What is the charging voltage of a 12-volt battery?

12-volt battery charging voltage is between 12.8 volts and 13.0 volts. The voltage of a 12-volt battery is not fixed; the greater the charge, the higher the voltage. The voltage generated by a car's alternator is typically higher than that of the battery. Additionally, the alternator's voltage is related to the engine's speed—the higher the speed, the higher the voltage. Therefore, the battery's voltage is not constant. The car battery is a crucial component of the vehicle, providing power to the starter motor. It supplies electricity to the engine ignition system and other electrical devices when the engine is starting or running at low speeds. When the engine operates at high speeds, the alternator generates sufficient power, and the onboard charger automatically stores excess electricity in the car battery.

What are the disadvantages of a CNG ignition advancer?

CNG ignition advancer has the following disadvantages: 1. It may shorten the service life of the engine; 2. It can make the car slower when starting and more prone to stalling. Precautions when installing a CNG ignition advancer include: 1. Before installation, ensure that the wiring harness setup of the ignition advancer matches the vehicle model to be modified; 2. During installation, keep it away from wet and high-temperature areas; 3. Keep it away from high-voltage ignition wires and maintain good insulation. The ignition advancer can automatically adjust the ignition timing, ensuring the engine operates at the optimal ignition timing under different speeds. It accommodates both fuel and gas conditions without altering the original engine compression ratio or combustion structure. Based on the position of the conversion switch, it achieves precise control of different ignition timings for dual-fuel vehicles through microcontroller control.

What is the Principle of a Universal Joint?

The principle of a universal joint is: The structure and function of a universal joint resemble the joints in human limbs, allowing the angle between connected parts to vary within a certain range. To meet the requirements of power transmission and accommodate the angle changes caused by steering and the up-and-down movement of the car during operation, the drive axle of front-wheel-drive vehicles often uses universal joints to connect the half-shaft and the wheel axle. A single universal joint cannot ensure that the instantaneous angular velocity of the output shaft matches that of the input shaft, which can easily cause vibration, accelerate component wear, and generate significant noise. Various types of constant-velocity universal joints are widely used in front-wheel-drive vehicles, with two constant-velocity universal joints per half-shaft. The universal joint closer to the transaxle is the inner half-shaft universal joint, while the one near the wheel axle is the outer half-shaft universal joint.
