Abstract
An internal combustion engine is shown as including an annular or ring type cylinder and reciprocating piston therein; exhaust ports from the cylinder lead to an afterburner section situated generally medially of the annular cylinder; the exhaust gases from the annular cylinder are further burned in the afterburner section; at least one crankshaft is employed for connection as through connecting rods to the reciprocating piston; in one form a single crankshaft is employed and sliding guides are employed for precluding the occurrence of piston slap while in another form two parallel crankshafts are employed with both crankshafts being connected to the same piston; the crankshafts are shown as having large live bearing surfaces journalled in the cooperating portion of the engine housing.
Claims68
An internal combustion engine, comprising an engine housing, an annular cylinder with a combustion chamber formed in said housing, said annular cylinder comprising a first radially inner annular wall and a second radially outer annular wall, a ring-like piston received in said annular cylinder for reciprocating movement therein, and motion transmitting means operatively connected to said ring-like piston for transmitting the power developed by the reciprocating movement of said ring-like piston to associated output power consuming means, said motion transmitting means comprising crankshaft means and connecting rod means, said connecting rod means being effective for operatively interconnecting said ring-like piston to said crankshaft means, said crankshaft means comprising a large diameter live bearing portion journalled within said engine housing, said connecting rod means comprising at least first and second connecting rods, said first connecting rod being operatively connected to said crankshaft means at a first axial end of said large diameter live bearing portion, and said second connecting rod being operatively connected to said crankshaft means at a second axial end of said large diameter live bearing portion opposite to said first axial end.
