Japanese carmaker Mazda has developed a extra environment friendly petrol engine at a time when the business steers towards electrical autos.
It mentioned the compression ignition engine was as much as 30% extra fuel-efficient than its present engines.
It plans to promote automobiles with the brand new engine from 2019.
Final week, Mazda mentioned it will work with Toyota to develop electrical automobile know-how and build a $1.6bn plant within the US.
Mazda analysis and growth head Kiyoshi Fujiwara mentioned it was crucial for the corporate to pursue the “supreme inside combustion engine”.
“Electrification is important however… the interior combustion engine ought to come first,” he mentioned.
Mazda mentioned the Skyactiv-X, as it’s identified, could be the world’s first industrial petrol engine to make use of compression ignition.
The know-how breakthrough places the agency forward of rivals together with Daimler and Basic Motors which have labored on compression ignition for many years.
In response to Mazda, the fuel-air combination ignites spontaneously when compressed by the piston within the new engine.
The carmaker mentioned the Skyactiv-X mixed some great benefits of petrol and diesel engines to enhance effectivity.
It has no plans to produce the engine to different carmakers.
The transfer comes because the automotive business pours large funding into electrical know-how in response to stricter emissions requirements around the globe.
The UK will ban the sale of latest petrol and diesel automobiles by 2040 in a bid to scale back air air pollution.
In July, Volvo said all new models will have an electric motor from 2019. The Chinese language-owned agency goals to promote a million electrical automobiles by 2025.
Mazda additionally plans to introduce electrical know-how in its automobiles from 2019.

In principle, a compression-ignition petrol engine ought to have massive benefits. However it is not simple to make know-how work – and among the largest corporations, together with Basic Motors, have already tried.
So why ought to a comparatively small Japanese producer like Mazda succeed? Effectively, partly as a result of – in contrast to the actually massive gamers – it is not afraid to take dangers. It has accomplished previously.
It is the one mainstream producer, for instance, which has endured with rotary engines in its automobiles. Like compression ignition motors, they’ve theoretical advantages, however create complicated engineering challenges.
Mazda’s rotary has had some success. The corporate gained the Le Mans 24 Hours race with it in 1991, and the most recent model was fitted in its RX-Eight sportscar. Well-liked with drivers, it was sadly unreliable.
If the brand new motor is to be a hit, it must be dependable in addition to environment friendly. And Mazda wants to have the ability to persuade regulators that petrol engines nonetheless have a robust future.
It might show to be the proper stop-gap, as electrical automobiles are developed and charging infrastructure is created.
Or it might develop into a superb thought, which has come to fruition just some years too late.
