2019 Mazda3 to Feature Sparkless Gas Engine

2018 Mazda3

The future of powertrains is upon us. In fact, there’s a future Mazda to sport an innovative sparkless gas engine – the 2019 Mazda3. This model, slated for release in 2018, will feature the first-ever Homogeneous Charge Compression Ignition (HCCI) technology, which has been in development for decades, but has yet to make its debut. Find out more about the first Mazda to sport this innovative sparkless gas engine.

What is HCCI?

Mazda is no stranger to developing innovative engines, as evidenced by its SKYACTIV™® technology, so its new HCCI technology should come as no surprise. HCCI engines function similarly to diesel engines. Engines with this new technology ignite without a spark thanks to compression, yet they run only on gasoline. Typically, gas engines rely on an ignition that sends electricity to spark plugs, which ignite fuel inside a combustion chamber. Efficiency is greatly enhanced and emissions reduced with HCCI engines, as a homogeneous mix of air and fuel burn at lower temperatures.

In turn, this lessens the heat energy lost in typical gasoline engines. However, due to specific temperature needs for this technology to function properly, Mazda’s engine is said to incorporate sparkplug ignition capability, to be used as necessary when temperatures are too cold for the HCCI engine to start on its own. Mazda’s HCCI engine comes as part of the automaker’s next generation of SKYACTIV™ technology.

Debut

Details about Mazda’s HCCI technology will be revealed in the coming month at the Frankfurt Motor Show. Rumor has it that Mazda will then introduce a concept of the redesigned Mazda3 in October at the 2017 Tokyo Auto Show. The new system will first hit the market in Australia, and drivers in the United States will likely have to wait until 2019 to access it, if Mazda decides to offer HHCI in the U.S. at all. The Mazda3 is currently the only car scheduled for HCCI engine use.
