A Study on Alternative Fuel Blending for Homogeneous Charge Compression Ignition (HCCI) Engine Using Palm Oil Methyl Ester and RON 97

Abstract

This paper presents work conducted at the Universiti Kebangsaan Malaysia to support the HCCI Engine Program. The objective of this paper is to develop an engine that employs Homogeneous Charge Compression Ignition (HCCI) combustion and features using Palm Oil Methyl ester as fuel. A Novel of palm oil product usage for HCCI engine fuel was investigated. Different percentage of blend of Palm Oil Methyl Ester and RON 97 was tested using Digital Boom Calorimeter. An experiment based on 0%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100% percentage blending between Palm Oil Methyl Ester and RON 97 produced results with an average of 39 MJ/g. Result shows that a high percentage blending of methyl ester with Ron 97 will increase the calorific value of fuel and this result also shows that a low pressure needed to ignite combustion in combustion chamber because of the high calorific value.
