Interdigitated rotor engine

Abstract

The invention relates to an interdigitated rotor engine. The complete machine comprises four shell components which are arranged side by side and fixed through bolts; in the three cavities of the inside of the rotor engine, the upper and lower cavities are used to hold a rotor assembly, and the middle cavity is used to hold a transmission system composed of an output shaft, an inner sleeve, an outer sleeve and a multiplex gear. By using the interdigitated rotor engine, power transmission can be realized and the alternate transposition and rotation of rotors can be realized so that the volumes of a plurality of cylinders composed of two interdigitated double-vane or four-vane rotors and the shell can change periodically. A gas port on one side of the rotor cavity is used for air admission and air exhaust, a spark plug on the other side is used for ignition, and the engine capable of performing continuous operation can be realized through four strokes.

Description

a technical field [0001] The invention relates to a cross-rotor engine, in particular to a high-power engine with rotors intersecting each other, without a crank and connecting rod mechanism, and a transmission system composed of a plurality of gears. 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. In the existing technology, the reciprocating engine for vehicles has been designed and improved for more than one hundred years, and the performance of the engine has reached the limit. If the performance is further improved, it can only be made with stronger materials. After more than one hundred years of improvement, there are several problems in this kind of engine that cannot be changed. 1. The piston of the engine adopts reciprocating type, and the vibration caused by inertia is inevitable. 2. The ventilation system of the engine is ...

AI Technical Summary

Problems solved by technology

1. The piston of the engine adopts reciprocating type, and the vibration caused by inertia is inevitable

2. The ventilation system of the engine is equipped with ventilation valves, camshafts and other components to increase the operating load of the whole machine, and at the same time increase the weight of the whole machine and increase the volume of the whole machine

3. The 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 is very low.

4. When igniting compressed gas, it is difficult to grasp the ignition timing. Too early or too late ignition timing will reduce the power of the whole machine

Fifth, when the piston moves in the cylinder, the friction between the piston skirt and the cylinder wall is very large, so that part of the fuel power is lost in the form of frictional resistance, resulting in a decrease in the energy conversion rate of the engine

1. The movement process of the triangular rotor inside the cylinder is eccentric rotation, so vibration is inevitable

2. The cylinder of the triangular rotor engine is composed of the outer wall of the rotor and the inner wall of the cylinder. Its shape is a crescent-shaped narrow space, so the flame propagation path is longer, which increases the consumption of fuel and oil.

3. The rotary engine can only use ignition type, not compression ignition type, that is, diesel oil cannot be used

4. The unique cylinder shape of this machine greatly increases the difficulty of sealing and processing, the manufacturing technology is high, the cost is relatively expensive, and it is difficult to promote

5. Due to the power transmission form of the triangular rotor, part of the expansion force of the cylinder drives the output shaft to rotate, and the other part points to the axis of the output shaft to make the gas expand and do work. Therefore, this type of engine cannot be installed on general heavy equipment or off-road vehicles, and can only be used in high-speed racing cars or aircraft, which limits civilian use.
