[SEL] The McVickerish Engine

[Kangas, James G.]

Thank you Arnie and Patrick but I'm still a little puzzled. If neither the exhaust nor intake valve is opened at any time while the engine is missing wouldn't that be like a Diesel using it's Jacob brake? The compression without firing will stop the engine very quickly if it was not for the vehicle's momentum forcing the engine to keep turning over.

Crossley kerosene engines govern on not opening the fuel valve which means
no valves are open when they are missing.  My Bartram also works on not
opening the intake valve.
