Summary:

The present work deals with statistical optimization of adirect-injection diesel engine. Due to the NOX and particulatetradeoff relation in diesel engines it is difficult to reduce thesetwo pollutants simultaneously. Previous studies have indicated theeffects of inlet air components and injection nozzle openingpressure on NOX and particulate emissions.The objective of this study was to find the optimized operatingparameters point for a single-cylinder DI diesel engine at 1500 rpmand 75% load to reach a desired NOX, smoke and fuel efficiencylevels, using a Response Surface Method (RSM). The operatingparameters used in the optimization process are inlet air CO₂%(simulation of EGR) and injection nozzle opening pressure. Amathematical statement of goal was defined in the form of anobjective function.It was shown that RSM is an effective method to obtain theoptimum operating parameters point. RSM optimization resulted insimultaneous reduction in NOX and particulate emissions withoutsacrificing fuel efficiency. Effects of operating parameters onemissions were noted and discussed in the process ofoptimization
