Diesel Knock List!................For Gasoline!..............
What works in the lab doesn’t always work in the real world, for many reasons.
I miss my RX-7
My dad is an ASE-certified mechanic and worked on Mazdas. He talked about how those engines were complete trash. So problem-laden.
Of course it doesn’t work.
Mazda were always wanklers anyway.
I had a 1973 RX-4 never drove it much as I was in the military my younger brother hit an elk while I was on TDY and it didn’t survive..
Pretty good explanation here: https://youtu.be/lsPhQaramio?si=Fz1IloPVfOEKvVge
Mazda goes hmmmm?
Their Wankel engine went bust too...
Stratified charge engines have been around for a long time.
The Honda CVCC engine was one example.
A good idea that does not translate to real life well. SX engines are more complex to manufacture and are difficult to maintain at the dealership. At a time when efficiency combined with cost-cutting need to merge, SX engines fail the test.
Mazda does make fine autos though ...
I had a Mazda GLC in the early ‘80s when I was in college. It was the cheapest and worst put-together car I ever owned.
Maybe it doesn’t like ethanol. Americans are in luv with their ethanol. Yuck!
The Mazda HCCI engine was probably squashed by a consortium of spark plug manufacturers, led by Bosch, who saw a threat to their bread and butter. </sarcasm>
Neighbor has a Mazda with that Skyactive engine in it. Raves about the fuel economy. It’s actually a nice looking and well appointed vehicle too.
This guy got one in to tear down and see where it failed. He couldn’t really tell exactly why it failed but generally, he likes this engine.
Dude knows his stuff and has an interesting channel. He tears down blown and broke engines:

It was Wankeled.
Like the Wankel engine? “Piston engine goes ping, ping, ping, but the Mazda goes Hm-m-m-m-.”
Attn Otto.
LOOKS VERY COMPLICATED
