The new engines employ a system that improves fuel economy and reduces emissions.
Homogeneous Charge Compression Ignition
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.
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
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
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.
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. The article goes through al
