The Performance and Analysis of a Diesel Engine by Using Bio-Diesel as Fuel and By Using Five Different Types of Pistons.

Abstract

as a renewable, sustainable and alternative fuel for compression ignition engine, biodiesel instead of diesel has been increasingly fuelled to study its effects on engine performances and emissions in the recent 15 years. Biodiesel, derived from the transesterification of vegetable oils or animal fats, is composed of saturated and unsaturated long-chain fatty acid alkyl esters. The aim of the present paper is to do a comprehensive review of engine performance and emissions using biodiesel from different feedstock and to compare that with the diesel. From the review it is found that the use of biodiesel leads to the substantial reduction in HC and CO emissions accompanying with the imperceptible power loss, the increase in fuel consumption and the increase in NO_x emission on conventional diesel engine with no or fewer modification. However, many further researches about modification on engine, low temperature performance of engine, new instrumentation and methodology for measurements, etc., are recommended while using biodiesel as a substitute of diesel. In this project we are going to perform and analyze the mechanical efficiency brake thermal efficiency and volumetric efficiency and also reducing the pollutant contents like CO, NO_x, CO₂ and Chlorofluorocarbons’. By using sunflower oil as bio-diesel and also by using five different types of piston.
