Answer me this if anyone can give a correct answer cuz im a little foggy on this part of the rotary engine.

Given the nature of the rotors themselves and how the spark plugs are oriented inside the rotor housing, when the edge of the rotor passes over the spark plugs for a split second there is a open gap that would allow the expanding gas into the forward and aft rotor chambers correct? I guess that the rotor passes it so quickly that it doesnt really matter but still am I correct in thinking? Although the blowby into the next chambers wouldnt effect power that much wouldnt it cause pre-ignition in the following chamber?!?

If I am thinking right with the way the rotation goes the chamber that is on the compression stroke could only leak into the chamber that is currently in the ignition phase. The pressure from the ignition part would most likely be higher than the compression chamber and only add to the compression. By the time the apex seal got to the spark plug hole it would be so close to the time for the spark to hit, it probably wouldn't make a difference. Plus the hole on the inside of the rotor housing for the trailing plug is very small. Or I could be all wrong, but it is an interesting thought.

forward and aft chambers? The intermediate housing keeps the front and rear rotor chambers completely separated. Unless you're talking about some really freaky leak through the e-shaft

i see what ur saying....pretty interesting...i guess it's been positioned in such a way that the gas that just got ignited is being blown out and their might be very very minute amount of gas creeping into that chamber but then again it is going soo fast i don't think it would matter too much

peejay

Now you know why the trailing plug hole is so small.

If you have an engine part, look for chatter marks on the top part of the rotor housing. Then put the rotor in there with one of the apex seals over where the chatter marks start... then look where the other apex seals are ai.
