This invention relates to improvements in internal combustion engines. More particularly it relates to increased levels of usable electrical energy production and fuel efficiency within a relatively fixed speed, cam-track style Engine/Generator when combined with the secondary injection or injections of a rapidly expanding medium (usually water) into the engines combustion chambers during and after the combustion process has been initiated. The injection of said medium causing reduced fuel consumption, increased cylinder pressure, an extended usable piston stroke length, and increased usable energy production, while reducing the temperature of the combustion gases in order to control or eliminate the production of the pollutant, NOx and to further reduce thermal pollution exhausted into the atmosphere.

An improved internal combustion engine utilizes at least one orbital body with at least one orbiting rod journal offset and engaged in a specific way from the center of orbiting body. Further, orbiting body together with orbiting rod journal and one of the gears as one body, rotationally linked to the block via stationary second gear engaged in 1:1 ratio. Which transfers the rotation to main journal via flying arm. Such that radial motion of flying arm transfers the rotation to the main crankshaft axis and constitute one body. This results in a constant volume compression period of max. 60° , improving operation, efficiency and cleanliness of the engine.

An Engine with Isochoric Combustion has pistons arranged within cylinders, connecting rods connected to the pistons and to upper joints of triangle links, and a crankshaft with crankpins offset from the centerline of the crankshaft by crank arms. The triangle links are connected to the crankpins at additional joints of the triangle links. Radius links are pivotally connected to the engine by pivot pins at one end and to the triangle links at a further joint of the triangle links at their other end. By way of geometry of the linkages defined by the crank arms, the triangle links, the radius links, and the connecting rods, and by way of the relative positions of the crankshaft, the cylinders, and the pivot pins, during a crank angle segment, the Cylinder Volume during the combustion event is characterized by an extended dwell.

An internal combustion engine featuring a radial array of cylinders and pistons; the pistons having rods including cam followers engaging the surface of a cam drive to transfer reciprocating linear motion into rotary motion; wherein between the piston rods and the engine housing are disposed arrays of toothed rollers to provide a rolling interface.

A combustion engine is disclosed having a cylinder with a piston travelling through same, coupled by means of a piston rod to a crankshaft, wherein the piston rod has: a first hub in its head for coupling with the crankshaft; a second hub in its foot substantially aligned with or parallel to the first hub in the longitudinal direction of the cylinder when the crankshaft is in the upper or lower position; and a third hub in its foot, which is offset laterally towards the front with respect to the second hub in the direction of rotation of the crankshaft; the piston being coupled with the third hub, having a guide for the travel of the piston rod coupled with the second hub, and the piston being coupled with the third hub via a link rod.

Disclosed are four-stroke internal combustion engines and engine modules. The engine modules described herein convert linear reciprocating motion of a piston within a cylinder to rotational motion of a flywheel, which rotates around the cylinder's axis, or to rotational motion of the cylinder, which rotates within the flywheel. The linear reciprocating motion of the piston causes rotation of the flywheel or cylinder by piston pins being pushed down a sloped, spiraling surface of the flywheel, resulting in highly efficient power transfer. The rotational motion is transferred through a final drive, such as a drive shaft, drive train or drive chain. Engines described herein may include pairs of engine modules.
