electric tachometer for diesel engines

The engine speed is related to the number of work done per unit time or the effective power of the engine, that is, the effective power of the engine changes with the speed. Therefore, when describing the effective power of the engine, the corresponding speed must be indicated at the same time.

The effective power and its corresponding speed specified on the engine product label are respectively called the rated power and rated speed. The working condition of the engine at the rated power and rated speed is called the calibrated operating condition. The rated power is not the maximum power that the engine can produce. It is the maximum use limit of the effective power developed according to the purpose of the engine.

When the engine of the same model is used for different purposes, its rated power value is not the same. The effective torque also varies with engine operating conditions. Therefore, the maximum output torque and the corresponding vertical speed of the automobile engine are used as an index to evaluate the dynamic performance of the engine.

The electric tachometer 2200-2500 is normal. Every car has a megatachometer, so the speed of the car can be controlled by itself. During driving, the engine speed of the car is about 2200-2500. No matter in which gear, keep the number of revolutions of the starting limb divination machine at about 2200-2500. The car can't move at too low speed, the fuel consumption is not in the corridor, and the engine is injured; Too high speed increases invalid fuel consumption and damages the diesel engine.

It is normal for the car engine to rotate from idle speed to four or five thousand parallel speed. However, do not slip the pin to rotate at low speed and high speed so that the chain will not damage the engine. In addition to the top gear, you can change to a higher gear when you are not driving more than twothousand revolutions.

Observe the rotating speed of the engine crankshaft per minute and the problems of the chalula motor of Sibo automobile. It can be seen from the engine speed that the engine condition, the sliding quality of the engine and the current operation of the engine can be judged.Usually, the speed is used. If the grinding speed is too fast, the tachometer will change more obviously. If the tachometer doesn't move all the time, it is said that there is a problem with the engine of the blind and Jueming cars.
