Performance Enhancement of Internal Combustion Engine Using Weight Reduction Approach

The purpose of this study is to investigate and enhance the performance of the single cylinder 4-stroke water cooled diesel engine using weight reduction approach. Initially, the existing engine of 3.7 kW (5 hp) was tested for performance analysis as per the method mentioned in IS 11170 for loop test by altering its speed then an engine was critically studied for weight reduction possibilities and modified accordingly. The modified engine has been tested again following the similar method. The various performance and emission parameters of both the engines at their most suitable speed were measured and compared. From the result, it was concluded that the modified engine shows better result from performance and emission aspects along with better mobility and convenience at a reduced cost. However, the modified engine needs strong base plate as a foundation because of little higher speed.
