Mazda compression engine to increase fuel efficiency by 30%
Mazda will launch a homogenous charge compression engine (HCCI) in 2018, aiming for fuel economy of up to 30 km per litre, a 30% improvement on conventional gasoline engines. Automakers have experimented with HCCI engines since Mercedes demonstrated the technology in 2007 but it has not made its way into production vehicles until now. Infiniti also plans to launch an HCCI engine. Mazda considers its future to lie with internal-combustion engine vehicles but will release an electric car in 2019. The HCCI engines will first be deployed in the Mazda3 compact model.
TOKYO -- Japanese automaker Mazda Motor will introduce a new engine at the end of 2018 that offers 30% better fuel efficiency by using pressure, not spark plugs, to ignite fuel.

This will be the first practical application of the technology, called homogeneous charge compression ignition. Though the automaker is developing environmentally friendly electric vehicles, Mazda thinks the internal combustion engine will continue to account for the majority of new-vehicle sales for the foreseeable future and that the company's technology will give it a leg up on the competition.
