Abstract

Increasingly stringent emissions and fuel economy standards have long remained challenges for research in
automobile engine technology development towards the more thermally efficient and less polluting engine. Increasing the
consumption of fuel in power and automobile sector, increase the pollution of the environment. Smoke and NOX are
main pollutants of emission from diesel engine and it is very difficult to control them simultaneously Petroleum based
fuels is a finite resource that is rapidly depleting. An experimental investigation is carried out to study the effect of
compression ratio on variable compression ratio engine using diesel oil. In this paper the performance characteristics
are studied at various compression ratios. Better combustion and better utilization of fuel at compression ratio 16.So
Smoke density is less for CR 16 which is the optimum compression ratio for this engine. Carbon monoxide emission is
lower at CR 18 and highest at CR 14. At CR 16 the value of CO emission is moderate. Hydro carbon emission is lower at
CR 18 and highest at CR 14.At CR 16 the value of HC emission is moderate. For this engine optimum compression ratio
is 16.
