Hue hue hue. Here’s my rotor which was damaged by a chipped/broken apex seal.

I thought those rotor housings and plates were as small as cylinder bores. hahaha

You said something about reliability. How is it reliable?

I said *can which is true. It’s a simple design, often simple is better. Far less moving parts means less to worry about. Just because someone said Apex seals on the internet doesn’t necessarily mean the driver took great care of their car, or put too much boost, etc.. Keep it maintained, keep plenty of oil in it, and they can be reliable. But like anything, they can also be unreliable.

Hey EE,

Is it okay for me to start a channel inspired on yours?
I want to do it in dutch.
And do you have any tips for starting a informative youtube channel?

We have a rotor as a doorstop at my college

This was informative. Since lubricating the housing is so essential, I suppose there are modifications available to assist that? Or is it merely a case of making sure the oiling system is working correctly, there is enough oil in the motor, and that it’s added to the fuel mixture in the tank?

You can buy higher flow oil injectors on rotary engines, which are usually used for porting and/or forced induction. I have, however, seen people squish the oil injectors down in a vice. Can’t remember exactly how this works but it shortens a spring inside the injector and gives a higher flow this way. Keep in mind these are only really required if you perform serious mods to your car (turbos, any kind of porting) and most stock rotaries should last as long as you have correct oil levels and use the right oil.

Adding oil to the fuel is the simplest way. Just some 2-stroke oil.

Would it be possible to run oil through the eccentric shaft and to the rotors so they would get lubricated “from the inside” instead of having to inject and burn oil? Would it be possible? Has it been tried?

There’s nowhere for the oil to escape to -it has to lubricate the tips of the rotors. In a piston engine, it lubricates the cylinder wall, but the “oil control” ring at the top of the piston wipes the majority of the oil back down the cylinder so it never gets burned. On a rotary, there’s nowhere to wipe the oil to, as combuston happens on both sides of the seal - thus it gets burned.
