A rotary engine, parts thereof, and methods associated therewith is provided. The engine is modular and adjustable to accommodate a variety of requirements and preferences. The system includes a combustion assembly having a housing and a power rotor positioned therein. The power rotor rotates in a first direction from the beginning of each combustion process through the end of each exhaust process. The system also includes a compression assembly linked to the combustion assembly such that the compression rotor rotates in the first direction from the beginning of each intake process through the end of each compression process. A tank assembly in fluid communication with the compression assembly and the combustion assembly provides stability to the system while eliminating or otherwise reducing transitional loses.

A two stroke internal combustion rotary engine (30) with Zindler curve eccentric ring gear (8) and method of working of a two stroke internal combustion rotary engine (30) with Zindler curve eccentric ring gear is disclosed. The engine (30) has an equilateral triangular rotor (7) with Zindler curve shaped eccentric ring gear (8) with teeth. Output shaft (12) is fixed about to the center of the engine (30) with a center spur gear and it also connected to same sized another one or more spur gear (10) on the side of the center spur gear (11). When engine (30) start working, the rotor (7) and eccentric ring gear (8) will rotate eccentrically along with the side spur gears (10) connected to it, by running over the teeth cuts. Engine cover (16, 17) has a hole (20, 21) to allow a coolant to enter the rotor (7) and excel the heat.

A method and apparatus according to the invention is described, which in a first mode operates as an internal combustion engine delivering energy and in a second mode operates as a pulsed compression reactor converting electrical energy in the form of chemical compounds. In the second mode, at least one of the generated compounds is collected and temporarily stored.

A control device prevents damage due to backward rotation of a rotary engine and prevents misjudgment of backward rotation of the rotary engine. The control device for a rotary engine includes a motor mechanically connected to the shaft of the rotary engine, a controller (a motor ECU) that performs energization control of the motor to start the rotary engine by driving the motor, and a sensor (such as a motor rotation sensor). When starting the rotary engine, the controller stops energization to the motor based on an electric signal from the sensor when the shaft of the rotary engine rotates backward a predetermined angle or more, and then the shaft of the rotary engine continues to rotate backward for a predetermined time.

Closing timing of an intake port is changed without using a variable valve timing mechanism. An electric vehicle includes an engine for electricity generation in which closing timing of an intake port maximizes intake air charging efficiency in a specific revolution speed region, a sensor which outputs a signal related to a revolution speed of the engine, a controller which drives the engine at a revolution speed based on the signal of the sensor, a requested electricity generation amount being satisfied at the revolution speed, and a motor which applies a positive or negative torque to the engine. When the engine is driven in a revolution speed region other than the specific revolution speed region, the controller uses the motor to apply a positive or a negative torque to the engine in an intake stroke to change the closing timing of the intake port to increase intake air charging efficiency.

The invention provides an engine for obtaining kinetic rotational energy from the explosive decomposition of individual cartridges of an energetic material. The cartridges are individually ignited as needed, producing a bolus of hot, expanding gas, the energy of which is captured by a piston moving in a circular track. Each cartridge ignition produces a single circuit of the piston around the track. A gearing mechanism transfers the angular momentum of the piston to a flywheel. The engine may be coupled to an electrical generator to form a portable, on-demand electric generator system.

The disclosure provides rotary machines that include, in one embodiment, a shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first gearbox disposed thereon defining one or more cavities therein. At least one contour is slidably received into an arcuate cavity in an exterior surface of the gearbox. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume. A gearbox mechanism consisting of gears, crankshafts, bearings and connecting rod creates an oscillatory motion 2 times per revolution such that the contour can navigate about the arcuate cavity without contacting the cavity at a high rate of rotating speed. Thus, said working volume can expand and compresses twice per rotatable shaft revolution.

An apparatus including a first piston member rotatable about a first rotational axis and a rotor with a first chamber and pivotable about a second rotational axis. The first piston member extends across the first chamber. The rotor and first piston member are rotatable around the first rotational axis, and the rotor is pivotable about the second rotational axis to permit a relative pivoting motion between the rotor and the first piston member linked to the rotor rotating about the first rotational axis.
