What is the Voltage of a Car Generator?

The normal voltage range of a car generator after starting the engine is "15.3V-12.8V"; below is relevant information about car generator voltage:1. Normal generator voltage conditions: When the vehicle's air conditioning is operating and other electrical devices are used excessively, the generator voltage may drop below 12.8V. At this point, the vehicle draws current from the battery and cannot charge the battery. After starting, the battery voltage is essentially equal to the generator voltage, minus the voltage drop due to line loss from the generator to the battery. When the engine is not running, the normal battery voltage range is 13.8V-12.8V. 2. Introduction to the generator: The car generator is the main power source of the vehicle. Its function is to supply power to all electrical devices (except the starter) while the engine is running normally (above idle speed) and simultaneously charge the battery. Based on the three-phase stator winding of a standard alternator, additional winding turns are added with lead-out terminals, and an additional three-phase bridge rectifier is included. At low speeds, the output is from the series connection of the original and additional windings, while at higher speeds, only the original three-phase winding provides the output.

What was the brand of China's first domestically produced automobile in July 1957?

In July 1957, China's first domestically produced automobile was the Jiefang brand truck. Here are the relevant details: 1. Origin of the name: In the second half of 1953, the Stalin Automobile Plant suggested to the Chinese side to name the new tonnage truck. After consultation with Chairman Mao Zedong through his close associates, the Chairman personally decided on the name "Jiefang" (meaning "Liberation"). 2. Prototype: In July 1956, China's first domestically produced Jiefang CA10 tonnage truck rolled off the production line. At that time, FAW Group received assistance from the Soviet Union in automobile construction, and the chosen model was the ZIS-type tonnage truck from the Stalin Automobile Plant, which became the prototype for the Jiefang brand truck.

Why does the Outlander air conditioning compressor start frequently?

The frequent starting of the Outlander air conditioning compressor can be attributed to several reasons, with the most likely cause being the tripping of the compressor protection device. A tripped compressor overload protection indicates that the system voltage is too high or the overheat current is excessive. Another possible cause is the burnout of the starting capacitor or the compressor starting coil. The reasons for excessive voltage, high pressure, or overheating and their corresponding solutions are as follows: 1. Excessive refrigerant: Appropriately reduce the refrigerant amount. 2. Poor heat dissipation: Check the condenser pipes for dirt and clean the condenser. 3. Blockage in the pipeline system: Refer to the pressure gauge for judgment and troubleshooting, then reprocess the system. 4. Dust and scale accumulation on the evaporator or filter, leading to reduced airflow and imbalance in system pressure and temperature: Clean the evaporator or filter. 5. Lack of refrigerant (Freon): Add an appropriate amount of Freon.

Why is there a strange noise when braking while reversing?

The reason for the strange noise when braking while reversing is due to the moving caliper hitting the caliper bracket during the reverse process. Below are the relevant explanations: 1. Radar system: When the car moves from the warning zone into the danger zone, the radar system automatically activates the braking device to control the car's reverse movement. The principle is based on an ordinary reverse radar system, with the addition of a servo mechanism that has a braking function. When the car moves from the warning zone into the danger zone, the controller sends a control signal to the braking servo, which immediately activates to automatically stop the car from moving backward, ensuring safe reversing. 2. Braking: When driving forward and braking, there is no 'play gap' at the lower connection point with the brake bracket, so no noise occurs. However, when braking in reverse, the brake caliper moves upward and hits the upper bracket, producing the strange noise.

Which is better, supercharger or turbocharger?

Both supercharging methods have their own advantages and disadvantages. The following are the differences between a supercharger and a turbocharger: 1. Power: A supercharger uses the engine's own power to drive a compressor for boosting. 2. Consumption: The supercharger consumes the engine's power, and its speed changes with the engine speed, avoiding boost lag. It performs exceptionally well at low engine speeds but is limited by the engine speed, resulting in insufficient boost at high engine speeds. 3. Exhaust: A turbocharger utilizes the exhaust gases produced by the engine to drive a turbine in the exhaust pipe, which in turn drives a turbine in the intake pipe for indirect boosting, without consuming the engine's power. 4. Speed: The turbocharger operates at extremely high speeds, providing several times higher boost pressure than a supercharger. However, due to the inertia of the turbine and the significant resistance of the intermediate bearings, the turbine speed does not increase simultaneously when exhaust gases suddenly increase, which is known as turbo lag.

Why Has the Car Horn Sound Become Quieter?

Car horn sound may become quieter due to reasons such as excessive battery discharge, contact point erosion or poor contact, as well as loose or poor contact at terminal connections. Below is a detailed introduction to car horns: 1. Introduction: The horn is the audio signaling device of a car. During driving, the driver can emit necessary audio signals as needed and required to warn pedestrians and alert other vehicles, ensuring traffic safety, while also being used for urging and signal transmission. 2. Working Principle: The car electric horn produces sound through the vibration of a metal diaphragm. The car electric horn consists of an iron core, magnetic coil, contacts, armature, diaphragm, etc. When the driver presses the horn switch, current flows through the contacts to the coil, generating magnetic force that pulls down the armature, forcing the diaphragm to move. The movement of the armature causes the contacts to open, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, along with the armature, returns to its original position under its own elasticity and the spring plate's action, closing the contacts again to reconnect the circuit. Current then flows through the contacts to the coil, generating magnetic force and repeating the above actions. This cycle repeats continuously, causing the diaphragm to vibrate repeatedly and thus producing sound.
