A two-stroke, two-cylinder internal combustion engine for use in portable applications has a cylinder head design, a fuel injection system and an ignition system which enables the engine to start and run on a fuel such as JP5 or DFM.

Internal combustion engine

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.

Portable engine-pump assembly

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.

A socket assembly for a ball and socket coupling comprises a socket body having a ball-receiving socket which includes a cylindrical portion. A pair of slots extend through the socket body and open into the cylindrical portion at locations diametrically opposite each other and outwardlyfrom the seated position of the ball. Each slot has a flat surface which generally faces the seated position of the ball and converges inwardly toward the axis of the cylindrical portion of the socket, thus to lie obliquely to the axis of the cylindrical portion. A generally C-shaped spring clip wraps around the socket body. The clip has opposed end portions which extend through the slots and part way into the socket far enough to engage the neck of the ball component. The end portions of the clip are oriented generally obliquely to the axis of the socket. The socket body has a pair of external flat surfaces which underlie the clip, and the clip has flat portions which engage the flat faces of the socket body to keep the clip from turning out of proper position to permit the socket assembly to be pressed onto the ball component.
