Emissions Analysis of Preheated Methyl Ester on CI Engine

Abstract

Numerous research works are carried out to find out the additional information on effective use of vegetable oil in CI engine as a potential alternative fuel. The present work was intended to observe the outcome of preheating the transesterified oil earlier to fuel injection system thus making its properties similar to diesel. In this research mustard oil methyl ester was preheated to 90°c (MME90) and used in compression ignition engine and compared with mustard oil methyl ester (MME) fuelled at ambient temperature and diesel. The impacts of fuel preheating on engine emission with mustard oil were analyzed. Experiments were conducted with MME90 (Mustard oil methyl ester preheated to 90° C) and MME (Mustard oil methyl ester) and compared with diesel. Result confirmed increase in NOx emission for both MME90 and MME comparing diesel. Emissions such as CO, HC and Smoke were found in declining fashion for MME90 comparing MME and petroleum diesel. Preheating the mustard oil methyl ester during the fuel injection can be an exceptional way for using it in CI engines.
