HCCI Technology: Operating Principles, Advantages, Challenges, and Future Prospects

Abstract

In recent years, with the development and research on internal combustion engines, human beings have gained a deeper understanding of the combustion mechanisms and properties of traditional spark ignition (SI) and compression ignition (CI) engines. It has also been discovered that these two distinct types of engines each have their advantages and drawbacks. This is why there has been a growing emphasis on the research and experimental analysis of homogeneous charge compression ignition (HCCI) engines in recent times. This is because achieving high thermal efficiency while maintaining extremely low hydrocarbon (HC) and carbon monoxide (CO) emissions positions it as one of the potential engine technologies to address recent environmental and energy challenges. The article also discusses the difference in emissions when using different fuels for HCCI engines, such as diesel, petrol, and liquefied petroleum gas. Meanwhile, the last part concludes with a description of a stationary application that employs HCCI technology for power generation. This article will introduce the working principles of HCCI engines, the advantages and disadvantages of the HCCI process, and some solutions to its drawbacks. At the end, an application of HCCI technology for power generation and its related information will be presented.
