Abstract
This project is to study the ignition mechanism of low and high octane number of fuel blends through comprehensive simulation. Homogenous Charge Compression Ignition (HCCI) is an alternative combustion concept for in reciprocating engines which offers significant benefits in terms of its high efficiency and low emissions. HCCI is the most commonly used name for the auto-ignition of various fuels and one of the most promising alternatives to SI combustion and CI combustion. The objectives of this project is to study reaction mechanism of compression ignition at Low Temperature Oxidation (LTO) and design the simplified model of reaction mechanism for n-heptane + toluene (NTF). Low Temperature Oxidation (LTO) define as oxidation at temperatures near or below 25℃. The low temperature oxidation mechanisms of n-heptane have been extensively studied in recent and past literature because of its importance as a primary reference fuel. In this study, n-heptane as a base fuel and toluene as a sub fuel, will use as a fuel mixture in this simulation. Moreover, for numerical analysis, to design simplified model of reaction mechanism for n-heptane supported by MATLAB software. The simplified model has been discussed in this project. The significant result of this project, it can observed that the increasing of toluene content can caused the reaction of aldehyde group and OH reproduction. Finally, thesis conclude that the simplified model constructed with a consideration of the property of reaction happen in n-heptane (base fuel) added with toluene (sub fuel) in which OH reproduction and fuel + OH reaction plays important role.
