combination analog speedometer tachometer mph
The speed is the speed at which the engine crankshaft runs. The speed is the speed at which your car runs. The two are isolated and related. The high speed also lies in the gear of the gearbox. In the same gear (except neutral), the higher the engine speed is, the faster the car moves. On the contrary, it is also established that 4 revolutions is the speed of the engine crankshaft per unit time, and 10 horses is the distance the car moves per unit time.
Our company's two in one combination analog speedometer tachometer mph , also include the instantaneous mileage and total mileage, as well as direction lights. The speed, engine tachometer and throttle are integrated. The higher the throttle is, the higher the speed is, the more power will be added In domestic cars, tachometers were generally not set in the past, but in recent ten years, tachometers have been installed in various types of cars, and some manufacturers also take them as the configuration content of car grade. The tachometer unit is 1 / min1000, which shows how many kilorevolutions the engine rotates per minute. The tachometer 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 to keep it in the best working state, which is good for reducing fuel consumption and prolonging the service life of the engine.
Tacho : the speed of the engine 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 called rated power and rated speed respectively. The working condition of the engine at the rated power and rated speed is called the rated working condition. The rated power is not the maximum power that the engine can emit, but the maximum use limit of effective power according to the purpose of the engine. When the engine of the same model is used for different purposes, its rated power value is different. The effective torque also varies with engine operating conditions. Therefore, the maximum torque and its corresponding speed that the automobile engine can output are used as an index to evaluate the power performance of the engine.
Speed : that is, the distance traveled by the vehicle at its current speed for one hour. An automobile is a vehicle that can be driven by its own power and can be driven without being erected according to track or electricity. Broadly speaking, a vehicle driven by its own mechanical energy is generally called a car.
