Mazda has announced its new line-up of gasoline engines using direct injection, which comes after Ford's announcement of its Ecoboost range of engines. The name Mazda chose for this technology is DISI, which stands for Direct Injection Spark Ignition.

First of all, Mazda has a new I-4 DISI 2-liter gasoline engine. DISI includes a whole new set of innovations for gasoline engines. To mention a few, direct injection (including cooling the air-gasoline mixture), a new combustion chamber geometry, variable timing technology, and nanotechnology for the catalyst. This all makes the engines consume 20 percent less while getting 15 to 20 percent better performance.

Mazda has announced further developments for its diesels: new direct injection technology (most European automakers are switching to piezoelectric injectors), making the engine lighter, DPF, and urea technology to reduce NOx emissions

And, last but not least, Mazda spoke about its latest iteration of Renesis, the famous rotary engine: increasing the size, improving the shape of the rotor, and using direct injection and aluminum side housing.
