Look, the engine does 2 power outputs every cycle of the crank shaft. a normal 4-stroke engine does 1 power output every 4 cycles of the crank shaft, thus the rx7 which is 1.3 litre engine produces the power more like that of a 2.6 litre engine.
The big disadvantage of this engine (dissregarding fuel economy) is that it is very vulnerable and engineers give it a 60 thousand mile life span ONLY. I used to own one and it broke down alot...
take a vulnerable engine and add turbos, what do you expect. rx8 is said to be much better, relyability wise
I hear at the end of 2004 we will se the 4th generation RX7, so the RX8 may not be a replacement
my good buddy is a certified Mazda mechanic and he tells me that the rotary engines are "just replaced" with factory parts
They dont really let/like people getting into the engines.
So because it is expensive people just drive till they blow.
I dont tnink they are in actuality to much trouble.
I used to have a transparent rotary engine.
It ran on electricity; but the mechanism was rather complicated.
I saw some that you guys probably mentioned; never drove one, but nice concept ! Is it really quiet and devoid of all undesired vibration ?
I may stand corrected - but I think that there has always been a problem with oil seals in Wankel engines....particularly the seal at the end of the rotor. This has always seemed to be a particularly 'tough nut to crack'.
Other than that ...... they're great !
(Engine braking, of course...seems to give a little problem to new drivers, too....!)
