Engine with double sided piston

A lubrication system for a reciprocating dual piston engine having at least one dual piston mounted in at least one cylinder of an engine block, comprising:

• the at least one dual piston having a cylindrical portion and a rod portion;
• the cylindrical portion having a central portion between two end portions;
• the rod portion extending from the cylindrical portion;
• an oil flow means being adapted to direct oil in an oil cycle to the central portion;
• the oil flow means including an oil pump, an oil sump, at least one oil tubs and an oil reservoir;
• the oil pump being adapted to collect oil from the oil sump and deliver oil to the oil reservoir in order to permit at least one repeat of the oil cycle;
• the reciprocating dual piston engine having at least one dual piston;
• a cylinder drain aperture being situated in the central portion;
• the cylinder drain aperture cooperating with the oil flow means;
• the rod Portion including a hollowed-out channel rod;
• the hollowed-out channel rod communicating with the cylinder drain aperture;
• a rod aperture in the hollowed-out channel rod communicating with an oil reservoir;
• the oil reservoir communicating with the central portion;
• an oil pump being situated adjacent to the central portion;
• the oil pump moving oil from the oil reservoir into the central portion;
• the at least one cylinder having an oil intake port communicating with the central portion in order to receive oil;
• and
• the at least one cylinder having an oil exit port communicating with the central portion in order to remove oil.

An internal combustion engine having at least one cylinder with a reciprocating dual piston mounted therein, comprising:

• the at least one cylinder providing a combustion assembly housing;
• the reciprocating dual piston providing a set of combustion chambers within the at least one cylinder;
• the set of combustion chambers including a first sub-chamber and a second sub-chamber within the cylinder;
• the reciprocating dual piston dividing the at least one cylinder into the first sub-chamber and the second sub-chamber;
• a connecting rod, a clevises link, a connecting shaft, and a rod bearing cooperating with the reciprocating dual piston;
• the rod bearing being attachable to a crankshaft for a vehicle in order to provide power for the vehicle;
• a support lever having a first lever end and a second lever end;
• the first lever end being connected to the connecting shaft and the clevises link;
• the second lever end being connected to a bearing;
• the connecting rod having a connecting end attached to the reciprocating dual piston in the first combustion chamber;
• the first combustion chamber being closer to the crankshaft than the second combustion chamber;
• the connecting rod passing through a rod aperture in the first combustion chamber;
• a slide fitting and bushing cooperating to movably seal the rod aperture around the connecting rod in order to seal the first sub-chamber;
• the reciprocating dual piston and the connecting rod reciprocating in a substantially linear motion;
• the reciprocating dual piston simultaneously completing two separate strokes in two separate sub-chambers within the at least one cylinder;
• a transfer mechanism converting the substantially linear motion into a rotational motion;
• the transfer mechanism joining the connecting rod to a rotational motion of the crankshaft;
• a clevises link attaching to the connecting rod;
• a connecting shaft attaching to the clevises link with a dowel pin, a support lever, and a needle bearing;
• the piston having a central portion between two end portions;
• the connecting shaft rotating the crankshaft;
• a bearing attaching the connecting shaft to the crankshaft;
• and
• the central portion retaining oil therearound when the engine is shut off.
