Teaser Vid Heralds a New Mazda 3 and a New Way to Burn Gasoline

Whatever the 2019 model’s looks, the most radical change will lie under the hood. The new 3 serves as the first application of Mazda’s Spark Controlled Combustion Ignition (SPCCI) engine — a high-compression 2.0-liter four-cylinder that blends characteristics of both gasoline spark ignition and diesel compression ignition for greater efficiency and power.
To overcome inherent problems with gasoline compression ignition (temperature-related pre-ignition or lack of any ignition), Mazda kept a source of spark in the combustion chamber. It calls the new mill the Skyactiv-X.
Located in close proximity to the injector, the spark plug ignites only a small burst of fuel injected near the end of the compression stroke, right as the piston reaches the top of its travel. The resulting burn from this small, localized charge increases pressure in the cylinder, resulting in the combustion ignition of a pre-existing fuel-air mix that wasn’t concentrated enough to ignite on its own. This leads to a more diesel-like power signature and greater fuel efficiency.
Despite having a plan for electrification, Mazda remains of the few automakers without a hybrid or electric vehicle in its lineup. The investment in SPCCI was seen as a way of lengthening the gasoline engine’s lifespan while also making nice with the EPA. Assuming Mazda worked out all the bugs, the new tech stands to create a cheaper and less complex high-MPG vehicle.
