Parametric Optimization of Single Cylinder CI Engine Fuel with Diesel-Waste Plastic Oil Blend

Abstract

In this study, a Taguchi’s method is used to determine the optimal combinations of compression ratio, injection
pressure, blend ratio and load of a diesel engine fueled with diesel-biodiesel blend. The previous researchers had done
research on combined effect of compression ratio and blend ratio but in this research. Experiments has been carried out
using various sets of parameters like compression ratio, injection pressure and engine output. The optimum results for
selected responses are achieved with optimum sets of parameters. Peak pressure of the cylinder is also measured and
optimized within all set of experiments. The optimum set achieved from experiments for SFC is with 16 compression ratio,
100D0B blend, low injection pressure (160 bar) at 12 kg of load. The optimum set achieved from experiment for Brake
Thermal Efficiency from experiments is with 16 compression ratio, 100D0B blend, low injection pressure (160 bar) at 12 kg
of load. The optimum set achieved from experiment for peak pressure from experiments is with16 compression ratio, 100D0B
blend, low injection pressure (160 bar) at 12 kg of load. At the end, the experiments are carried out using optimum set of
parameters in order to validate the optimum predicted results. Experiment results shows that predicted values by Taguchi’s
method are closer to the experiment values. Taguchi’s method gives accurate results with less number of experiments.
