P. Belardini et al., COMBUSTION AND POLLUTANT EMISSIONS FROM LIGHT DUTY DIESEL-ENGINES - THE INFLUENCE OF MIXING PROCESS AND TRANSIENT OPERATING-CONDITIONS, Science of the total environment, 134(1-3), 1993, pp. 285-293
The influences of transient operating conditions and mixing process on
exhaust emissions of the direct injection (DI) diesel combustion syst
em are pointed out. With the use of a transient dynamic facility the c
ombustion process was characterized and the combustion parameters were
employed in order to explain the emission behaviour of the engine. Wi
th the joint use of three dimensional modeling and field experiments t
wo different combustion system were compared and the emission behaviou
r was fully explained. Finally a mixing parameter was defined allowing
a more useful use of 3-D calculations to the design of the combustion
system.
