Effect of Compression Ratio on Performance and Emissions of a Single Cylinder Four Stroke Diesel Engine: Impact of Compression Ratio on Performance and Emissions of a Single Cylinder Four Stroke Diesel Engine

Abstract

Experimental work was conducted to evaluate the effect of compression ratio on performance and emission by using conventional diesel fuel on the single cylinder four stroke variable compression ratio (VCR) engine. The compression ratio is a factor that influences the performance characteristics of an internal combustion engines. This work is an experimental investigation of the influence of the compression ratio on brake thermal efficiency, specific fuel consumption, and Exhaust Gas Temperature (EGT) with emission HC, CO & NOx. of the Kirloskar variable compression ratio duel fuel engine. Compression Ratios of 16, 17, 18, 19 and 20 and engine loads of 0 kg to 10 kg, with increments of 2kg, were utilized for Diesel Engine. The tests were performed at 1500 rpm engine speed and emissions were measured by AVL emission 5 gas analyser.
