This paper presents work conducted at the Universiti Kebangsaan Malaysia to support of 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 using for HCCI engine fuel was investigated in vibration signal using RIONOTE hardware and Mathlab (I-kaz Vibro). Percentage of blend of Palm Oil Methyl Ester and RON 97 based on 0%, 5%, 10%, 20%, and 30% percentage blended. Result will be showed in comparison between blended fuel to power, torque, and fuel consumption (measured by dynamometer) with vibration signal produce during HCCI combustion. Conclusion of experiment analysing vibration signal will show the experimental plan is feasible and reasonable.
