Abstract :
Experiments have been conducted to analyse emission performance of different rate of fumigation of two
different light fuels. To implement better method to reduce the diesel emission using various methods like thermal
barrier coating along with exhaust gas recirculation and with fumigation with diesel blends with 1,4 dioxane. Base
data is recorded with base diesel fuel with and without PSZ Zirconium thermal coating. NOx emissions can be
substantially reduced in fumigation with both the fuels. Carbon monoxide emission increased in fumigation mode.
Smoke emission is considerably reduced at high loading conditions for fumigated fuel and the reduction is high for
MEK fumigation compared with methanol the performance, emissions and combustion characteristics of the engine
under variable load conditions have been compared for the optimum blends with diesel, for the engine with PSZ
Zirconium coating and with EGR. Results shows that improved performance with blends compared to base diesel
fuel for all loading conditions. However, 70% diesel, 20% ethanol and 10% dioxane blends show 36.4% of brake
thermal efficiency without coating and 38.5% with PSZ Zirconium coating compared with 31% for the base diesel
fuel.
