Drudge Retort: The Other Side of the News
Saturday, October 28, 2017

In the high-stakes, high-cost battle among global automakers to develop ever more efficient vehicles, one of the biggest breakthroughs in internal combustion engine technology in years looks to be coming from one of the industry's smaller players. Japan's Mazda Motor Corp has zoomed past its larger global rivals to develop an engine which ignites gasoline using combustion ignition technology, a fuel-saving process considered something of a holy grail of efficient gasoline engines.

As global emissions regulations get tougher, not only could Mazda's technology prolong the life of internal combustion engines, it could also improve "greener" engines as they can be used to produce more efficient gasoline hybrid and plug-in hybrid vehicles.

Mazda will showcase the Skyactiv-X technology at the Tokyo Motor Show this week. When it launches the engine in 2019, the automaker says it will deliver as much as 30 percent fuel efficiency over its Skyactiv-G engine, already one of the most fuel efficient gasoline engines on the market.

"Our resources are limited, so unlike bigger automakers, we don't have the array of options in which to invest our R&D funds," said Mitsuo Hitomi, managing executive officer at Mazda who oversees engine development. "That's why we're betting on this technology ... We were determined that no matter what, we would develop this engine," Hitomi told Reuters in an interview at the company's headquarters in Hiroshima.

Great, they've invented a diesel engine that runs on gasoline.

I think I'll go work on my new telegraph system.

With such precise timing involved I wonder about the longevity of this motor and how often it'll need to be re-timed to stay running.

Rolling coal, yabba-dabba-doo style.

Little-known fact: The name "Mazda" comes from the Persian Zoroastrian god "Ahura-Mazda," which predates even Judaism.

The name means "Mighty Wisdom" in Avestan/Old Persian and is represented by this symbol: upload.wikimedia.org

Damn it. Coming from Mazda, despite all evidence to the contrary, I hoped they'd figured out how to resurrect my long-gone but much loved rotary, only maybe without the horrible gas (and oil - let's not go there) mileage.

I miss my RX7. Stupid, completely impractical, fun as hell little gocart.

Since there is a finite supply of dinosaur-squeezings, cars powered by them are on the way out. That especially includes the automobile as an article of amusement. If petroleum only fueled cars, and had no other uses, it wouldn't be such a big problem. But cars are by far, the largest users of oil, and they are the most inefficient.

The additional need to feel g-forces increases that inefficiency to astronomical levels.

Despite what car commercials tell you, it is a part of our culture that will be completely gone in 50 years.

#1, detail designs aren't revealed in the article but the development applies to diesel and gasoline engines. They appear to be increasing compression, a well known way to increase efficiency, limited largely by material science. The other seems to be varying the timing with engine speed, another well known, but mechanically complicated problem. For the gasoline engine they also hint at a new spark plug.

Materials able to withstand higher temperatures and pressures in a compression engine has always been a limiting factor.

that will be completely gone in 50 years.

I think even sooner. 20 somethings already don't give a crap, they see a car as a way to get where they are going, they don't care about 0-60 or high top speeds they care about getting there an operations cost. Give them a car that they can run for 200k miles for a total cost of ownership of 10 cents a mile and it will sell like hot cakes even if it's top speed is 80 and it takes 30 seconds to hit 60. Oh but not a ---- smart car it needs to hold 4 people min. since their friends all ride in one car.

You can give millennials a lot of grief but they are going to change the car industry a lot faster than most people expect. In far less than 50 years, I would guess 20. In 20 most boomers won't be driving, most x'ers will be retired and driving a lot less and the major car purchasers will be millennials.

"20 somethings already don't give a crap, they see a car as a way to get where they are going, they don't care about 0-60 or high top speeds they care about getting there an operations cost."

The car is no longer a crucial part of the teenage mating ritual in America.
Like any change in the culture, that scares conservatives.

#9 - I don't disagree with you but in 20 years we will see a paradigm shift more because of driverless vehicles than millennials influence.
