125c motorcycle scooter engine schematic

The engine principle of scooter is not substantially different from other types of motorcycle engines, but its transmission system It's different. Most of them are stepless variable speed belt transmission, and the working process is shown in the figure below.

The four-stroke motorcycle engine is mainly composed of fuselage components, crankshaft connecting rod mechanism, gas distribution mechanism, transmission mechanism, clutch and start mechanism, fuel supply system, lubrication and cooling system and other parts. Figure 1-65 shows the Lifan 125 motorcycle engine.

MotorcycleThe basic principle of the car's work is that the engine constantly generates heat energy. After the heat energy is converted into a rotational force through the crankshaft connecting rod, the rear wheels are driven by the variable-speed transmission device with rotational force. When the ground friction is overcome, the motorcycle can be driven.

working principle of two-stroke motorcycle engine

working principle of two-stroke engine: The working principle of two-stroke engine is that the piston moves up from the lower stop point. After the three air holes are closed at the same time, the mixed air enters the cylinder It is compressed; when the air intake hole is exposed, the combustible mixture flows into the crankcase.

The working principle includes two strokes: the first stroke: the piston moves up from the lower stop point. After the three pores are closed at the same time, the mixed gas entering the cylinder is compressed;When the intake hole is exposed, the combustible mixture flows into the crankcase.

The working principle of the two-stroke engine: The two-stroke engine is generally used in high-speed motorcycles. The first stroke of the piston from the lower stop point to the upper stop point closes the intake and exhaust valve and compresses the inhaled compressed gas.

How does the motorcycle engine work?

The following are the working principles of the two engines: the working principle of the two-stroke engine: the crankshaft rotates a circle and the piston goes back and forth in the cylinder to complete the intake (sweeping), compression, combustion and expansion, and exhaust. An engine with a working cycle is called a two-stroke engine.

The basic principle of motorcycle work is that the engine continuously generates heat energy, and the heat is connected through the crankshaft connecting rod.After it can be turned into a rotating force, the rear wheel is rotated by the variable-speed transmission device. When the ground friction force is overcome, it can drive the motorcycle.

The working principle of the four-stroke engine. The four-stroke engine has a wide range of uses. The four-stroke engine means that the piston ignites the cylinder every four reciprocing movements. The specific working principle is as follows: Air intake: At this time, the intake valve is opened, the piston is down, and the mixture of gasoline and air is sucked into the cylinder.

What is the working principle of the motorcycle engine?

The basic principle of motorcycle work is that the engine constantly generates heat energy. After the heat energy is converted into rotational force through the crankshaft connecting rod, the rear wheels are rotated by the variable-speed transmission device. When the ground friction is overcome, the motorcycle can be driven.

The following are the working principles of the two engines: the working principle of the two-stroke engine: the crankshaft rotates a circle and the piston goes back and forth in the cylinder to complete the intake (sweeping), compression, combustion and expansion, and exhaust. An engine with a working cycle is called a two-stroke engine.

Analysis: The working process of punching the engine is as follows: the piston moves upward and the mixed air flows into the crankcase. The piston moves down to press the mixed air to the combustion chamber to complete the first compression.

Motorcycle engines are generally gasoline air-cooled engines. In the past, gasoline and air were used to form a "combustible mixture" with a vaporizer, which was compressed into the cylinder and then ignited and burned at high pressure. Because the emission does not meet the standard, it has been replaced by the electric injection system in recent years. The so-called electric injection is an electronically controlled fuel injection system.

The motorcycle engine is a special gasoline engine, which combines the engine and the variable speed mechanism. It is roughly divided into two parts, the engine and the gearbox.

The crankshaft rotates at this time, and then the power is transmitted to the wheels through the gear change, and the car leaves. The single-cylinder engine [onlyThe piston of the engine with a cylinder] is pushed and returned by inertia. At this time, the gasoline burns again and circulates repeatedly. I'm not very professional, but you should understand the general principle.

How does the motorcycle engine work? And the role of transcending the clutch?

1. The basic principle of motorcycle work is: the engine constantly generates heat energy. After the heat energy is converted into rotational force by the crankshaft connecting rod, the rear wheels are driven by the variable speed transmission device with rotational force. When the ground friction force is overcome, the motorcycle can be driven.

2. Motorcycle engines are divided into two types, one is a two-stroke engine and the other is a four-stroke engine.

3. However, there may be only 2 small motorcycles.By meshing the gear with the gear lever, the gear shift fork can be moved in the transmission. X0dx0ax0dx0a clutch x0dx0ax0dx0a The work of the clutch is to connect and disconnect the power transmitted to the transmission of the engine crankshaft.

4. The transcendent clutch is actually a one-way clutch. Under the action of springs, rollers and bevels, it can only work in one direction, while the other direction is idle. When using electric start, the starting motor drives the crankshaft to rotate by surpassing the clutch to ignite the engine.

5. The transcendent clutch of a motorcycle is a one-way clutch. When this clutch rotates, it will join in one direction and idle in another direction. The electric start of the motorcycle uses this characteristic to realize the connection and separation of the starter motor and the engine.
