摘要： A spark ignition engine device adapted for use with a pump. The engine is mounted on a mounting structure. The engine has a magneto flywheel for generating an ignition current and a high-voltage ignition coil means electrically connected by a first conductive wire means to the magneto. A conductive shield covers the first wire means and is grounded. The spark plugs are electrically connected by a second conductive wires means to the coil to deliver a high-voltage spark to the engine. The second wire means is also covered by a conductive shield covering and the shield is grounded. A control box is provided and grounded to the mounting structure. The control box is positioned to enclose the coil means and to receive the shielded first wire means. The box has a capacitor means grounded to the box and connected to said shielded first wires to prevent reverse flow of EMI to the magneto.

摘要： 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.

摘要： A system supplies compressed air and foam to produce a fire stream comprising an aerated foam. The system includes a fire pump, an air compressor, a mixer, and a controller for automatically maintaining a desired ratio of air and water delivered from the mixer to a fire stream delivery device. An electronic control unit is arranged to sense both the flow rate of the water delivered by the fire pump and the air flow rate delivered by the air compressor, and modulates an air pressure signal used to vary the flow of air to the inlet of the air compressor so as to hold the air flow rate and the water flow rate at the desired ratio.
