Decrement of toxic emission from direct injection engine by using animal fat biodiesel and cooled-exhaust gas recirculation system
This investigation presents the experimental results of a direct injection engine running on lard BD (biodiesel) blends and running on commercial diesel fuel by the cooled EGR (exhaust gas recirculation) method and evaluates the overall performance and exhaust emission characteristics of the engine under various engine operations. Moreover, the direct effect of the properties of the lard BD blends on the particle size distribution of the exhaust smoke emission after burning of the injected fuel was investigated by SEM analysis. Particle size reduced significantly with the lard BD blends, which can be attributed to the more complete combustion of lard BD blends than diesel fuel. Engine performance reduced slightly with EGR due to the lower calorific values of the lard BD blends; but thermal efficiency was not affected significantly. NOx evidently decreased with use of lard BD blends with EGR. The NOx reduction rate was much higher than the smoke increase rate with EGR. The optimal EGR region was found for every lard BD blend using the data on the simultaneous reduction of NOx and smoke.
