Effects of Organic and Pyrolysis Fuel on Ignition and Combustion Process

Abstract

The worries about the limitation of fossil fuel and the advantages of alternative fuel has been raised all through the previous year. This research investigates the effects of organic and pyrolysis fuel on ignition and combustion process. Rapid compression machine (RCM) was used to simulate the engine combustion phenomenon in order to study its physical and chemical behaviour at specific fuel injection pressures and ambient temperatures. There are two types of fuel were used which is organic biodiesel derived from organic resources and pyrolysis fuel derived from Tyre Pyrolysis fuel (TPO). There are few samples of organic fuel prepared for this experiment which is Crude Palm Oil (CPO), Waste Cooking Oil (WCO), Jatropha (JO) and Algae (A) that injected directly into the combustion chamber. In this research, CPO 10 composed of 10% of crude palm oil and 90% of biodiesel were injected directly into the combustion chamber. Fuel injection pressure is varied between 90 MPa and 130 MPa under variant ambient temperature of 750 K, 850 K 950 K. The results show that higher fuel injection pressure, shorter ignition delay and more obviously for CPO compared than TPO and organic biodiesel. In addition, increased ambient temperature, the ignition delay became shorter as all the fuels tested shows a similar trend. © 2022, Universiti Malaysia Perlis. All rights reserved.
