Is Transmission Fluid Basically Unnecessary to Replace?

What is the reason for oil leakage from the vent hole on the transmission?

After driving, the internal gears of the transmission heat up, causing the transmission oil to also heat up, which results in the expansion of the transmission volume. Below is an introduction to the transmission: 1. Main functions: Changing the transmission ratio to expand the range of torque and speed variations of the drive wheels, adapting to frequently changing driving conditions, while allowing the engine to operate under favorable conditions. It enables the car to reverse while keeping the engine's rotation direction unchanged. By using neutral gear, it interrupts power transmission, allowing the engine to start, shift gears, and facilitating gear changes or power output. 2. Working principle: A manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.

What are the symptoms of a faulty car fuel pump?

Here are the symptoms of a faulty car fuel pump: 1. Performance: Weak acceleration, jerking when suddenly accelerating; Difficulty starting, requiring prolonged cranking; Engine warning light illuminated; Abnormal noises during driving; Abnormal engine vibration; Fuel supply system failure. 2. Causes of fuel pump damage: Use of low-quality gasoline leading to excessive impurities, causing clogging of the pump's suction filter; Failure to regularly replace the fuel filter that traps impurities; Delayed refueling, accelerating fuel pump damage. The function of the fuel pump is to pressurize the oil from the oil pan and deliver it to the oil filter and various lubrication channels, lubricating the engine's main moving components and filtering the oil.

What are the effects of excessive urea concentration in vehicle exhaust treatment?

Excessive urea concentration in vehicle exhaust treatment can affect the reduction of automotive emissions, leading to ammonia slip and the formation of secondary pollutants. Below is relevant information about urea: 1. Concept: The SCR solution has significant advantages in the National IV diesel vehicle emission treatment system, and vehicle urea is an essential additive for the SCR solution. 2. Operation process: The operation process of the SCR system is as follows: when nitrogen oxides are detected in the exhaust pipe, the urea tank automatically sprays diesel exhaust fluid. The diesel exhaust fluid and nitrogen oxides undergo a redox reaction in the SCR catalytic reaction tank, producing non-polluting nitrogen and water vapor, which are then discharged.

What are the reasons for the restricted power output of the Little Ant?

The following are the reasons for the restricted power output of the Little Ant: 1. Battery temperature control system: If the power battery is too hot or too cold, it will limit the power output. This is a protective measure and acceptable in extreme weather conditions, which is a drawback of not having a battery temperature control system. 2. Battery cells: If the voltage difference between the power battery cells exceeds 200mv, a small turtle icon will appear, which is also a protective measure. The best solution is to go to a 4S shop to apply for replacing the low-voltage or high-voltage cells. 3. Battery consistency: The appearance of the small turtle icon is not unique to the 726 model; it is clearly due to poor battery consistency, indicating that the grouping and capacity determination step was not done properly.

What is the Leading Enterprise of Permanent Magnet Motors for New Energy Vehicles?

Here is an introduction to the leading enterprises of permanent magnet motors for new energy vehicles: 1. Introduction: Permanent magnet synchronous motors use permanent magnets to provide excitation, making the motor structure relatively simple, reducing processing and assembly costs, and eliminating the problematic slip rings and brushes, thereby improving the operational reliability of the motor. Additionally, since no excitation current is required, there is no excitation loss, which enhances the motor's efficiency and power density. 2. Composition: Permanent magnet synchronous motors consist of components such as the stator, rotor, and end covers. The stator is basically the same as that of a conventional induction motor, using a laminated structure to reduce iron losses during operation. The rotor can be solid or made of laminated sheets. The armature winding can be a concentrated full-pitch winding or a distributed short-pitch winding and unconventional winding.

What Causes Fluctuating Idle Speed When the Car AC is On?

Here are the reasons for fluctuating idle speed when the car AC is on: 1. Engine control logic error: When unable to determine whether the AC is on, the engine control unit (ECU) may mistakenly interpret it as a temporary high load, attempting to compensate by increasing RPM to offset idle resistance. When engine speed drops, it cannot handle the AC compressor load, causing RPM to rise again. This back-and-forth results in unstable idle. 2. AC control circuit error: Similarly to the first point, because the system cannot determine AC activation status, the ECU continuously adjusts idle speed, manifesting as unstable idle. 3. AC circuit malfunction: When the AC is off, the compressor belt runs without load, thus not affecting engine load. The AC compressor's intermittent operation forces continuous idle speed adjustments, showing as unstable idle.
