DIESEL KNOCK!...........................

[RoosterRedux]

I wonder who China stole this idea from?

Chinese people are very bright but the history of collectivism in China has a tendency to remove the incentive for individual inventiveness.

How many mpg say in a volvo does his equate to?

[Paladin2]

Can I apply these innovations to my brace of ‘05 VW TDIs?

[Nateman]

.

This is the ultimate efficiency possible for a heat engine. Temperatures are degrees above absolute zero.

I’m holding onto my diesel longer than I otherwise would because I can’t get a new one.

Fourteen percent better mileage for me would mean 52mpg on the Interstate.

[Red Badger]

On a personal basis that may not seem like much, but suppose you had a fleet of semi-tractor trailers that travel across country, thousands of miles each day. That would be a fuel savings in hundreds of thousands of dollars....................

"2024 World Congress on Internal Combustion Engines" in Tianjin, China

Were any American companies there? Or are they all too cowed by Brandon and have totally repudiated ICE?

"The engine’s economy improves with the base engine’s increased thermal efficiency."

That's like saying "the efficiency goes up as the efficiency goes up."

---

"A heavy-duty tractor with a yearly mileage of 155,342 can save 12,000 gallons of diesel fuel...which results in an annual savings of almost $13,529."

Coincidentally, Brandon announced a new tax on diesel long-haul trucks of $13,529 per year. Purely coincidence, I'm sure.

Where does this goofy theory come from that scientific innovation and technical progress depends on the political Regime ?

Euler did some of his most important work while in Tsarist Russia.

Mazda’s diesel.

Study the history of collectivism in China. It's ancient. And it was a cultural/societal characteristic millenia before Mao.

Most Americans know that individualism and capitalism encourage inventiveness. Milton Friedman can explain it to you.

[RoosterRedux]

Tsarist Russian wasn’t collectivist, was it?

[US_MilitaryRules]

What was it when the diesel engine was invented? 20%?

"How many mpg say in a volvo does this equate to? "

-----------------------------------------

The problem with all these engines and a focus on peak efficiency is that most of the time passenger cars and even heavy trucks operate at low rpms and part throttle which is much less efficient.

Gas turbines, for example, are much more efficient at peak power than gasoline engines. But gas turbines are horrible gas guzzlers at part throttle and low rpm.

This is a typical diesel map from older less efficient diesel era. Gasoline would be similar with lower efficiency everywhere

I know you always find these articles and I too think diesel is the way to go.

[Reverend Wright]

In the 19th century, students at US Universities studying sciences had to learn German.

They needed to do that because Germans were the leading scientists of that time and the scientific literature was in German.

According to you, that couldn’t have happened because German scientists under the KaiserReich couldn’t possibly compete with American freedumbs.

[RoosterRedux]

You're nuts...or perhaps just confused.

My comment--now listen carefully--was that collectivist cultures have a negative effect on inventiveness.

You might want to take a look at your own tagline.
