Biodiesel is a well recognized choice for diesel and has an benefit over the later because of it is renewable, biodegradable, sulphur free and non-less poisonous in nature, better lubricity and can considerably reduce exhaust emissions from the engine. This study investigates the use of ethanol as an additive with 20% pungai oil diesel blend (B20). The transesterification process is used to reduce the viscosity of the pungai oil. The main aim of this paper is to examine the emission parameters of variable injection pressure diesel engine runes with pungai oil 20% (B20) and ethanol as a additive by adding 5% and 10% at steady speed of 1500 rpm with variable loads and changeable injection pressure (180,210&240). The outcomes of these blends are to be compared with normal diesel. The fitness of pungai oil with ethanol is established as a bio fuel in this study. The impact of pressure injection on exhaust gas emissions has been investigated and offered. The exhaust emissions Hydrocarbons, Carbon monoxide and carbon dioxide are are almost reduced compared to diesel. Brake power, indicated power, brake thermal efficiency, mechanical efficiency, mechanical efficiency, brake mean effective pressure, are investigated on performance characteristics.
