Abstract: A method of controlling a rotary engine is disclosed. The rotary engine includes a shroud surrounding a rotor. The rotor carries a combustion chamber spaced from an axis of rotation of the rotor. A pressure activated valve is located between the combustion chamber and obliquely arranged exhaust nozzles. An ECU controls the combustion cycle of the engine based on a signal from a pressure sensor in the combustion chamber. The electronic control responds to the pressure signal from the pressure sensor to open a fuel control valve, to fire a spark plug and cause combustion of the fuel within the combustion chamber, and to thereafter open an air control valve to purge the combustion chamber of exhaust gasses.

Abstract: A split-cycle variable capacity rotary spark ignition engine system having at least a first rotary configuration (C1) including repetitively volume variable working chambers [60, 61, 62] for carrying out the combustion-expansion and exhaust phases and at least a second rotary configuration (C2) including repetitively volume variable working chambers (70, 71, 72) for carrying out the intake and compression phases of a four phase engine cycle. Dividing seal means (73, 74 of C1, 75, 76 of C2) for periodically dividing each of successive working chambers into a volume enlarging leading portion and a volume contracting trailing portion. Discharge valve means for varying compression chamber capacity through discharging fraction of trapped intake gas from compression chambers. A first phase altering arrangement is provided for varying the phase relation between the first rotary configuration (C1) and the second rotary configuration (C2). A second phase altering arrangement varies phase relation between the discharge valve means and corresponding compression chambers.

Abstract: In a cylinder dividing mechanism of a pneumatic tool, the first and second air pressure driving spaces are formed in the chamber, the first and second external channels are set externally on the circumferential wall, the first external channel is connected with the first air intake and air intake/exhaust dividing controller, and the second external channel is connected with the second air intake and air intake/exhaust dividing controller. As such, a single chamber is provided with two air pressure driving spaces for synchronous compression and driving of the rotor. The driving torsion for the pneumatic tool could be multiplied without need of increasing the volume of the chamber of the cylinder to cater for the need of the users with improved applicability.
