Method and apparatus for incorporation of a flame front—type ignition system into an internal combustion engine

摘要

A method and apparatus for installation and functioning of a flame front type ignition system in a throughbore through the wall of the head of an internal combustion engine. The flame front ignition system employs a flame cone which is thread ably inserted within the throughbore. The inboard end of the flame cone is provided with a plurality of exit ports opening from a central channel and into the combustion chamber. The flame cone is provided with indicia on its outboard face and a marker is provided on the outer rim of the throughbore. When an indicia letter on the flame cone is aligned with the marker, the flame cone is properly installed. The depth of insertion of the flame cone is adjustable by means of spacer washers adapted to selectively adjust the dept as well as seal the flame cone in the throughbore.
