CONTROLLING EXHAUST EMISSION FROM THE TURBOCHARGED AUTOMOTIVE DIESEL ENGINE

The result of the low emission combustion tuning for the turbocharged-aftercooled diesel engine will be described in this paper. A good mixing of the induced air and the injected fuel in the cylinder was obtained with special design of the intake port. This new intake port features prevention of increase in black smoke when the injection timing is retarded for the purpose of low nitric oxide emission. The intake port was applied to the naturally aspirated and the turbocharged-aftercooled engines. In the former engine, an effect of prevention of increase in black smoke together with low fuel consumption was obtained. But when the new intake port was applied to the turbocharged-aftercooled engine, despite less smoke and low exhaust emission, it showed higher fuel consumption than the naturally aspirated engine. Test results and consideration for the improvement of smoke and exhaust emission levels additionally with thermodynamic analysis on the cause of increased fuel consumption are explained in this study. /TRRL/
