An Observation of Combustion Phenomenon on Heat Insulated Turbo-Charged and Inter-Cooled D.I. Diesel Engines

Abstract

<div class="htmlview paragraph">A current unmodified and modified engines with different amounts of thermal insulation have been used to generate data from which changes in bsfc, cooling loss, emissions, exhaust loss were determined.</div> <div class="htmlview paragraph">Since legislative requirement exists for allowable emission of NOx, fuel injection timing and other controllable factors were adjusted to maintain constant NOx emission except a test of influence on NOx emission according to the rate of heat insulation (adiabaticity).</div> <div class="htmlview paragraph">The effect of higher combustion temperature on the combustion phenomena is discussed. </div>
