Engine Breaking in a rotary
Engine Breaking in a rotary
I've seen a few threads on here about weather or not engine breaking is safe to do in a rotary engine, I'm looking at getting into rotary engines and just want to know if this is something I should stop doing in my current car in prep for driving a rotary or if its something that is fine to do.
by engine braking, u mean shifting down the gears coming up to a stop, i've been doing it for yrs. never been a problem. breaking the engine is very bad, tho.

This isn't a 2 stroke where engine braking will starve the bearings of oil. (Why SAAB had a one way clutch on the transmissions designed for their 2 stroke engines... which even carried through to their Ford V4 engined models)
The only time you do run into a potential issue is if you remove the MOP and do a lot of high RPM deceleration, which is where road racers who premix will generally just turn the idle speed up to 2500rpm or so so that there is always a good amount of air and fuel (and therefore oil) flowing through the combustion chambers with the throttle closed.
All that said, there isn't very much engine braking, which is kind of one of the huge benefits. When the tires spin, and you let off, the low amount of braking and the low engine inertia means the tires have a chance to get traction again.

engines inevitably break on their own. we haven't figured out 100% reliability yet. if you have a habit of doing it then yea, you may want to stop. rotaries are expensive to replace
