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:

Question of the Day: What's the most irritating car name?

You hear a lot about how the Chevrolet Nova was a sales flop in Mexico because "No va" means "it doesn't go" in Spanish; in fact, the Nova sold pretty well south of the border, and in any case most Spanish-speakers know that "Nova" means "new" in Latin and Portuguese. However, General Motors doesn't deserve to be let off the hook for bad car names, because the Oldsmobile Achieva— no doubt inspired by the excruciating "coffee achievers" ads of the 1980s— scrapes the biggest fingernails down the screechiest chalkboard in the US-market car-name world. That is, unless you think Daihatsu's incomprehensible choice of Charade was worse. Meanwhile, Japanese car buyers could get machines with cool names like Mazda Bongo Friendee or Honda Life Dunk. It's just not fair! So, what car name drives you the craziest? Related Video: Auto News Design/Style Chevrolet Honda Mazda Daihatsu Automotive History questions car names
