Abstract

Rotary vane internal combustion engine comprises of two side-by-side rotors, placed in a cylindrical housing, wherein each rotor has at least two radial vanes rigidly attached to the rotor that form chambers for intake, compression, combustion, and exhaust. Each rotor alternately engages with a shaft by overrunning one-way clutches and is held from turning back, through the damper, mounted on a corresponding flywheel and forming a part of the flywheel assembly, which is rigidly attached on the shaft. The assembled rotors from the outside are rigidly closed by flanges on each of which is mounted at least one blade. The blades are positioned into formed cavities between the rotors and caps of the housing, thereby forming two cooling cavities through which coolant circulates around rotors through openings in the housing and through longitudinal grooves in the shaft. On the vanes are mounted cylindrical and conical seals, which remove the need for lubrication.

Dependent claims

A rotary vane internal combustion engine comprising:

a first flywheel assembly rigidly connected to a shaft and comprising a first damper;
a second flywheel assembly rigidly connected to the shaft and comprising a second damper;
a cylindrical housing;
a rotor assembly located in the cylindrical housing and comprising
(a) a pair of side-by-side rotors, wherein a first rotor of the pair of side-by-side rotors includes an at least two radial vanes, the at least two radial vanes of the first rotor extending over a second rotor of the pair of side-by-side rotors, and wherein the second rotor includes an at least two radial vanes, the at least two radial vanes of the second rotor extending over the first rotor;
and
(b) a pair of side-flanges, wherein a first side-flange of the pair of side-flanges is rigidly attached to the second rotor and closes off at least a part of a first side of the rotor assembly and wherein a second side-flange of the pair of flanges is rigidly attached to the first rotor and closes off at least a part of a second side of the first rotor;
wherein the pair of side-by-side rotors and the pair of side-flanges form an at least one set of four radially spaced chambers, and
wherein the at least one set of four radially spaced chambers cooperates with the cylindrical housing to form a corresponding at least one set of four radially spaced engine-compartments;
wherein each of the pair of side-by-side rotors alternately engages with the shaft by a corresponding one-way overrunning clutch of a pair of one-way overrunning clutches to rotate the shaft, in a forward direction;
wherein, during the first rotor's engagement with the shaft, the second damper couples to the second rotor for a time period comprising a first momentary duration and a first subsequent duration, such that (i) during the first momentary duration the second damper counters a deceleration of a forward rotation of the second rotor and (ii) during the first subsequent duration the second flywheel assembly forces the second rotor to continue rotating in the forward direction;
and
wherein, during the second rotor's engagement with the shaft, the first damper couples to the first rotor for a time period comprising a second momentary duration and a second subsequent duration, such that (i) during the second momentary duration the first damper counters a deceleration of a forward rotation of the first rotor and (ii) during the second subsequent duration the first flywheel assembly forces the first rotor to continue rotating in the forward direction.

A method of starting a rotary vane internal combustion engine comprising a cylindrical housing that includes an at least one set of four radially distributed segments comprising an intake segment (Is) having a fuel-mixture supply port, an exhaust segment (Es) having a gas-exhaust port, an ignition segment (Ss) comprising a spark plug and coupled to a first fuel-mixture inlet valve, and a compression segment (Cs) coupled to a second fuel-mixture inlet valve;

and
a rotor assembly located in the cylindrical housing and comprising an at least one set of four radially spaced chambers that rotatably align with the at least one set of four radially distributed segments of the cylindrical housing to form an at least one set of four radially spaced engine-compartments including an intake compartment (I), an exhaust compartment (E), an ignition compartment (S), and a compression compartment (C),
wherein the ignition compartment initially includes the ignition segment in alignment with a first chamber, the compression compartment initially includes the compression segment in alignment with a second chamber, the intake compartment initially includes the intake segment in alignment with a third chamber, and the exhaust compartment initially includes the exhaust segment in alignment with a fourth chamber;
the method comprising the steps of:
using the first and second fuel-mixture inlet valves to inject a fuel mixture into the first chamber and the second chamber, respectively;
using the spark plug to ignite the fuel mixture in the first chamber, thereby forcing rotation of the rotor assembly within the cylindrical housing such that the second chamber moves into alignment with the ignition segment, thus reconfiguring the ignition compartment to include the ignition segment and the second chamber with the fuel mixture therein;
and
using the spark plug to ignite the fuel mixture in the reconfigured ignition compartment, thereby forcing further rotation of the rotor assembly within the cylindrical housing.
