Abstract
The present work deals with statistical optimization of a
direct-injection diesel engine. Due to the NOX and particulate
tradeoff relation in diesel engines it is difficult to reduce these
two pollutants simultaneously. Previous studies have indicated the
effects of inlet air components and injection nozzle opening
pressure on NOX and particulate emissions.
The objective of this study was to find the optimized operating
parameters point for a single-cylinder DI diesel engine at 1500 rpm
and 75% load to reach a desired NOX, smoke and fuel efficiency
levels, using a Response Surface Method (RSM). The operating
parameters used in the optimization process are inlet air CO₂%
(simulation of EGR) and injection nozzle opening pressure. A
mathematical statement of goal was defined in the form of an
objective function.
It was shown that RSM is an effective method to obtain the
optimum operating parameters point. RSM optimization resulted in
simultaneous reduction in NOX and particulate emissions without
sacrificing fuel efficiency. Effects of operating parameters on
emissions were noted and discussed in the process of
optimization.
