If you've read our recent article about a report for the upcoming Mazda3, you'll be familiar with this one. Mazda has officially announced the next-generation SkyActiv-X engine that will leave the automotive world with dropped jaws – a gasoline engine in nature that processes like a diesel powertrain.

As we all know, gasoline-powered engines require spark plugs to start. This small component is the one responsible for ignition, which is a big deal when it comes to combustion engines. Take this away and the car won't start – something Mazda wants to change.

The Japanese automaker has expressed its plans on a spark plug-less engine earlier this year with the help of the homogenous charge compression ignition (HCCI). This is in part of the Mazda's "Sustainable Zoom-Zoom 2030" vision, which aims to provide solutions for a greener earth.

Basically, the SkyActiv-X engine burns fuel by compressing the gasoline and air in the combustion chamber – just like how a diesel engine works. Mazda calls this method as Spark Controlled Compression Ignition, which combines the advantages of gasoline and diesel engines for better power and acceleration at a cost of low emission.

Currently, Mazda's SkyActiv-X gasoline engine is under its developmental stage. It is expected to come out in 2019 as the first gasoline engine to use compression ignition.
