The Application of HCCI Technology in the Automotive Industry: Technical Analysis and Future Prospects with Mazda as an Example

Homogeneous Compression Combustion Ignition (HCCI) engine is a new type of combustion engine technology that realizes fuel combustion through compression ignition. It combines the benefits of gasoline and diesel engines to improve fuel efficiency and reduce emissions significantly. Its huge advantage of improving efficiency is widely used in the automotive field. This paper summarizes the achievements and challenges of HCCI engines and their application in automotive industries especially in Mazda. Mazda uses its SkyActiv-X engine to produce the car model to achieve high efficiency and low emissions. Another company, General Motors, has its own Ecotec engine to ensure the stability of combustion conditions, thus applying the HCCI technology. HCCI technology faces challenges such as ignition control and stable combustion conditions, but through continuous technological innovation and optimization, HCCI is expected to become one of the mainstream internal combustion engine technologies in the future. It solved the problem of high efficiency and being environmentally friendly, which could help the global warming caused by too much fossil fuel use.
