Swash plate — https://en.m.wikipedia.org/wiki/Swashplate
Inefficient at converting linear reciprocating to rotary motion.
No valve and ports — dirty on I burned hydrocarbons.
High compression — dirty on NOx.
Going nowhere..
Yeah, that was my question, what are the emissions like.
The wear between the head and the cylinders will kill it.
How is a swash plate inefficient? If it does not produce heat, and I cannot imagine that it does, or at least not much, how is it robbing power?
Some where I have a swash plate compressed air motor I built. Converted it to steam and got about 4 amps at 12 volts out of it.
Ah, that great engineering reference, Wikipedia....
Emissions will be mitigated through electronic engine controls. That’s how the same basic IC engine that was in Andy Griffith’s squadcar now gets 30 mpg.
