Abstract: An internal combustion engine of the opposed piston type valved by the passage of the pistons beyond inlet and outlet ports at opposite ends of the cylinders. The motion transmitting mechanisms for the opposed pistons are operable to move the opposed pistons within each cylinder through a successive three cycle repeating movement which includes (1) an operative power cycle, (2) a gas exchange cycle, and (3) an operative compression cycle. A pump assembly is associated with each piston operable to cause a fresh charge of gas to be displaced by the pump assemblies associated with the opposed pistons of each cylinder during an operative cycle of the associated pistons therein and confined to move directly into the open inlet port of one other cylinder generally simultaneously with the gas exchange cycle of the opposed pistons associated therewith so as to thereby effect the exchange of the combusted gases therein with a fresh charge under relatively low pressure conditions during a time period which is generally equal to the time of the operative cycle.

Abstract: An oscillating lever arm engine includes rigidly connected opposing pistons moved by a single lever connected to a rotating crankshaft. When applied to a two-cycle internal combustion engine, one piston may function as a pump piston and the second piston as a working piston which delivers power to the crankshaft through a connecting rod. When the pump piston is chosen to be of larger diameter, the volumetric efficiency of drawing in and providing the intake charge to the working piston may be increased. Furthermore, when poppet-type exhaust valves are used, valve timing may be selected so that the exhaust valves close before the cylinder wall transfer ports to achieve a supercharging effect.

Abstract: The present invention relates to a central combustion chamber engine consisting of an assembly formed by pistons that move from ends opposed to a combustion chamber, in which said chamber has intake and exhaust control means for the combustion gases (valves), ignition means or spark plug to induce the combustion of said gases and movement transmission means from the pistons activated by the expansion of the combustion gases in compression ratios similar to the ones of conventional internal combustion engines, towards the main engine shaft, which is located longitudinally along the same motor assembly, and rotates using sliding means, and achieving thus better operation performance, because it uses optimal pathways of the finite-time thermodynamic cycle, balance of the running engine and total symmetry with respect to the ignition point which will favor a more complete fuel combustion.

Abstract: A rotating cylindrical piston engine with a variable effective compression stroke. The present engine shuttles the piston during the power stroke as far as possible in the cylinder to maximize the use of the power provided by the fluid explosion. Since as much as possible of the explosion force is used, i.e., preferably until the exhaust gas reaches ambient temperature or pressure, the exhaust gas is cooler and thus the engine may need no external water cooling, allowing internal air cooling in the cylinder by intake air to be complemented by the cooling with the exhaust gas. Preferably, such linear motion of the shuttling piston over such a great length is converted to rotary motion by forcing the piston to spin in the cylinder as the piston is driven the length of the cylinder. The relative great length of the stroke of the piston captures a great amount of air during the intake stroke, and some of this intake air is expelled during the compression stroke to provide for an effective compression stroke such that the power stroke is of a greater length than the effective compression stroke. The present engine further includes a plate-like cylinder head, a plate like rotary valve, and plate like manifold to provide for a compact head arrangement. The present engine further includes a compression release port which may be opened during the power stroke to permit the piston to act like a brake relative to the power output shaft. The present engine further includes a track and rider arrangement for converting the linear shuttling motion of the piston into rotary motion. The present invention further includes a gear assembly between the piston and a power output shaft for transmitting the rotary motion of the piston to the power output shaft. The present engine further includes a fuel pump assembly, a timing assembly, and an engine isolation arrangement.

Abstract: In an axial-piston engine of the type known as a "wabbler" engine, in which the motion of the pistons is transferred to a straight main shaft by means of a non-rotating element (referred to as the "wabbler") which nutates as the shaft rotates and transfers the motion to the pistons via arms at its periphery, a design of the wabbler in which the wabbler is made in two or more parts so as to enclose a swashplate on the shaft, with thrust bearings between the wabbler and the swashplate (which latter is fixed to the shaft). The parts of the wabbler are rigidly connected together, so as to maximise the bending strength of the assembly in resisting the thrust loads from the pistons, and to facilitate the transfer of the loads to the bearing surfaces so as to avoid excessive localised loading of the bearings. To this end, the mating surfaces between the parts of the wabbler have features such as serrating or grooving which by interlocking action enhance the transfer of shear forces, such that the bending strength which would have existed had the wabbler been all in one piece is retained to the greatest possible degree.In this design, the body of the wabbler essentially consists of a short "cylinder" with heavy annular end plates; the spacing-apart of these ends provides a superior means of reacting the cantilever bean loads from the arms and of distributing these loads over the bearing surfaces.

Abstract: This invention relates to an Oscillating Drive Shaft (ODS) and related components that replaces the crankshaft of reciprocating piston engines. The ODS is positioned to the left and/or right of the piston/s line of travel. The distance of the ODS from the center line of the piston's direction of travel is determined by the design nee& of the engine. One or more arms/beams (depending on the number of pistons) are fixed on the ODS. These arms are then connected to the reciprocating pistons using a suitable medium (e.g. connecting rod or gears) so that the reciprocating travel of the piston imparts an oscillating or rocking motion to the ODS. The ODS then passes through ratcheted gears or ratcheted flywheel (depending on requirements), converting the oscillating/rocking motion into the desired rotary direction of travel.

Abstract: A low-pollution external combustion piston engine is adapted to utilize any of a number of expansible gases and fuels, and to maximize power output relative to the weight of the engine. The engine has a highly efficient and compact rotary design featuring a multi-cylinder rotary block acting on a rotary torque conversion plate. The design includes porting and valving for controllably admitting pressurized gas at substantially equal pressures to both sides of each piston to drive each piston bidirectionally and thereby maximize power output and efficiency. Each piston chamber has both primary and secondary exhaust porting to minimize back pressure and thereby further aid power output and efficiency.

Abstract: An air intake manifold assembly (20) includes an intake manifold housing (22), made of a light weight material, and a pressure relief disk (38). The pressure relief disk (38) is mounted over a relief disk hole (26) in the housing (22). The pressure relief disk (38) engages the housing (22) to form a seal during normal engine operation. Should the manifold assembly (20) experience an induction backfire, pressure relief disk (38) includes a feature (52) that will rupture at a predetermined positive pressure, thus allowing for escape of the air while minimizing the potential for damage to the housing (22) and other components on the engine that are near to the intake manifold assembly (20).
