An Observation of Combustion Phenomenon on Heat Insulated Turbo-Charged and Inter-Cooled D.I. Diesel Engines 861187
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.
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).
The effect of higher combustion temperature on the combustion phenomena is discussed.
