High efficiency combustion chamber system

An improved combustion chamber system for use with an internal combustion engine having at least one cylinder each having a piston and a cylinder head forming a combustion chamber therebetween, which comprises:

• three valves in the head at each combustion chamber, the valves substantially uniformly arranged around the axis of the cylinder;
• two of the valves having substantially equal areas and adapted to act as intake valves;
• the third of the valves having an area substantially equal to, or slightly greater than, the area of one of the intake valves, the third valve being adapted to act as an exhaust valve;
• and
• the head having three approximately hemispherical recesses, each of the recesses housing one of the valves.

An improved combustion chamber system for use with internal combustion engine having at least one generally planar piston surface cooperating with a recessed combustion chamber in a generally planar cylinder head, which comprises:

• three valves in the head at the combustion chamber, the valves substantially uniformly arranged around the axis of the cylinder;
• two of the valves having substantially equal areas and adapted to act as intake valves;
• the third of the valves having an area substantially equal to, or slightly greater than, the area of one of the intake valves, the third valve being adapted to act as an exhaust valve;
• at least one spark plug for igniting an air/fuel mixture in the combustion chamber, said at least one spark plug located entirely within said cylinder head and combustion chamber without extending below the plane of the cylinder head;
• and
• three squish areas formed at substantially equally spaced areas around the combustion chamber, each squish area located along the combustion chamber periphery between two adjacent valves.

An improved combustion chamber system for use with internal combustion engine having at least one piston and a cooperating cylinder head forming a combustion chamber therebetween, which comprises:

• three valves in the head at the combustion chamber, the valves substantially uniformly arranged around the axis of the cylinder;
• two of the valves having substantially equal areas and adapted to act as intake valves;
• the third of the valves having an area substantially equal to, or slightly greater than, the area of one of the intake valves, the third valve being adapted to act as an exhaust valve;
• a single spark plug for igniting an air/fuel mixture in the combustion chamber;
• said single spark plug located at substantially the center of said combustion chamber.
