The rotary is actually a "four-stroke" engine. Each rotor face experiences distinct intake, compression, ignition, and exhaust phases. I always wonder why people think of the rotary as a two-stroke design. Only thing I can think of is the oil injection, and the lack of a valve train.

 

I would just have to say it's the nature of the beast :smirk:

 

Mine back fires also nothing wrong with it. Even when it is warmedup you might still hear one backfire every now and then but like the above persons have stated it is normal and the rotary engine is 4 stroke not 2.

 

I know its normal.My 12a and 13bs did it all the time.And with no cats you get a cannon blast when its warmed up nicely and you shut it off.A 3 foot flame when you turn the car off makes people jump high.

 

ah yes ,the flames,ive seen a friends fd do that once, it was the most amazing thing ive ever seen, i was behind the car when it happened, i think i lost some leg hair to it though

 

I really wish you would do more research before your posts.

rotary, 4 'stroke', intake, compression, combustion/power, exhaust. 4. count them.



not 2 cycles doing things in parallel per 'combustion chamber', like a 2 stroke:



the crankcase is not pressurised in a rotary engine during the exhaust 'stroke' then turned into a vacuum to draw in air/fuel for the next pressurization. They are quite different, though similar in concept (2 strokes are relatively valve-less other than the reed valve, which not all have anyways)





the rotary engine is not a 2 stroke, write it on the chalkboard 100 times.

 

i wish i had a good scanner, i could post pages out of the little silver book....

damn you guys are harsh...he was probably trying to say that it was like a two stroke

 

I just don't like my Mazda rotary jewel being compared to a weed-whacker or a chain saw.

 

im sorry for trying to ******* think..thanks for making me look like an *******



all you needed to say was...



Apex i believe you are wrong a rotary has...blah blah blah
