I would like to know what injection advance is used and how turbulent the combustion chamber is on these engines?
Hp/cu in seems very low as compaired to automotive engines, yet effciency is high?
Yeah after compairing cylinder capacity to surface area, it is suprisingly better than an average auto engine.
I should have done that in the begining.
There are many things that add to make these engines effcient. Thanks for all the posts
