diesel resulted in the timing of the previous injections instead. The maximum cylinder pressure and the maximum rate of pressure rise and the maximum rate of fire is a little less to come and mixtures. Consumption of certain types of fuel and brake specific energy consumption between brake higher than that of diesel, while the brake thermal efficiency is generally lower than diesel fuel. Increasing injection pressure gave better results for the specific consumption of fuel and brake brake thermal efficiency compared to the initial injection pressure was reduced..
