STARTING AID FOR A COMBUSTION ENGINE

摘要

A starting aid for a combustion engine comprises a hollow elongated body and a refractory electrical heating element mounted in the body at one end thereof. Formed in said one end of the body are one or more holes through which, in use, the heating element can be exposed to the combustion mixture of an engine. In addition, the body is formed with at least one exhaust aperture which is spaced from the heating element in the direction of the other end of the body and which permits the escape of gases entering the body through said one of more holes. Extending through the body and electrically connected to the heating element is an electrode rod for supplying heating current to the heating element to raise its temperature. The electrode rod includes two relatively movable parts which are mechanically connected by resilient means to maintain the heating element in compression against said one end of the body and which are electrically connected by a flexible braid. A heat resistant, gas restricting packing layer is mounted between the body and the electrode rod intermediate the ends of the body to allow free axial movement between the electrode rod and the body and substantially prevent gas flow past the packing layer.
