Abstract

This paper deals with the systematic study of  performance evalaution and exhaust emission characteristics of  VCR (variable compression ratio) engine at different compression ratio and loads using diesel as fuel. Experimental analysis was done to find the optimal value of compression ratio and load at which the engine can produce higher thermal efficiency, lower specific fuel consumption and low exhaust emission. Performance parameters such as brake mean effective pressure (BMEP), brake thermal efficiency (ɳbth), brake Specific fuel consumption (BSFC), and  exhaust gas emissions like hydrocarbon, carbon monoxide and nitrogen monoxide are considered.
