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

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:

Mazda recalling 190,000 CX-7s due to rusty ball joints

UPDATE: This post has been updated with additional information from Mazda. The Basics: Mazda is recalling 190,102 Mazda CX-7 crossovers built between February 14, 2006, to May 9, 2012 – model years 2007 through 2012. The Problem: Water can sneak in between the suspension ball joint fittings. If snow and road salt are common in your neck of the woods, the joints can corrode and separate from the lower control arms. That's bad if you enjoy steering your CX-7. According to Mazda, owners of affected models may notice a rattle from the front suspension due to the loose ball joint in the lower control arm fitting. Mazda describes separation of the ball joint and control arm as a "worst case" scenario "after extended operation in such condition." Injuries/Deaths: It's unknown if the rusting issue has led to any crashes, injuries, or deaths. Autoblog has a call into Mazda for additional details and will update this post with any new information. There have been no reports of accidents, injuries, or fatalities related to this recall. The Fix: Owners should report to their local Mazda service center, where techs will replace the both front lower control arms. Any work done is free of charge. If you own one: Mazda will perform some automotive triage with this recall, focusing on CX-7s that have had the longest exposure to salt and are most likely to suffer control arm separation first. Owners of 2007s and 2008s come first, followed by 2009 through 2011 models. Mazda will also focus on vehicles registered in states where snow and road salt are most common – Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin, and Washington, D.C. If you live in a more temperate region or own a 2012 CX-7, Mazda will perform recall work as "parts are available." Owners can contact Mazda customer service at 1-800-222-5500 for additional info. Recall notices should hit the mail around October 10th.
