Abstract:
Disclosed are four-stroke internal combustion engines and engine modules. The engine modules described herein convert linear reciprocating motion of pistons to rotational motion of a flywheel, which rotates around the axis of an engine block, or to rotational motion of the engine block, which rotates within the flywheel. The linear reciprocating motion of the pistons cause rotation of the flywheel or engine block by piston drive 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.

Abstract:
A radial cam engine with an optimized cam configuration can provide improve performance over crankshaft internal combustion engines. The cam configuration can include a flat-top or flat bottom piston motion, multiple lobe cam configurations, matching piston force with torque/force ratio in combustion phase, asymmetry piston motions for improved power transfer during combustion phase, and/or offset piston and cam configurations. The radial cam engine can be used in vehicles, such as hybrid vehicles.
Abstract:
A crankshaft for an internal combustion engine may include first and second journals having circular cross-sections, wherein the first and second journals define a longitudinal crankshaft axis. The crankshaft may further include a crankpin defining a longitudinal crankpin axis and being configured to be coupled to a connecting rod, the crankpin extending between the first and second journals, such that the longitudinal crankpin axis is parallel to the longitudinal crankshaft axis. The crankpin may include at least one crankpin journal and at least one cam including a cam profile, wherein the cam profile is configured to affect the stroke of a connecting rod coupled to the crankpin. A connecting rod may include a follower configured to follow a cam. An internal combustion engine may include a crankshaft and a connecting rod configured to provide relative linear movement between a crankpin axis and a proximal end of the connecting rod.

Abstract:
The present invention relates to a hybrid system that comprises: a multifunctional hybrid motor system with pistons, wheels, and associated means including in combination two motor cycles complementary in terms of technology and temperature, one defining an internal combustion engine (A) with at least three cylinders (c1, c2,c3) with pistons (p1,p2,p3), and the other defining a so-called external combustion engine (B) with at least three cylinders (c4,c5,c6) with pistons (p4,p5,p6) driven by the expansion of an active fluid, said hybrid motor system being formed so as to include at least three cylinder/piston pairs, wherein the internal combustion engine (A) operates according to a 4-stroke cycle while the external combustion engine (B) operates according to a 2-stroke cycle, said engine (B) does not include any valves, the pistons (p1,p2,p3, etc) of the internal combustion engine (A) and the at least three pistons (p4,p5,p6, etc) are arranged so that the energy resulting from the consecutive expansion of the active fluid in the at least three cylinders (c4,c5,c6 ) of the external combustion engine (B) acts consecutively on said pistons of said 4-stroke internal combustion engine (A) during the compression and exhaust phases. This technical solution makes it possible to recover a portion of the thermal energy discharged by the exhaust gases of the internal combustion engine in order to convert the same into mechanical energy in the external combustion engine.
Abstract:
An Otto cycle, Atkinson cycle or supercharged internal combustion engine (10) and a timing mechanism therefor. The engine comprising: a cylinder (14) and a piston (12) reciprocally mounted within the cylinder (14) in which reciprocating movement of the piston is converted into rotational movement of an output shaft (28) by way of rollers (20, 24) engaging primary (22) and secondary (26) cam means which are affixed to, and rotatable with, the output shaft (28). The timing mechanism comprising cam means (52, 53) mounted on, and rotatable in unison with, the output shaft (28), a cam follower (54, 55) arranged to engage the cam means (52) and a linkage connecting the cam follower to a pivoting rocker arm for actuating the engine's induction and exhaust valves, the rocker arm pivot being adapted to be moveable on an arcuate locus centred on the axis of the output shaft (28).
Abstract:
An internal combustion rotary piston engine (10) comprises a cylinder (12) housing a power piston (18) and a second piston (38) which is coupled to the power piston (18). A shaft (16) is coaxially supported in the cylinder (12) and is able to rotate along a longitudinal axis (14) that is fixed from translational motion along the axis (14). The pistons (18) and (20) are mounted on the shaft (16) in a manner where they can reciprocate along a shaft (16) and rotate with a shaft (16). A track and bearing system (20) couples the second piston (38) to the cylinder (12) and is configured to cause the second piston (38) and thus the piston (18) and shaft (16) to rotate as the piston (18) reciprocates along the shaft (16). The track (116) of the track and bearing system is formed with a radius which is greater than the radius of the power piston (18). The torque produced by the engine (10) can be varied by varying the radius of the track (116).

The cams, crank shaft, and expansible compressible connecting means are arranged so that a number of connecting means expand against the compression of one connecting means. The pressure bar is movable to position the rocker arms for a selected degree of connecting means compression.
