In-line cylinder head for internal combustion engine
This patent describes a cast cylinder head for an internal combustion engine using flat head pistons, the head including a flat mounting surface and having for each of several in-line circular piston areas: a wedge shaped combustion chamber extending from the mounting surface; a frusto-conical intake valve seat in the first cavity area having a major diameter circular edge surface and a minor diameter circular edge surface concentric with an intake valve axis; a frusto-conical exhaust valve seat in the first cavity area having a major diameter circular edge surface and a minor diameter circular edge surface concentric with an exhaust valve axis; a spark plug bore in the second cavity generally between the intake valve and the exhaust valve axis; intake passage means in the head for establishing fluid communication with the intake valve seat and exhaust passage means in the head for establishing fluid communication with the exhaust valve seat.
