Abstract

Compressed Natural Gas (CNG) is a difficult fuel to use in a Homogenous Charge Compression Ignition (HCCI) engine because of high octane number, high auto-ignition temperature, and rapid heat release.These properties force CNG HCCI engines to use extreme levels of intake heating. The Homogeneous Charge Compression Ignition concept has the potential to meet the need for a high efficiency and low emission engine. Fluent is one of the promising operating tool in the computational fluid dynamics. In the present study the Computational Fluid dynamics (CFD) code FLUENT is used to model complex combustion phenomenon in homogeneous charge compression Ignition engine. The variation of various properties like the peak cylinder pressure, peak cylinder temperature at various crank angles, at different relative air fuel mixture inlet temperatures and with hemi spherical combustion chamber and toroidal bowl has been studied. It was found that heated inlet air fuel mixture enhance combustion, peak cylinder pressure, peak cylinder temperature and change peak pressure timing.
