Description

Area of ​​application

[0001] The toothed-gear motor is a rotating internal combustion engine. It can be used to power motor vehicles, aircraft, ships, machines, and other equipment. State of the art

[0002] The internal combustion engines currently produced in very large quantities and used in the aforementioned applications mostly consist of a piston and crankshaft, with the piston performing a linear motion. This requires the piston to constantly change direction, which consumes a great deal of mechanical energy. This reduces efficiency to around 35%. To improve this effect, various rotary piston engines were developed. In this principle, a rotary piston performs a rotating motion, eliminating the need for the piston to change direction. However, these engines have not been able to gain widespread acceptance due to complex manufacturing processes and, in some cases, even lower efficiency.

[0003] The toothed-piston motor makes it possible to combine the advantages of a rotary piston motor with the simple manufacturing process of a linear piston motor. This means that there are essentially only two power transmission components up to the output shaft.

[0004] In a toothed-flank engine (ZM), two spur gears mesh with each other and, as they roll tooth by tooth, form the space for the fuel gas, the compression chamber, the combustion chamber, and the expansion chamber. The two gears are located in a sealed housing, like a gear pump. However, the ZM rotates in the opposite direction. The so-called squish chamber becomes the combustion chamber.

[0005] A fuel-air mixture is stored in the pre-chamber. The exhaust gases are discharged into the post-chamber. 1. Inflow

[0006] A combustible gas mixture (fuel-air mixture) is stored in the prechamber, which is largely formed by the housing. This mixture is processed externally and pumped into the prechamber at overpressure. The gaps between the teeth absorb the gas, resulting in the "first inflow." Fig. 2. Enclosing and compacting

[0007] The tooth of the opposite gear encloses and compresses the gas mixture through contact between the opposing tooth flanks. "2. Enclosure and compression" Fig. 3. Full compression and ignition

[0008] As the wheels continue to rotate, the combustion chamber is formed between the tooth tip and root, which is sealed by the tooth flanks. "3. Full compression and ignition" Fig. 4. Working stroke

[0009] If the gas is now ignited, either by self-ignition or external ignition, an explosive expansion occurs in the combustion chamber, which pushes the tooth out of the gap. “4th working stroke” Fig.4

[0010] This creates mechanical energy, which is captured by the bearing shafts of the gears. This principle creates a very even energy flow. A combustion chamber forms between each tooth and each gap, in which new mechanical energy is released when the compressed gas is ignited. 5. Outflow

[0011] The exhaust gases then flow from the system into the after-combustion chamber. "5. Outflow" Fig.

[0012] This is also mainly formed by a housing and is intended to include additional devices for environmentally friendly exhaust gas treatment.
