Abstract
An engine for a portable engine-pump assembly is designed to operate on a safe fuel such as JP5 or DFM. The engine is started by a starting fuel such as propane which is supplied to the engine from a pressurized propane-containing cartridge. The propane starting system uses a puncturing device which has a built-in check valve function to isolate the propane system from moisture and contaminants in the air.
