ABSTRACT
In recent times, homogeneous combustion has been a proven technology to attain high efficient and low emission engines. Homogenous Charge Compression Ignition (HCCI) engines are able to have efficiencies as high as Compression Ignition, Direct Injection (CIDI) engines, while producing ultra-low emissions of nitrogen oxides (NOx) and particulate matter (PM).HCCI combustion is achieved by controlling the temperature, pressure and composition of the fuel-air mixture so that it spontaneously gets ignited in the combustion chamber. Numeroustechniques such as Variable Exhaust Gas Recirculation (VEGR), ariable Compression Ratio (VCR) and Variable Valve Timing (VVT) have been proposed to control the homogeneous combustion inside the engine cylinder. Even though these techniques are attractive and having good time response, they are too expensive to afford. This paper investigates the performance, combustion and emission characteristics of a Direct Injection (DI) diesel engine under HCCI mode which is established through an effective and affordable technique called Porous Medium Combustion (PMC).
