Rest In Peace, old friend, your work is finished.......

If you want on or off the DIESEL "KnOcK" LIST just FReepmail me........

This is a fairly HIGH VOLUME ping list on some days......

New Engine Ping!......

“Bortone cycle” ? I am a little skeptical of new cycles being discovered this late into the game. But then , who am I ?

[P-40]

The Italian company has been developing the prototype with €2.5 million (US$3.3 million) in government grant money.

If it was any good the private sector would have already done it. :) /sarc

It’s all for nothing if it doesn’t meet air quality standards. Many 2-cylinder engines don’t meet spec in that area. Just look at all the small-displacement engines that have gone 4-stroke in recent years.

IMO, we need to decide which is more important.

[Incorrigible]

I thought two stroke engines had higher exhaust emissions?

[Abathar]

You can always tell the machinist took the picture when they use a couple of V blocks to hold the engine up strait on the bench as opposed to the engineers who would use books.....

It’s got to be good, it’s a NEVIS!

Didn’t see a PV curve of the Bortone cycle.

Jet-Engine Inspiration
Another potential player in the race to 100 mpg is the StarRotor, which began life as an air conditioner at Texas A&M University. Chemical-engineering professor Mark Holtzapple and his colleague Andrew Rabroker were attempting to build a better compressor for an air conditioner when they hit on the idea that became the StarRotor engine’s basic architecture. Once they made the connection to car engines, “we quickly forgot about air conditioners,” Rabroker says. They have since formed a business (also called StarRotor) to commercialize the technology.
The StarRotor uses the same thermodynamic process as jet engines to recuperate some of the heat normally lost to exhaust, something that the design of a piston engine doesn’t allow. The exhaust heat warms the air that comes into the engine before the fuel is added [see illustration, below]. This hot air leads to more powerful combustion, which means the StarRotor can extract more energy from a given amount of fuel than a conventional engine could.

Reminiscent of the Wankel. Do you think the seals on this citter will hold up any better?
