24v fuel level gauge
The different of 12v and 24v fuel level gauge: The difference between 12V and 24V electrical systems of cars: 12V voltage engines are usually engines with small compression ratio and small displacement. They can easily start the car with 12V starter. 24V power supply is applicable to large vehicles with high compression ratio and large displacement. Because large vehicles have high compression ratio and large friction coefficient of all parts, the starting force will be blocked, so the starter with high voltage and current should be used to start. Automobile electrical equipment mainly introduces the basic knowledge of automobile electrical system, battery, alternator and regulator, starter, automobile lighting, signal system and alarm device, automobile audio and video system, automobile electric auxiliary device, automobile electrical equipment circuit, etc.
1. Direct current
Because one of the power sources on the vehicle is the battery, which is a DC power source, and the battery must be charged with a DC power source after discharging. Therefore, the generator on the vehicle must also output DC power. Because of the above reasons, DC is used in cars.
2. Use low voltage power supply
The rated voltage of automobile electrical system is 12V and 24V. At present, gasoline vehicles generally use 12V power supply, and heavy-duty diesel vehicles mostly use 24V power supply.
3. Adopt single line system
Generally speaking, the connection between the electrical equipment and the power supply requires two wires, one is the live wire and the other is the zero wire, so as to form a circuit. However, all electrical equipment on the vehicle are in parallel and have good conductivity.
4. Negative grounding
Because the car adopts single-wire system, one of the two lines of the electrical system must be replaced by the metal body of the car. During wiring, one pole of the power supply and one end of the electrical equipment should be connected with the metal body. Such connection is called grounding.
How to set up 24v fuel level gauge
1. After the throttle knob is fully released, leave a certain free clearance, install the air filter, confirm the performance of other components, start the engine, let it warm up first, and open the choke first.
2. First, adjust it. First, screw the air adjusting screw to the end, reverse it for one turn, and then adjust the throttle screw to ensure that the engine can run at a certain speed after the throttle knob is completely relaxed.
3. First try to lower the idle speed to reduce the engine speed as much as possible.
4. Try to raise the idle speed and adjust the air adjusting screw again. The engine speed should be as high as possible.
5. Repeat the steps and adjust it several times to find a satisfactory idle speed
