Biodiesel is an alternative choice for diesel and have benefits over diesel because, it is renewable, biodegradable, sulfur free, and non-poisonous in nature and less exhaust emissions. The transesterification process is used to reduce the viscosity of the karanja oil. The aim of this paper is to examine the emission parameters under variable compression ratios (17 and 18) in a VCR diesel engine which runs using karanja oil 20% (B20) and ethanol as an additive by adding 5% and 10% at constant speed of 1500 rpm with variable loads. The outcomes of these blends have been compared with the normal diesel. The influences of compression ratios on exhaust gas emissions were investigated. The exhaust emissions, namely hydrocarbons, NOx, carbon monoxide and carbon dioxide are found to be reduced when compared with diesel.
