Who knows the working principle of the rotor engine and the diagram!

1. Generally, the engine is a reciprocating motion engine. When working, the piston makes a reciprocating linear motion in the cylinder. In order to convert the linear motion of the piston into rotational motion, the crank connecting rod mechanism must be used.The rotor engine is different. It directly converts the combustion expansion force of combustible gas into driving torque.

2. The principle of the rotor engine is to use the triangular rotor rotation to control compression and emission, and convert the combustion expansion force of combustible gas into driving torque.

3. Working principle: Generally, the engine is a reciprocating motion engine. When working, the piston makes a reciprocating linear motion in the cylinder. In order to convert the linear motion of the piston into a rotary motion, the crank connecting rod mechanism must be used. The rotor engine is different. It directly converts the combustion expansion force of combustible gas into driving torque.

4. The working principle of the engine is to directly convert the combustion expansion force of the combustible gas into driving torque. Compared with reciprocating engines, the rotary engine eliminates useless linear motion, becauseThis rotary engine of the same power is smaller in volume, lighter in weight, and lower in vibration and noise, which has great advantages.

Car whole vehicle structure recognition diagram

As shown in the following figure, the name of the exterior part of the car. 2: As shown in the figure below, the name of the internal structure of the car.

As shown in the figure below, the name of the exterior part of the car. 2: As shown in the figure below, the name of the internal structure of the car. Specific analysis of the structure of the car: total length: the maximum length of the car body (the distance between the front and rear outermost ends). Total width: the maximum horizontal size of the car body. Total height: the distance between the highest point of the vehicle and the ground.

A car is a complex machine composed of thousands of parts, integrating electrical, hydraulic, mechanical, bionic technology and other technologies. According toThe general structure and functions of each part of a car usually consists of four parts: engine, chassis, body, ancillary electrical appliances and electronic equipment.

As follows: Car leaf plate Car leaf plate, also known as wing plate, is located outside the body of the wheel, which can be said to be a covering part. It can not only reduce the wind resistance coefficient when driving according to aerodynamics, but also greatly help the stability of the car.

What types of airplane engines are there?? What is the working principle of each type? It's better to have a picture and an explanation...

The first type, a piston aircraft engine. The aviation engine used in airplanes or helicopters in the early days was used to drive propellers or rotors. Low-power piston aviation engines are widely used in light aircraft, helicopters and ultra-light aircraft. The second type is a gas turbine engine. The most widely used.

The first category is a piston engine, which is the same as a car engine in principle. The second category is gas turbine engines, which include many types, vortex injection, vortex fan, vortex paddle, vortex shaft, paddle fan, stamping.They all belong to the same category. The only difference is that the intake method and the method of doing work are different.

It is a reaction engine. Rocket engines take a famous Newton's law as the basic driving principle, which holds that "each force has a reaction force of equal magnitude and opposite direction". The rocket engine throws matter in one direction, resulting in a reaction force in the other direction.

Some are vertical. The scroll shaft engine is to add a shaft to the turbine rotor on the turbine engine, and the turbine rotor rotates to drive the hinge shaft to rotate. Such engines can only be arranged in parallel to ensure the intake of the turbine. The active shaft drives the rotor shaft perpendicular to it through the transmission device, and drives the tailblade shaft.

Principle of turbojet engine: turbineThe jet engine, abbreviated as the vortex engine, is usually composed of an intake duct, a compressor, a combustion chamber, a turbine and a tail nozzle. There is also a power combustion chamber between the turbine and tail nozzles of some military engines. The vortex injection engine is a thermal engine, and the work principle is also: input energy under high pressure and release energy under low pressure.
