Internal combustion engine combustion chamber design and air/fuel mixture supply means

Claim 1

An internal combustion engine combustion chamber and air/fuel mixture supply means comprising: a piston means; a principal combustion chamber defined in part by said piston means and having a double-lobe configuration; a deflector forming part of and projecting from said piston means having a double-lobe configuration corresponding to that of said principal combustion chamber, having an inclined end surface and adapted to project into said principal combustion chamber; a precombustion chamber having a shape defined by a revolution torus in the form of a circle revolving about an axis contained in the plane of the circle at a radius approximately equal to one-half of the radius of the circle; a convergent-divergent nozzle interconnecting said principal and precombustion chambers and located on said axis; a hollow deflector supported in said precombustion chamber on said axis having the shape of a truncated cone with concave generatrix; means for providing separate supplies of air/fuel mixtUre to said principal and precombustion chambers and to provide individual qualitative control of the air/fuel mixture of each said supply; a spray means for spraying said supply of air/fuel mixture for said precombustion chamber into said precombustion chamber on said axis; a feeder means for controlling supply of said precombustion chamber''s air/fuel mixture, to said spray means; and an ignition plug extending into said precombustion chamber for igniting air/fuel mixture in said precombustion chamber.
