opposed (free) piston engine(s)

[D'ARTOIS]

Yeah, I had a look. Some of those bojo's are ex-clients of mine. very funny.

[yipster]

any thoughts on something like this?

www.dynacm.com is no more?

Did they go under?

[yipster]

what a pitty, i still liked it but cant find dynacam back eighter, only this reference
small airplane engines were used in patrol boats and some unusual designs i cant help admiring.
above i was back with an under water augmented pulsejet, can think of some chances and was wondering what it would do.
i favor the idea of a free piston or pulse engine and even a sliding bear cam may today do its time in a boat.
guess only big multinational conglomerates that control politics survive these days wich nasa never was or isnt anymore?

One of the entries in Ypisters link is pretty funny.

I don't post often and have never entered one of these threads before, but
when it comes to the respect that Indy gives to the development of better
automotive technologies I have to interject. In 1967 Parnelli Jones nearly
won the Indy 500 with a four wheel drive gas turbine powered car. It was
faster and got better fuel economy than the piston engines. If my memory
serves me right it was a transmission problem in the last lap that made him
drop from first place. To most people this would seem like a huge step
forward in racing technology, but instead of allowing this technology to
develop on the track and quickly reach consumers Indy decided that they
would limit the size of the air intake so that a gas turbine powered car
would not be able to race there. Ask yourself if it makes sense to limit
the one thing that people don't care if there car uses too much of (air).
So as for your question about why they use V8s in Indy cars/ U.S. sports
cars, it's because of ignorant, close-minded *******s like you. Thanks to
people like you, we aren't all driving really ******* fast, SUPER high
efficient, gas turbine cars.

I thought Indy rule makers flat out banned the turbines and AWD/4WD at the same time.

I just ran across this old subject as well...too bad it has apparently disappeared. Here is some other reference discussions and photos for review.

Thanks for that link....pretty nice slick presentation on that website...

....but look what just turned up

Thanks Wscott52. I just found and read this rather long discussion that seems to lend credence to your warning.

So even if the technology is good, it appears to not be in the hands of a viable developer.

I always wonder about these magic engines and the web sites never show a bunch of them working anywhere
