Wenkel Engines: Untapped Potential?

06/25/2008 11:06 PM

26.6.08

A quarter of a century back, there was much talk of this approach to building engines. If my memory serves me right, Mazda was the only company commercialising this technology in a major way. The underlying concept was elimination of the crankshaft and the commonplace reciprocating engine. With high fuel prices, is it time to revisit this technology? Why did this promising concept never take off? Is it a case of commercial inertia? Intrinsically what promise does it hold for fuel efficiency vis a vis the conventional IC engines?

The promise it holds is that it will require more fuel for the same task - Imagine what it can do to you.

The Wenkel must be the electronic injection version of the Wankel!

Ingersol Rand tried an industrial version of the Wankel. It failed because of mechanical issues and fuel economy was low.

As already pointed out by others, it's 'Wankel', as in Felix
http://en.wikipedia.org/wiki/Wankel_engine

Until Mistral came along, they were just too thirsty..

Is this the same WANKEL rotary engine that the Mazda R-7 engine uses? I've never heard of a Wenkel engine?

Mazda was not the only Mfg. working to develop and manufacture working rotary engines. Sachs Motor Co. also Mfg. rotaries and used them in chainsaws, snowmobiles and motorcycles. I have read of outboard motor development that also didn't go far or last long. The problems included poor fuel economy and problems with seals. Mazda sorted out most of the problems and won their class at Le Mons in France. One of the things I find interesting is the assorted fuels that might be used to power this configuration.

Oops! Sorry for the spelling bloomer. Just goes to show how rusty the memory on this has become. In reciprocating engines, there is fore and aft, and one of them is non productive. In rotaries, everything is progressing ion the right direction. From a layman's perspective, this holds promise for higher efficiency. Technologies similar to MPFI, CRDI etc used to extract more juice from Conventional engines possibly have not been extended to these types of engines. Methinks this technology has still not got its due.
