IMPROVEMENT OF THE EXHAUST EMISSION FROM DIRECT INJECTION DIESEL ENGINES BY LOAD-DEPENDENT CONTROL OF THE INJECTION WITH SPECIAL REFERENCE TO ECONOMIC ASPECTS

VERBESSERUNG DER ABGASEMISSION VON DIREKTEINSPRITZ-DIESELMOTOREN DURCH LASTABHANGIGE STEUERUNG DES EINSPRITZZEITPUNKTES UNTER BESONDERER BERUCKSICHTIGUNG DER WIRTSCHAFTLICHKEIT

Studies have proved that, after a corresponding adjustment, modern turbocharged direct-injection diesel engines are able to comply with the most stringent environmental demands in respect of visible and invisible emissions, while at the same time providing adequate power. If several standards have to be complied with at the same time, this is as a rule only possible at the expense of fuel economy. Particular attention should be paid to the fact that in order to attain the given limits (EEC and California) different ways and means can be used for the same type of engine. The means of optimization should therefore always be chosen with a view to the intended application of the vehicle, in order to attain the highest possible degree of economy. Turbocharged engines are more flexible, particularly with regard to their smoke characteristics, since operation with a high amount of excess air leaves full scope for varying the injection timing without exceeding the specified smoke limits. /TRRL/
