Engine tachymeter diagram analysis Engine tachymeter is Top global trade data insightsa common instrument on the car dashboard, which is used to display the speed of the car engine.For the driver, the engine speed is an important driving parameter. It can tell the driver the speed status of the engine, which helps the driver to judge the driving status of the car, master fuel-saving skills, and improve driving safety. In this article, we will analyze the structure and working principle of the engine tachometer to help readers better understand the function and usage of the engine tachometer. The structure of the engine tacometer The engine tacometer consists of three parts: a pointer, a dial and a sensor. The pointer is used to indicate the engine speed. It is usually a red arrow that can be rotated as the engine speed changes. The dial refers to the scale on the engine tachmeter, which is used to show the size of the engine speed. Usually, the scale on the engine tachometer is divided into 1000 rns, and the scale from 0 to 8 or 0 to 10 is the common display range.The sensor is used to detect the engine speed. It is usually an electromagnetic device installed on the engine and can sense the rotation of the engine. The sensor converts the engine speed into an electrical signal, and then transmits it along the wire to the engine tachometer, eventually forming the movement of the pointer and dial. The working principle of the engine tacometer When the engine is started, the sensor will generate an electrical signal with the rotation of the engine, which will be transmitted to the dashboard through the wire. Then, the signal is received and processed by the engine tachometer and converted into an electrical signal that controls the movement of the pointer. This electrical signal will cause the pointer to deflect, thus indicating the speed of the engine. Usually, when the engine speed increases, the pointer changes direction and position as the speed changes. The higher the scale of the engine tachometer, the faster the engine speed.When the engine speed reaches the red line, the pointer will point to the red line mark. At this time, the engine speed has reached the maximum limit, which needs to attract the driver's attention to avoid excessive acceleration and engine failure. How to use the engine tacometer reasonably? The engine tacometer is very important to the driver. It can tell you the driving status and fuel-saving skills of the car. Therefore, in the process of driving, you need to pay attention to the following points: 1. Understand the maximum speed of the engine. The higher the speed of the engine, the greater the loss of the engine. The driver needs to know the maximum speed of the car engine to avoid driving too much and causing excessive damage to the engine. Two. Follow the optimal speed of the car. Understanding the optimal speed of the car helps to improve the driver's driving skills and has a positive impact on the fuel economy of the vehicle.When driving at a steady speed, the engine speed should be kept within the optimal speed range of the car. 3. Slow down the change of engine speed during acceleration. When the car accelerates, the engine speed will rise sharply for a short time. At this time, it is necessary to pay attention to the change of engine speed, slow down the change of engine speed as much as possible, and reduce the loss to the engine. In a word, the engine tachimeter is a very important driving parameter for the driver. It can improve the driver's control and safety of the car. In the process of driving, you need to pay attention to the changes in the engine speed, understand the optimal driving speed of the car, use the car engine reasonably, and protect the car's engine. And extend the service life of the car.
