| Abstract: | An experimental
study has been carried out to simultaneously optimize several diesel engine
designs and operating parameters for low exhaust emissions using Taguchi
method. A single cylinder (DPF make) diesel engine equipped with a high
pressure, cam driven mechanical injector has been used in this experiment. The
effects of changes in engine design/operating parameters–nozzle spray holes,
piston–to–head clearance, nozzle protrusion, injection control pressure, start
of injection timing and swirl level on diesel engine emissions have been
investigated at two engine operating conditions, i.e., 40% of maximum load and
80% of maximum load using Taguchi design of experiment methods. Emissions are
quantified and optimum parameter setting has been arrived. Measurement of
exhaust emissions for the optimized engine showed that CO, HC and smoke
emissions are significantly lower than those obtained for the baseline engine.
Taguchi method has been found to be a useful technique for the simultaneous
optimization of several engine parameters and also for predicting the effect of
various design parameters on diesel exhaust emissions. |
