Heads, 3 valve

A 2-D study of a three-valve head.
Here is the 2-D CAD file:

This is a flat-lander (2-D) study of a three-valve head. The cylinder base is traced off a 1000cc iron head. This is intended to be an aluminum head.

Four valves head don't work well on air-cooled engines since there is so much exhaust port surface area. They tend to overheat and the exhaust valves run too hot and cause pinging.

A three-valve head with two intakes is much more practical. It also allows better squish and a place for dual spark plugs. This design was a study. There is no rocker or valve actuation to go with it.
