longcases, If I understand it correctly, Waukesha was licenced to use the Case block and modify it to use Waukesha parts. The compression ratio of 6:1 is even lower than some gasoline engines so I take it that by injecting the fuel, the idea was to deliver a finer mist within the combustion chamber than what a carburetor could provide. I'm puzzled as to why such a low compression ratio was used. It would seem a higher ratio would be advantageous.
Don L. Would you have some technical info that you could share?
