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:

Junkyard Gem: 2004 Mazda RX-8

You know when a type of vehicle has reached its value tipping point (where it's not worth fixing up a broken or crashed one) when examples of it begin showing up in the big American self-service wrecking yards. During 2016, the BMW Z3 and Mazda RX-8 reached that point and began to appear, just one at a time, here and there, but obviously they were the advance scouts for many to follow. Such cars usually get picked over in a hurry ... at first. Here's a well-stripped example of a first-year RX-8 I found earlier this year in a Denver yard. Some RX-7 owner probably nabbed the Renesis engine right away, and then the guys who grab late-model parts to flog on eBay were next. Still, plenty of interesting components remained on this car when I photographed it, and RX-8s that end up here in a year or two won't get swarmed by the vultures anywhere near as quickly. Does that mean that RX-8s are now cheap enough to race in the 24 Hours of LeMons? Could be!
