Abstract :

Homogenous charge Combustion ignition (HCCI) engines are being considered as an alternative to diesel engines. The HCCI concept involves premixing fuel and air prior to induction in to the cylinder (as is done in current spark- ignition engine) then igniting the fuel –air mixture through the compression process ( as is done in current diesel engines). The combustion occurring in HCCI engine is fundamentally different from a spark ignition and Diesel engines in that of heat release occurs as a global auto ignition process, as opposed to the turbulent flame propagation or mixing controlled combustion used in current engines . The advantage of this global auto ignition is that the temperature within the cylinder are uniformly low, yielding very low emission of oxides of Nitrogen( NOx, the chief precursors to photochemical smog). The inherent feature of HCCI combustion allows for design of engines with efficiency comparable to, or potentially higher than, diesel engines. This paper describes the results & Strategy proposed to control the combustion of HCCI engine. This is achieved by controlling air path & fuel path to maintain start of Combustion. An experimental results of Combustion Control analysis are presented to prove the strategy used for these experiments.
