Improvement of Horse Power and Specific Fuel Consumption in Diesel Engine:Technical Note

The output performance characteristics of the engine used in Tillers is based on the various factors such as discharge of the pump, nozzle, and dimensions of rocker arm, rocker screw, adjusting crank case, gear case, timing gears, piston, piston rings and cylinder head. The objective of the work is to get the optimum solution for getting the increased Horse Power (HP) and Specific Fuel Consumption (SFC) of the engine based on maintaining the mentioned components dimensions in close tolerance in addition to process wise monitoring during assembly and engine testing. During engine testing, the pump discharge is adjusted by the fuel adjuster and the tolerance limits are kept closer to the actual value to obtain the required HP and SFC.
