Cycloid rotor engine

Abstract

The invention relates to a cycloid rotor engine, which consists of a plurality of casings arranged in parallel to form a stator assembly, and a cycloid mechanism arranged inside forms a rotor assembly. In the cycloid mechanism, an elliptic rotor is arranged in a round disc member with a triangular cavity, and when the elliptic rotor and the member with the triangular cavity rotate with the angular velocity of 3:2 by taking respective central point as the axis, capacities of three cylinders change periodically; and a rotor air channel as well as an upper casing and a lower casing form a ventilation channel, and ignition is realized by a casing spark plug or a thermal lag time coil on the rotor, thereby forming a four-stroke engine in continuous rotation without a linkage mechanism or a gear mechanism.

Description

a technical field [0001] The invention relates to a cycloidal rotor engine, in particular to a vibration-free, high-speed, high-torque, high-power engine composed of an elliptical rotor and a triangular cavity component rotating together. Two background technology [0002] Among the existing engines, the ones with more mature technology are mainly reciprocating piston engines and Wankel triangular rotor engines for vehicles. Among the above two types of engines, the reciprocating engine has been designed and improved for more than one hundred years, and there are several problems that cannot be changed. 1. The engine uses the reciprocating motion of the piston for energy conversion, so the limit speed of the engine is low, and the energy lasts for 180 degrees when the crankshaft rotates 360 degrees. 2. All reciprocating engines are provided with a ventilation valve mechanism, which not only increases the volume of the whole machine, but also increases the weight of the whol...

AI Technical Summary

Problems solved by technology

1. The engine uses the reciprocating motion of the piston for energy conversion, so the limit speed of the engine is low, and the energy lasts for 180 degrees when the crankshaft rotates 360 degrees

2. All reciprocating engines are equipped with a ventilation valve mechanism, which not only increases the volume of the whole machine, but also increases the weight of the whole machine

3. The reciprocating engine uses the crankshaft and connecting rod for power output. When the piston is close to the top dead center and the bottom dead center, the effective arm of this output is very small, so that the expansion force in the cylinder cannot be fully exerted, and the energy conversion rate very low

4. When the reciprocating engine is ignited, the ignition timing needs to be very precise, otherwise it is easy to be too early or too late, resulting in a reduction in the power of the whole machine

1. The rotor in the triangular rotor engine rotates eccentrically during the working process, so there will be a lot of vibration when the engine is working

2. The cylinder shape of the triangular rotor engine is crescent-shaped, which is composed of a triangular rotor and an elliptical outer wall. This shape is not conducive to the combustion of gas

3. The compression ratio of the rotary engine is small, and compression ignition power cannot be used

4. The sealing of the triangular rotor engine is difficult and the processing is not easy

5. When the engine is working, the pressure of the expanded gas in the cylinder is decomposed, and the effective torque is very small, so that the energy conversion efficiency of the engine is lower than that of the reciprocating engine. , so general heavy equipment or off-road vehicles cannot install this type of engine, only high-speed racing cars or aircraft can be used, making it difficult to promote
