Engine tachymeter: how to read and Solar panel imports HS code referencesuse? Engine tacometer, also known as tacometer, tacometer, engine tacometer, etc., is an instrument used to measure engine speed.It is widely used in various means of transportation such as automobiles, airplanes and ships, so that the driver can grasp the speed of the engine in time, so as to better control the performance of the car or aircraft. So, how to read and use the engine tachymeter? The following will be analyzed in detail from the following aspects. I. Read the engine tachometer. The engine tachmometer is usually divided into two types: mechanical tachometer and electronic tachometer. The following is an explanation of these two types of reading methods respectively. 1. Mechanical tachometer Mechanical tachmometer is mainly composed of a mechanical transmission mechanism and a pointer. When the engine speed gradually increases, the spring in the mechanical transmission mechanism will be stretched, thus driving the pointer to move gradually and indicating the engine speed. Mechanical tachometers are usually divided into two types: direct and indirect. The direct tacmometer is directly connected to the engine, and the engine speed will be displayed on the dial of the tacmometer.The indirect tacmometer is usually connected to the ignition system of the car, in which a cable is connected to the ignition coil. The cable will drive the clutch through the tachometer, and then transmit the engine speed to the pointer of the tachometer. Two. Electronic tachometer Electronic tachometer is usually composed of a measurement circuit and a digital display. Measure the standardized voltage of the circuit and then transmit it to the generator. The generator creates an electric field on the rotor driven by the engine and transmits electrical signals through the measurement circuit. The digital speed displayed by the electronic tachometer is usually displayed on the screen. Unlike mechanical tachometers, electronic tachometers usually require the installation of a power supply, which can be easily installed without environmental interference, and can provide more accurate measurements in digital form. II. To use the engine tachymeter, you need to follow the following steps: 1.Determine the maximum speed of the vehicle. The maximum speed of each car is different. The maximum speed of some cars may be above 7000rpm, while others may be below 5000rpm. For higher-performance vehicles, the maximum speed will be higher. Therefore, before preparing to use the tacmometer, you must determine the maximum speed of your car and calculate the target speed accordingly. Two. Connect the tacmometer to the car circuit or directly to the engine depending on the type of tactometer. 3. Set the target speed to the value to be displayed by the tachymeter pointer and set the tachymeter to the target speed. This means that you must manually rotate the dial according to your target speed until the pointer points to the speed you want to achieve. If you have an electronic tactometer, you just need to set the number on the instrument.Four. Start measuring the engine speed, start the engine, and observe the pointer or digital display of the tacometer. If you need to change the engine speed, you can refuel or step on the brake. If you find yourself approaching the maximum speed, you should slow down the throttle as soon as possible and stop accelerating. In a word, the use of engine tachimeter is very simple, but very important. By understanding your car and target speed, you can use a tachymeter to ensure that you are always driving at a safe speed. This can extend the life of the engine and improve the safety of driving.
