Mazda Bringing Out First Commercial Fuel Efficient Compression Ignition

Mazda will be the first-ever automaker to commercialize a gasoline engine with compression ignition, making it 20 to 30 percent more fuel efficient than Mazda cars equipped with the Skyactiv system.

Mazda Motor Corp. yesterday released its Sustainable Zoom-Zoom 2030, which outlines phase two of a corporate campaign supporting a sustainable planet. It includes a “well-to-wheel” strategy for corporate carbon dioxide reduction, efficient vehicle technologies, and a commitment to roll out electric vehicles.

The next-generation engine, called Skyactiv-X, will be released in 2019. It’s compression ignition will make sure the fuel-air mixture ignites spontaneously when compressed by the piston.

The company said it has a proprietary system called Spark Controlled Compression Ignition that takes care of two stumbling blocks that have kept other automakers from being able to commercialize the technology. The first is maximizing the space where the compression engine functions; and the second achievement is finding a seamless transition between compression ignition and spark ignition.

Skyactiv-X will utilize the new compression ignition plus a supercharger fitted to improve fuel economy. It will gain 10 to 30 percent more torque than the current Skyactiv-G gasoline engine, and 20 to 30 percent better fuel efficiency. Compared to 10 years ago, it will have 35 to 45 percent more fuel economy over the 2008 Mazda engine with the same displacement.

It will be equal to, or exceed, the latest Skyactiv-D diesel engine in fuel efficiency.

Mazda attributes the fuel efficiency and performance of its Skyactiv technology as being behind increasing sales of models like the Mazda 3, as seen in the photo above.

Another benchmark set for 2019 will be launching the first Mazda electric vehicle and “other electric drive technologies in regions that use a high ratio of clean energy for power generation or restrict certain vehicles to reduce air pollution,” the company said,

That’s likely referring to compliance with strict emissions reduction targets in markets like China, Germany, and other European Union member nations. It also ties into Mazda announcing days ago that it will be developing EVs with Toyota Motor Corp.

It also implies the company will take a broad approach to electrification. The Toyota agreement will focus on battery electric vehicles, and Mazda’s “other electric drive technologies” may include plug-in hybrids and hybrid vehicles.

Sustainable Zoom-Zoom 2030 will go the same route other companies like Toyota and Honda are pursuing using the well-to-wheel concept aimed and reducing fossil fuel consumption in the vehicles, but also adopting cleaner practices in building and maintaining the cars over their lifetime. It also supports using clean energy to manufacture vehicles and to charge up Mazda electric vehicles.

Mazda wants to reduce corporate carbon dioxide emissions by 50 percent compared to 2010 levels by 2030, and by 90 percent in 2050.

Mazda also committed to making its vehicles safer and more automated. The Mazda Proactive Safety philosophy will move toward the goal of eliminating traffic collisions in its vehicles.

Enhancing connected car features, like i-Activsense that helps drivers recognize and avoid potential safety hazards, will be part of the mix.

On the autonomous vehicle side, testing will begin soon on automated driving technologies that will come in line with Mazda Co-Pilot Concept2 in 2020. The company described the concept as being “human-centered,” implying that it will be based on Level 3 or Level 4 standards on autonomous vehicles, allowing the driver to take over.
