mechanical tachometer for diesel engine

• 2022-04-08

What's the use of diesel engine mechanical tachometer? Many people have their own views on this, but they are all one-sided. The mechanical tachometer is generally set in the instrument panel and placed symmetrically with the speedometer. So what's the use of engine tachometer? The following compendium will give you a brief introduction:

The engine tachometer works according to the magnetic principle. It receives the pulse signal generated when the primary current in the ignition coil is interrupted and converts this signal into a speed value that can be displayed. The faster the engine speed, the more pulses generated by the ignition coil, and the greater the speed value displayed on the table.

It can intuitively display the speed of the engine under various working conditions. The driver can know the operation of the engine at any time, cooperate with the transmission gear and throttle position, and keep it in the best working state, which is good for reducing fuel consumption and prolonging the service life of the engine. The engine tachometer can help prolong the service life of the engine and give full play to the power of the engine accurately. The engine tachometer is used to monitor the engine operation at any time. It can provide the driver with the engine load and provide great maintenance help for the maintenance personnel. You can see the speed and load of the engine, and whether it is speeding at high speed. When driving, you can judge whether the engine works normally by looking at the engine speed. The tachometer intuitively displays the current speed of the engine. If the pointer shakes under the idle state, it indicates that the idle speed of the engine is unstable and needs to be repaired in time. In the driving state, the driver can select the shift time according to the speed, and use the output characteristics of the engine at different speeds to drive in the state of power and fuel consumption.

The tachometer is used to detect the revolutions per minute when the diesel generator set is running. The tachometer has two types: mechanical drive and electric drive. The joint of the flexible shaft of the mechanically driven tachometer is directly connected with the transmission shaft at the rear end of the governor. The electric tachometer is composed of tachometer indicator and sensor, and the sensor is connected with the tachometer by wire.
