General rotary question
Not sure when I thought of this, but how exactly does the rotary engine keep it's compression when the apex seals move over the spark plug gaps?
|
same as a pist on engine does, the plug acts as a plug in the hole.
|
but the plugs are not completely flush with the rotor housing.
|
So you loose what, about 3cc of volume if not less? It's not that big of a hole thus it's not a concern where compression is concerned.
|
but if the apex seal stops (or just goes slow) in the middle of this gap, it will lose all it's compression to the other side of the seal. I'm assuming this is less of an issue with higher RPMs then?
|
You should think that thru again
|
maybe it would help me if someone posted a pic of a bare housing with a plug in it.
|
The spark plug is much wider than the apex seal so if the seal stops over the plug you can lose compression. However, the period when the seal is over the plugs is probably less than a millisecond so there is virtually no time to lose compression through a very small gap.

The seal does not simply rotate past the plugs. Its a eliptical rotation. Up and Down while going round and round. Also the volume of the spark plug holes is there during the intake cycle, so volume is not lost on the compression cycle

oops, triple post, server ain't working too well today, it gave me three errors in a row but posted the message each time.
