【 摘 要 】

SI and CI engines are entities in which conditions of internal combustion was triumphantly implemented. In a gasoline engine both efficiency and emissions are less; on the other hand in a diesel engine both are relatively high. It is hard to achieve a win-win situation where fuel consumption and adverse impact on the environment were diminished. Over the past few decades researchers have assigned themselves to strike a balance in this regard, creating Homogeneous charge compression ignition engine technology, which perfectly amalgamates the principles of Spark Ignition and Compression Ignition engines, making it the holy grail of engines. Homogeneous charge compression ignition engines do not employ spark plug or fuel injector to initiate combustion, the lean homogeneous mixture auto-ignites in multitudinous spots once it is compressed to attain its chemical activation energy. Unlike its contemporaries the combustion is flameless, propelled the fuel efficiency along with an enormous decrease in emissions. This proposed work digs deep into conceptual description of the fundamentals of HCCI engine and various approaches to attain HCCI, along with the challenges encountered related to the same being elaborated. Depending on inferences arrived from the challenges different controlling strategies are proposed in this paper.
