RATE OF NITROUS OXIDE FORMATION IN THE DIESEL PROCESS WITH DIRECT INJECTION

GESCHWINDIGKEIT DER STICKOXIDBILDUNG IM DIESELPROZESS MIT DIREKTER EINSPRITZUNG

The tests have demonstrated that an increase in the ignition lag results in a directly proportional increase in the speed of nitrous oxide formation. As regards the influence of the air conditions, it was established that with fuel-rich mixtures, the nitrous oxide formation at higher combustion chamber temperatures was slower than in the case of weaker mixtures with correspondingly lower combustion chamber temperatures. The oxygen deficiency influenced the probability of reactions between the oxygen and the nitrogen. It was not possible to find a relation between air conditions and ignition delay. The velocity of nitrous oxide formation decreased sharply with the temperature of the combustion chamber wall. In the measured areas, a decrease in the nitrous oxide formation speed was found with increased compression ratios. Overall, an effective reduction in the nitrous oxide emission from direct injection diesel engines may be expected from all measures which involve a reduction in the ignition lag. /TRRL/
