Eaton Char-Lynn Motor – Double Eccentric Rotor Motor: Sport Features
Eaton Char-lynn Motor Description: The double eccentric rotor motor is also known as the Miller cycle motor. It uses triangular rotor rotary motion to control compression and emissions, which is quite different from the linear motion of a conventional piston reciprocating motor. The following describes its application characteristics:
This kind of motor was invented by the German Fergas Wankel. Based on summarizing the research results of the predecessors, it solved some key technical problems and successfully developed the first rotor motor.
The movement characteristics of the Wankel rotary motor are: while the center of the triangular rotor revolves around the center of the output shaft, the triangular rotor itself rotates around its center. When the triangular rotor rotates, the inner ring gear centered on the center of the triangular rotor meshes with the gear centered on the center of the output shaft, and the gear is fixed on the cylinder without rotation, and the ratio of the number of teeth of the inner ring gear to the gear is 3:2. The above motion relationship makes the trajectory of the apex of the triangular rotor (ie, the shape of the cylinder wall) resemble an “8” shape. The triangular rotor divides the cylinder into three independent spaces, and each of the three spaces successively completes intake, compression, work and exhaust, and the triangle The rotor rotates one revolution and the motor is ignited three times. Due to the above motion relationship, the output shaft speed is three times the rotor rotation speed, which is completely different from the 1:1 motion relationship between the piston and the crankshaft of the reciprocating motor.
In a reciprocating motor, the piston reciprocates linearly in the cylinder during operation. In order to convert the linear motion of the piston into a rotary motion, a crank-link mechanism must be used. The rotor motor is different, it directly converts the combustion expansion force of the combustible gas into the driving torque. Compared with reciprocating motors, the rotor motor eliminates useless linear motion, so the same power rotor motor is smaller in size, lighter in weight, and has lower vibration and noise.
The main reason why the Wankel rotary motor cannot be widely used is that it can only increase the power significantly, while the low-speed torque is unacceptably low. Since the Wankel rotary motor is directly contacted with the main shaft by the rotor to drive the main shaft to rotate, the force of the gas on the rotor is converted into the torque output of the motor through the eccentric journal of the main shaft, and the eccentricity of the eccentric journal of the main shaft of the rotor motor Very limited, this is the root cause of the low torque of the Wankel rotor motor, and the main reason why the Wankel rotary motor cannot be widely promoted. At the same time, the shape of the Wanker rotary motor combustion chamber is not conducive to the complete combustion of the fuel, the flame propagation path is longer, so that the fuel and oil consumption is increased, showing a higher fuel consumption rate. Moreover, when the Wankel rotary motor is at a high compression ratio, the combustion chamber becomes too narrow and the flame cannot propagate normally. This is destined to use only the ignition type, and the compression ignition type, that is, the diesel cannot be used.
The triangular rotor motor drive shaft adopts a double eccentric mechanism, so that the motor volume is nearly doubled in the same rotor shape as the Wankel rotary motor, and the equivalent eccentricity of the drive shaft is about the same. 2.17 times. When the rotary motor is used as a gasoline motor, the combustion chamber volume is greatly increased, and the fuel combustion is more sufficient; when the diesel motor is used, the combustion chamber is not too narrow, so that it can be compression-ignited. At the same time, due to the multiplication of the equivalent eccentricity of the motor drive shaft and the increase of the gas pressure, the output torque of the motor is increased several times to meet the needs of the civilian vehicle.
