Abstract
<p>Mazda announced its long-term vision for technology development "Sustainable Zoom-Zoom 2030" and launched a new initiative in helping solve a variety of issues facing the earth, society and people through driving pleasure. Under the vision, Mazda aims to reduce corporate average "well-to-wheel" carbon dioxide emissions to 50 percent of 2010 levels by 2030, and achieve a 90-percent reduction by 2050. To fulfill the vision, Mazda has developed a next generation engine "SKYACTIV-X", the world's first commercial gasoline engine to employ compression ignition. This engine, which was developed in the second step of Mazda's quest for the ideal internal combustion engine which started with SKYACTIV-G, has further increased compression ratio, improved specific heat ratio by means of lean burn, and realized spark controlled compression ignition (SPCCI). As a result, the SKYACTIV-X engine has increased the torque up to 10% overall and reduced fuel consumption over the current SKYACTIV-G, achieving the world's high-level fuel economy rate as the gasoline engine. This article introduces the engine's hardware aspects and others.</p>
