What does motorcycle tachometer mean?
The tachometer unit is 1/min×1000, that is, it shows how many thousand revolutions the engine makes per minute. The tachometer can intuitively display the speed of the engine under various working conditions. The driver can know the running situation of the engine at any time, and cooperate with the gear position of the transmission and the throttle position to keep it in the best working condition, which is helpful for reducing fuel consumption and prolonging the life of the engine benefit. What does motorcycle speed mean. There is a relationship, the corresponding speed and gear are almost the same. The motorcycle starts in the first gear. At this time, the engine speed is about 2000-3000 rpm, and the second gear can be shifted. The gear corresponds to the speed. The engine speed is high. If you put it in a low gear, it will cause the vehicle to run away. If the speed is low, put it in a high gear. bit, causing the vehicle to stall and reverse. Riding a motorcycle requires skill and experience, and the coordination of hands and feet.
Motorcycle engine tachometer: A motorcycle is an ordinary means of transportation, and its power comes from the engine. Like a car, it can only be driven with the gas pedal, and it also has an engine tachometer and a speedometer. Then when the engine tachometer is at 4500 rpm, how much will it run? This depends on how many gears it is in. In the first and second gears, it is only twenty or thirty yards, in the third and fourth gears, forty to fifty, five It will reach more than sixty or seventy yards when it is in gear. The speed corresponding to the motorcycle tachometer is about 12 kilometers per hour. Generally, there are only two or three people on the motorcycle dashboard. The representatives are the speedometer, one is the tachometer, and the other is the fuel gauge. Three throttle gauges. The speedometer of a motorcycle is basically the same as the reading of the tachometer, that is, if the tachometer of the motorcycle is 1200 rpm, the speedometer will display about 12 kilometers, which is not much different. Working principle of motorcycle tachometer.The idle speed of the motorcycle engine is 1400 (plus or minus 100) rpm. Most domestic motorcycles have a maximum revolution of 7000 to 9000. Individual domestic motorcycles can reach 11,000 rpm.
How a tachometer works: Electronic tachometers are based on the principle of electromagnetism. The iron is connected to the pointer, and the solenoid wire set is wound outside. The electromagnet has three wires, which are positive pole, negative pole and high voltage covered wire. That is the ignition wire of the engine. Every time this line goes out, the motor will fire once, which means two revolutions. According to this principle, the electromagnet is magnetized once every time it is passed. The faster you turn, the stronger the magnetic force, and the pointer will go up.
