ENGINE IGNITION SYSTEM WITH AN INSULATED AND EXTENDABLE EXTENDER

Title:

ENGINE IGNITION SYSTEM WITH AN INSULATED AND EXTENDABLE EXTENDER

Document Type and Number:

WIPO Patent Application WO1986004480

Kind Code:

A3

Abstract:

An ignition system of an engine has a coil which is spaced away from an igniter to protect the coil from heat of a combustion chamber and combustion gas leakage. The electrical connections between the coil and igniter of current design practice have not performed satisfactorily due to loosening of connections, absorbtion of energy within the connectors and the escape of electrical energy. The present ignition extender overcomes these shortcomings by resiliently biasing a first electrical conducting core into contact with a source of high energy and a second electrical conducting core into contact with an igniter and insulating the first and second electrical conducting cores and a biasing and providng mechanism from the surrounding environment by surrounding them with a first and second telescopingly arranged insulating members. When included in an engine, the extender is combined with a shield to further protect and increase the functional life of the components.
