Hi, over the years i have had the chance to learn a lot over these boards. One subject that i feel has been an area which mosyt people know little about is this. Unfortunately i am one of those people i know little or nothing about them.

Can someone explain them please, how do they work?
I remember someone saying something like a 1.3 rotary would be the equivellant of a 2.6. Why?

Any info would be appreciated.

Thank you in advance.

Sev - Here's a good link on how a rotary engine works: http://www.rx7club.com/resources/articles/wankel.html
Enjoy.

Sev, I think you get a power pulse every revolution (2-Stroke Style).

Hey Sev...
Had many Mazda's over the years here. First was an '81 Mazda 626, my college car. In '84 I bought an RX-7. In '87 I picked up a TurboII. I was then priced out of the Mazda line as I could not afford the Twin Turbo (Lucky for Honda). Quite simply the piston engine losses a lot of energy in that the pistons go up and down, thus reversing direction, and losing inertia (i.e. energy). The beauty of the rotary is that it does not lose any inertia. It goes one way. Don't know if the 1.3 vs. 2.6 is accurate, never heard any hard numbers.

While I can't add much in terms of technical specs, I can say that FINALLY, Mazda has come to its senses and realised that the rotary engine is an important part of its heritage, and subsequently has provided the necessary funding to develop the next generation Wankel. Expect to see it in the RX-8, a screamer similar to the S2000, with about 160lb/ft of torque, 250hp and a redline of about 10,000rpm.

I really enjoyed reading that article--thanks for posting the link.

I do have a question though, anyone know how oil is dealt with in this situation? How is the "rotor" lubricated?

Thanks in advance.

I know what you mean, I wish I understood them a little better. Great emgines they say

Oil is injected almost like you would fuel. The motors are basically 2-stroke. they consume about a quart of oil per 1000 miles (approx). the weird thing is - if you blow an apex seal (which is analogous to a piston ring) you don't get smoke at start up because there isn't an oil sump on the other side. This actually just happened to my friend's RX-7 on wednesday night at the dyno. No smoke, but it's blown.
