Engine Suggestions

I'm afraid you're going to look at my suggestions and go "Absolutely not, what are you on about? Do you have any idea how much more work that is for little or no gain?", but there is something I would really like to see in a game like this.
Essentially, I want to see the ability to make more novel engines. The one that would be my top choice is wankel-type rotary engines. I'm a huge fan of rotary engines, and I would love to be able to experiment with cars with rotary engines in a game like this one. Also, though, it would be interesting to have the option of using Miller cycle engines. Or perhaps, even things like turbine engines.
Really, though, I'd be happy with rotary engines, which, while additional work for you guys, should be immensely less work than the engines you've already implemented (a 2 rotor engine has 3 moving parts; 2 rotors and an eccentric shaft, and the other parts are the 2 housings, and the various seals and springs to hold the seals in place; adding more rotors doesn't add that much more complexity). It means adding some more technologies to research, but again, this would be relatively easy.
Regardless, I'm very interested in how this game turns out.
