EFFECTS OF INJECTION TIMING AND EXHAUST GAS RECIRCULATION ON EMISSIONS FROM A D. I. DIESEL ENGINE

Some results of a systematic study of the effects of injection timing retard and exhaust gas recirculation on emissions from a D. I. diesel engine are presented. The factors investigated include engine speed, fuel rate, injection timing, injection pressure, intake charge oxygen concentration, and type of diluent. The detailed mechanisms governing the formation and control of nitric oxide were studied analytically, using a previously developed diesel combustion model based on transient fuel-air mixing and Zeldovich nitric oxide reaction mechanism.
