Wuyang Honda scooter stepless speed regulation principle

Stepless speed regulation principle: composed of two groups of gears or pulleys that can change the diameter, connected by chains or belts, by changing the teeth The diameter of the wheel or pulley is used to control the variable speed ratio. For constant torque load, the constant torque speed regulation method should be adopted.

Before accelerating, put on the correct gear: first choose the appropriate gear according to the speed and road conditions. Don't step on the accelerator as soon as you get up, otherwise it is easy to cause the body to shake out of control. Accelerate quickly after riding at a steady speed: After driving at a constant speed for a period of time, accelerate by increasing the accelerator appropriately.

The stepless transmission on the scooter uses this principle: when the diameter of the belt changes on the front active wheel and the rear active wheel, the speed and torque change accordingly.

The carburetor acceleration pump (speed-up pump) of Wuyang Honda 125-A is actually an auxiliary fuel injection device.

Improper adjustment of the carburetor: The adjustment ratio of the carburetor is too small, which will cause the fuel mixture to be too thin, and the energy generated by combustion will not provide kinetic energy for the motorcycle. The owner can increase the proportion of gasoline in the mixed gas by turning the carburetor nut, and then observe the color of the electrode in the center of the spark plug to adjust to the appropriate mixing ratio.

Good. The Nanya 125 pedal motorcycle is equipped with a PGMFI electric injection system and a Wuyang Honda Shark TECH series engine. It has good fuel economy, stable working performance and low maintenance requirements.

Dynamic diagram of the working principle of automobile air conditioning compressor

1. The working principle of automobile air conditioning can be divided into four processes, namely compression, heat dissipation, throttling and heat absorption.

2. The compression process of the working principle of automobile air conditioner: the compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator and compresses it into high-temperature and high-pressure gas to discharge the compressor.

3. The working principle of the compression process of the automobile: the compressor inhales the low-temperature and low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature and high-pressure gas and discharges it into the compressor.

4. Working principle and process: The working process of the rotary slash compressor is shown in Figure 4-48. When the compressor shaft rotates, the slash on the shaft drives all pistons to move at the same time. Some pistons move to the left, and some pistons move to the right.

Tianli car owners are so happy: What is variable compression ratio technology and what is it used for?

The variable compression ratio can improve the thermal efficiency of the engine and reduce fuel consumption. After adopting the variable compression ratio technology, the engine can work under the conditions of explosion limitation, regardless of the working conditions, and obtain the best thermal efficiency.

Vary compression ratio means that the compression ratio of the engine can be changed, so that different compression ratios can be used under different working conditions, which can improve the efficiency and fuel economy of the engine. The new Nissan Tianyi 0t model is equipped with variable compression ratio technology. The compression ratio refers to the compression ratio of the combustion chamber. Generally, the compression ratio of naturally aspirated engines is relatively large.

The variable compression ratio is a technology to dynamically adjust the compression ratio of internal combustion engines. Variable compression ratio can improve fuel efficiency under different load conditions. A low compression ratio is required for high load, while a high compression ratio is required for low load.

And the VCT (i.e. variable compression ratio turbocharged engine), the compression ratio can be intelligently adjusted between 8:1-14:1. Compared with the high compression ratio model, it can be adjusted to 8:1 to provide lasting and strong power.Compared with the low compression ratio model, the intelligent adjustment is 14:1, which is more fuel-efficient and quieter.

Which boss has the dynamic diagram of the air intake system?

Intap bellows. The engine air intake system itself is sealed. In order to achieve this effect, an intake pipe is needed to convey clean air.

VVT—i. The system is the English abbreviation of Toyota's intelligent variable valve timing system. The engine of the latest Toyota sedan has been generally equipped with the VVT-i system. Toyota's VVT-i system can continuously adjust the valve timing, but cannot adjust the valve lift.

There is an intake valve and an exhaust valve at both ends of each cylinder. The piston is driven by a slash disk to reciprocate in the cylinder.When one side of the piston is compressed, the other side is the intake.
