Combustion Analysis on HCCI Engine By Using Blended Fuel With Varying Injection Timing Of PCCI

Abstract

There are two sorts of inside burning motors in particular the sparkle ignition (SI) and the pressure ignition (CI). Petrol and diesel are at present rule powers for SI and CI motors. These energizes are very nearly getting wiped out. The fuel oxidation process in the motor produces valuable force, as well as a lot of poison outflows including carbon dioxide (CO2), carbon monoxide (CO), unburned hydrocarbon (HC), nitrogen oxides (NOx), and particulate matter (PM).

HCCI (Homogeneous Charge Compression Ignition) is a clean and efficient combustion process. In this project work an attempt is made to experimentally analyze the combustion characteristics of the HCCI compression process in a PCCI (Premixed Charge Compression Ignition) mode assisted with pilot injection (PI). Pilot Injector is an injector which is placed at inlet manifold. Here we used B30 (700 ml of diesel+ 300 ml of bio diesel) as a secondary fuel and diesel as primary fuel. By changing the injection timing of the PCCI mode at 20^o,40^o,60^o of the crank angle we have done an experiment and analyzed exhaust gases compared to conventional CI engine and also seen efficiencies of both HCCI and CI engines
