Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

The automaker is confident there is still life left in internal combustion.

The new engines employ a system that improves fuel economy and reduces emissions.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.

Delphi to discuss next-generation direct injection at SIA Congress

At the SIA (French Automotive Engineers Society) Congress in Rouen, France this week, Delphi will be presenting information on its latest-generation direct fuel injection and control systems for diesel engines. Delphi produces both electromagnetic servo injectors and the more advanced piezo-electric injectors. For the latest editions of both systems, Delphi has bumped the maximum operating pressures from the 2,000 BAR level that has been used in the last few years up to 2,400 BAR (34,800 psi). T

GM's FYI Blog introduces HCCI technology

If you happen to listen to the AutoblogGreen podcast, you already know how we feel about the potential of HCCI engine technology. If you don't listen to our podcast, (first of all, why not?) you can learn about the new engine type in our entire category dedicated to HCCI. Being that this is a new technology, not much is filed away under that HCCI tag though, so you might be wondering what all of the fuss is about. If that's the case, consider heading over to GM's FYI blog where they have a prime

HCCI update: Prototype in 2008

A couple months ago, Bruno pointed AutoblogGreen readers to a New York Times article summarizing the current status of Homogeneous Charge Compression Ignition (HCCI) engines, technology that attempts to take the best of both diesels and gasoline-fueled internal combustion engines. This Engineer Online article introduces us to Dr. Zhijun Peng, a professor in the engineering department at Sussex University, who is also working on bringing HCCI to the real world.

What will the car of the future look like?

If you're a fan of green car technology, then you might wonder how to explain all the possibilities (hybrids, biofuels, electric vehicles, plug-in hybrids, diesel engines, etc.) to someone who doesn't know from cellulose-based ethanol. If you've got a friend you'd like to bring in to the green car conversation, a write-up over at Political Cortex might save you time in explaining the general situation with green cars and what the possibilities are for the near future.
