We will now describe the operation of the engine.

The turbocharger 37 takes in air through its air intake port 38 and discharges the air. Partially pressurized air is supplied into the air intake passage 36 through the air outlet 36a. Ru. Adjacent to this passage, the piston is at or near bottom dead center and When the motor 27 rotates (clockwise in FIG. 1), air is forced into the piston 31. As they approach top dead center, they are compressed.

The pressurized air is exhausted from the housing through air exhaust passage 39 and It passes through a connection manifold 41 and passes through a one-way valve 42 to be supplied to the combustion chamber 40 .

.

A portion of the air, for example 18%, is fed into the ignition chamber 47 where one or more It is mixed with the fuel supplied by the upper nozzle 50. Air/fuel mixture ignites and the burning gas passes through the perforated wall 48 to the remaining air in the outer chamber 43. mixed with air. The burning combustion gases then create a water wheel effect in Loku 27. The combustion gases are returned into the housing 10 through a combustion gas inlet passageway oriented such that the combustion gases enter the housing 10.

The combustion gases drive rotor 27 in two ways. First, inside the cylinder 28 The gas expansion at pushes the piston 31 toward the bottom dead center and rotates the loco . At the same time, the gas is connected to the side of the cylinder so as to drive the rotor in the manner of a turbine. engage. (In the modification shown in FIG. 4, the teeth 85 are formed around the rotor 27. and these help to lock the rotor and the gas and drive it in the manner of a turbine. The holes 86 in the rotor (which create turbulence) cooperate with each other to create a turbulent flow. ) At or near bottom dead center, the energy from the scraps begins to drive the rotor. When the gas is obtained, the gas is discharged to the turbocharger 37 through the gas discharge passage 53. It drives it to pressurize the air that exits and enters the engine. (Roku episode During a short portion of the rotation, the incoming pressurized air transports the remaining combustion gases into the cylinder. Each cylinder 28 has an air intake passage 36 and a gas Both will be in communication with the discharge passage 52. ) The pistons are facing each other. The force required by one piston of the pair to compress the incoming air is would be provided by the expansion of the combustion gases acting against the other piston of .

The rotational motion of the rotor, which is half the speed of the crankshaft 24, is 2:1 of the transmission system 18 through gears 55, 56 giving a reduction ratio of The force is transmitted to the shaft 57. (For example, when the input shaft 57 is 6000 rpm When rotating, the rotor 27 rotates at 12000 rpm and the l crankshaft The shaft 24 is rotating at 24,000 rpm. ) From now on, the engine will operate the variable speed transmission assembly at a constant speed. For example, the input shaft 57 is driven at 2000 rpm. Let's write this assuming that it is. At rest, both sun gears are driven by the shaft. be moved.

The lowest speed at which the drive gear 72 can rotate is the step of the second planetary gear set 67. Down ratio (determined by the relative relationship of the teeth on the sun gear 67 and ring gear 71) The rotation of the ring gear 65 is determined by the sun gear 67 and the ring gear 7. The binion carrier 69 of the second planetary gear set 68 is rotated to provide a drive between make it turn

When the drive gear 72 starts rotating, it drives the driven gear 73 and the gear 73 has its spring connection, so the binions 77 and 80 (crown gear 7 (interconnected by 8). The spring loaded hub 83 is An additional delay is introduced before gear 82 begins to drive binion carrier 63. simultaneous At this point, the ring gear 86 supporting the cage 76 begins to rotate. Drive gear 72 and - When the rotational speed of the power shaft 60 increases to the rotational speed of the large force shaft 57, The rotational speed of the binion carrier 63 is such that the first planetary gear set 61 increases until locked to provide direct drive. At the same time, the ring gear 84 The binion carrier 69 is rotated at the same speed as the sun gear 67, and the second planetary gear center The same speed is reached to engage ring gear 65 so as to lock rod 8. Input and 57.60 now rotates at the same speed.

When a sufficient load is applied to the output shaft 60 to slow it down, the drive gear 7 The reduced rotational speed of 2 is sensed by the differential assembly and therefore the ring gear 8 4 and drive gear 82 rotate more slowly, releasing the planetary gear center and causing them to With stepped-down ratios that give the high output torque needed to satisfy the load. enable it to operate. When the load decreases, the rotational speed of the output shaft 60 is The upper throat of the planetary gear will rise until it is locked again.

This variable speed transmission system is for use on heavy vehicles or locomotives. , or when the engine is at a constant speed, e.g. high speed in almost pure turbine mode. Particularly suitable when configured to operate in (In the latter application, The loco 27 will have the outer contour shown in FIG. ) The specific examples shown are for illustration only. For example, an engine can be cooled with water. , and can have oil cooling for the rotor, and the cylinder 28 can have oil cooling for the rotor. The connecting rod 33 of each piston can be made in a straight line around the motor 27. It can be moved to one side. In transmission systems, spring negative Load hub 74 connects ring gear 68 and drive gear 72 to output shaft 60. It can be provided for the purpose of

Various other changes and modifications may be described and illustrated without departing from the scope of the invention. can be added to the specific examples given.
