In 2017, Mazda announced "Sustainable Zoom-Zoom 2030", focuses on three areas - "Earth", "Society" and "People" and sets out how we will use "driving pleasure", the fundamental appeal of the automobile, to create a sustainable future in which People and cars can coexist with a bountiful beautiful Earth.
A next-generation technology that take the internal combustion engine to a whole new level - SKYACTIV-X engine combines the advantages of gasoline and diesel engines, using the innovating Spark Controlled Compression Ignition (SPCCI), which embodies a high compression ratio of 15:1 and compression ignition technologies, together with the Mazda M Hybrid system to achieve better fuel economy and driving performance.
SPCCI Technology offers complete control of compression ignition (CI) combustion by way of spark ignition (SI). Firstly, the piston compression stroke brings the temperature of air-fuel mixture to the point just below that at which CI occurs. Then, a small spark is lit and generates a fireball in the center of the combustion chamber, which then creates heat and pressure wave and acts to further increase compression in the combustion chamber. This expanding fireball acts like a "variable secondary piston" further compressing the air-fuel mixture, providing the optimum temperature and pressure time after time on demand for compression ignition, resulting better performance and fewer emissions than a conventional engine.
The Mazda M Hybrid is our new electrification technology that regenerates and stores deceleration energy with an Integrated Starter Generator (ISG) and a lithium ion battery, reuse it as electricity to power all 12V electrical components in the vehicle, assist engine acceleration and idling stop functions to enhance fuel economy and driving performance.
