Car fan not rotating at high speed may be caused by the following reasons: 1. The car fan itself is faulty; 2. The temperature controller or relay of the car fan is faulty. Below is relevant information about car electric fans: 1. Working principle: Generally divided into two-speed operation. When the car's air conditioning is turned on, it also controls the operation of the car's electric fan. When the engine needs cooling, it drives the car's electric fan to work. 2. Function: It can minimize the energy consumption of the car engine. The car's electric fan is generally installed behind the car's radiator, while some car models install the fan in front of the radiator. The radiator temperature is cooled by the fan to ensure the use of the car engine.

What Causes Gear Shifting Jerk in Cars?

Automatic transmission shifting jerkiness may be caused by: transmission clutch pressure leakage; transmission oil circuit blockage or poor flow; transmission fluid not filled to standard; or solenoid valve damage. The engine's power is transmitted through the transmission, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, more gears mean better fuel efficiency. Below is relevant information: 1. Solenoid valve damage: If sludge in the transmission fluid circulates and blocks the oil passages in the valve body, it can cause shifting jerkiness. Over time, this can lead to transmission overheating, impact, slippage, and other transmission issues. 2. Transmission fluid not filled to standard: Check whether the transmission fluid is filled to the correct level. Both insufficient and excessive transmission fluid can cause this issue. Vehicles with a transmission dipstick can check the fluid level against the standard markings when the engine is running.

Why is water dripping from the exhaust pipe of the Huansu S5?

Water dripping from the exhaust pipe of the Huansu S5 is a normal phenomenon. After gasoline undergoes complete combustion, it produces carbon dioxide and water vapor. When the water vapor condenses, it forms liquid water, which is discharged through the exhaust pipe once it accumulates to a certain amount. In fact, water dripping from the exhaust pipe is a good sign, as it indicates that at least three conditions are met: 1. The air-fuel mixture ratio is correct: This indicates that the fuel supply system is in good condition. 2. The engine's cylinder pressure is normal: This means there is no internal wear in the engine block, and components such as cylinder liners and sealing rings are functioning properly. 3. The exhaust pipe temperature is low: This shows that the heat generated during combustion is concentrated within the cylinders, with only a small amount escaping into the exhaust pipe, indicating strong engine power output.
