I had heard about HCCI engines and thought it would he difficult to ever get them to really work reliably with the current technology... Companies have been messing around with it for quite a while i think since the early 2000s. Seems like Mazda figured out how to make it work with that sort of but not really compromise.

Always a negative one. :lol: I'm not terrible impressed with this concept, because a lot of old largediesel engines were sold as
LP or natural gas engines, and as I know it, they were all spark fired, but, most of them in diesel form would run on gas vapor (fume) if
atomized through the intake air.. In fact, out here in Hickville Ky. where I graduated eight grade, a lot of us used a gasoline soaked rag
for a starting aid, and I have personally have ran a few diesel engines for short periods on gasoline.

So I think it's a bunch of hype, over rated and good for sales, not the customer. With the quest for better quality , we are getting
gadgetry that is overly technical and expensive and not DIY friendly.

After all Zoom Zoom sold us the rotary engine didn't they ? :roll: and then a diesel pu that we never knew the manufacture of, Perkins?
or Zoom Zoom ?

Zoom Zoom is not the only one, there has been oval pistons, split journal crank shafts, tire pressure censers, HEUI fuel, and air bags,
and the list goes on.

They say, this is the technology that we send people to the MOON. They refuse to understand that it works better in a nothing
environment than hear on earth with all the elements.

Toyota says they have much to learn from Mazda .....


https://www.youtube.com/watch?v=Zacs_A6TyrA

From an article* about the Mazda / Toyota partnership in 2015:

"For Toyota, the deal also gives it a front-row seat to study Mazda.

Toyota engineers say privately that their company has been quietly benchmarking the comparatively tiny Japanese rival, fascinated by its uncanny ability to churn out high-quality vehicles on a shoestring budget -- and to do so profitably from high-cost Japan.

Toyoda said that despite the difference in size between the two companies, Toyota has much to learn from its pint-sized counterpart.

“In a sense, Mazda is ahead of us in many areas,” he said.

Mazda’s high-compression Skyactiv engines, efficient transmission and lightweight chassis systems, as well as its Kodo design language, are prime examples of areas where Mazda leads Toyota by a “full lap,” Toyoda said."

Since then, an announcement that the Mazda HCCI engine will be in production soon .......

Sometimes you have to do less reading and do your own thinking, but if you are under 50 years old, you probably won't understand what I'm talking
about. Because I have seen the changes and now I can see through the smoke. So if any one wants to, do a little study on things that are hi-tech,
expensive, and doesn't work too well.. ever here of magnesium pistons? they decompose fast in use or not. Duel mass flywheel ? what's that knocking ? the list goes on and on.
If you look at it like they ALL have the same investors, things may look deferent ..darrell

I owe an apology to you guys, 85PUPDSL and Paul, my deepest regrets for hi-jacking your thread 85PUPDSL, and for being so defensive and
maybe insulting in my choice of words.. But that wasn't my intension, I simply get tired of seeing the embalance of trade of hard earned
money for inferior, high-tech, O well it didn't work, junk..

They all build more dependable stuff for the third world countries, where they don't have service departments, probably cheaper.

Next new thing is, you buy the car and the computer in it, but its against the law to work on it, because they own the software and run program..

Think, how stupid was the idea of a foil covered lug nut? Fine around the tire shop, but not so good when it fails out on the interstate, and the
wheel wrench won't fit any more.. Who does a study on how many fatalities this has caused, consequential to being on the road side too long..

thanks Darrell
