<p>An internal combustion engine comprises a casing and a rotor rotatably mounted in the casing with a plurality of blades formed in the surface thereof. A power shaft is connected to the rotor and extends out of the casing. A plurality of circumferentially spaced nozzles in the casing are in line with the rotor blades and extend tangentially in a common direction towards the rotor. A combustion chamber has an outlet port in communication with the nozzles. There are exhaust ports in the casing between and aligned with the nozzles. The combustion chamber has an apparatus for supplying an explosive fuel mixture to the combustion chamber through the fuel inlet port thereof, a spark plug for firing the explosive mixture therein and a mechanism for supplying gas under pressure to the nozzles to start the rotor turning in the casing. The mechanism to start the rotor turning comprises a piston in the chamber normally urged towards the inlet port. The outlet port in the chamber is closed by the piston when the latter is in its normal position. The expanding gases of the fired charge force the piston to uncover the outlet port to permit gases to travel to the nozzles to start the rotor turning. There is a locking mechanism for sewing the piston in a lower position, uncovering the outlet port, when the engine has started.</p> |
