Abstract
A torch chamber apparatus and method for providing a more thorough combustion of a fuel/air mixture in a combustion chamber of a cylinder of an internal combustion engine. The torch chamber is configurated as a hollow, cylindrical body having a jet nozzle and external threads at a first end and an axial, internally threaded, spark plug-receiving opening at the second end. A diametrally enlarged shoulder, wrench engagement nut with an indicia thereon is also included at the second end. The dimensions of the hollow cylindrical body and the shoulder are selectively predetermined to adapt the torch chamber to be inserted into a spark plug access bore with a deformable gasket sealingly engaged between the shoulder and the rim of the access bore. The method includes interposing the torch chamber between the spark plug and the combustion chamber while aligning the jet nozzle inside the combustion chamber by viewing the indicia.
