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 carankshafts 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.
