Abstract
A combustion chamber for an internal combustion engine is provided which includes a cylinder head body having at least one generally dome-shaped combustion chamber defined by a lower surface of the body and having an intake side and an exhaust side, and a spark plug bore disposed in the combustion chamber so that when a spark plug is engaged in the bore, the dome-shaped portion is provided with an upper surface configured to shelter the electrode from direct impingement of a fresh charge introduced into the combustion chamber through the intake side.
