Experimental Investigation of a 4-Stroke Diesel Engine for Varying Fuel Injection Pressure and Compression Ratio

A.D. Badgujar

Abstract


Diesel engines are widely used in transportation, agriculture, power sector and various other types of industries due to its high fuel efficiency. An improvement in the performance of the same makes remarkable difference in nation economy. This paper presents an experimental investigation of a 4-stroke engine, using diesel as a fuel. The engine is modified to study the effect of various parameters on the performance of engine. The parameters varied are; fuel injection pressure and compression ratio. The fuel injection pressure is measured using piezoresistive sensors and is varied from 224 to 240 bar. The compression ratio is varied from 16 to 18 by changing the clearance volume. It has been experimentally observed that as the fuel injection pressure increases, the efficiency of the engine decreases and as the compression ratio increases, the efficiency of the engine increases.
