Spark Less Gas Engines? Mazda Designs Diesel Like Gas Motor

Mazda, the eponymous makers of the Wankel rotary engine are now introducing a spark less gas engine.

What Is It?

The technology is known as Homogeneous Charge Combustion Ignition (HCCI,). If implemented it could deliver a 30 percent improvement in fuel economy, according to Nikkei. The technology also delivers better emissions performance. No word on power performance increases.

Several automakers and engineering houses have been working on HCCI in recent years.  Overcoming issues with cold starting and the precise timing of the combustion have made it a difficult technology to perfect. Inherently less combustible than diesel using compression to fire the fuel is more difficu8lt to deal with. Efforts have included using a part time spark plug that operates in certain temperature ranges and under specific engine loads. Mazda has not revealed exactly how its version works.

Purported to debut in a an all new Mazda 3 by initial reports, a Mazda engineer recently implied that the company was working on an HCCI version of a rotary engine. Spark less rotary powered Miata! Yes Please.
