Internal Combustion Engine With Arced Connecting Rods

US Patent:
5870979, Feb 16, 1999
Filed:
Jul 14, 1997
Appl. No.:
8/892161
Inventors:
John A. Wittner - West Chester PA
International Classification:
F02B 3306
US Classification:
123 524
Abstract:
An improved crankshaft connecting rod mechanism provides altered reciprocating motion of a piston attached to the connecting rods. The basic mechanism includes two, geared-together, counter-rotating crankshafts which are transversely aligned along parallel axes of rotation and symmetrically spaced apart. Two connecting rods are similarly aligned and have both ends on one side of the axis of linear reciprocation of a connected piston. The shafts of the two connecting rods are preferably displaced ("bent" in the lateral profile) toward the centerline. This bend in the connecting rod shafts may be of such a magnitude that they overlap during a portion of their motion by nesting together, utilizing male/female profiles on their inner side surfaces. The big ends of the two connecting rods may also be constructed so that they overlap. The connecting rods may have an arced profile that may be designed to flex during tension and compression during the reciprocating cycle of the piston.
