How Often Should the Clutch Plate Be Replaced in an Automatic Transmission?

How many liters of gear oil should be added to the manual transmission of the Volkswagen New Jetta?

Volkswagen New Jetta manual transmission requires approximately three liters of gear oil. Introduction to automotive gear oil: It is a high-viscosity lubricating oil specifically designed to protect power transmission components, typically accompanied by a strong sulfur odor. Vehicle gear oil is classified based on performance and viscosity. Currently, the American Petroleum Institute (API) performance classification and U.S. military gear oil specifications are widely adopted worldwide. Most manual transmission lubricants and differentials use quasi-hypoid gear oils. These contain extreme pressure (EP) additives and anti-wear additives to handle the action of hypoid bevel gears. Working conditions of gear oil: During operation, gear oil experiences continuous changes in gear contact surfaces, with temperatures rising moderately, typically ranging from 10-80°C. Additionally, gear oil is subjected to extremely high pressure. During gear transmission, the unit pressure at the meshing part of the teeth can reach (196-245)×10 kPa, while hypoid gears can withstand unit pressures of (294-392)×10 kPa. Moreover, gear oil operates under conditions of significant speed variations and frequent rotations, making it prone to being squeezed out from the gaps between teeth, resulting in semi-fluid friction.

Where are the airbags located in the Geely Boyue Pro 2020 model?

In the Geely Boyue Pro, the driver's airbag is positioned at the center of the steering wheel. The front passenger frontal airbag is located within the dashboard on the passenger side. The front passenger seat side airbag is situated on the side of the seat back closest to the door. Airbag Composition: Primarily consists of airbag sensors, collision airbags, and electronic control units. The driver-side collision airbag is installed in the steering wheel; the passenger-side collision airbag is typically mounted on the dashboard. Airbag sensors are installed on the left, right, and center of the cabin partition; the central airbag sensor and airbag system are integrated with the electronic control unit. The airbag module mainly includes the airbag, gas generator, and igniter. The electronic control unit is used for data collection and processing, diagnosing the reliability of the airbag, ensuring timely ignition signal transmission when preset values are reached, and ensuring precise ignition timing to guarantee sufficient driving current for the gas generator. Function of Airbags: The primary role of airbags is to prevent injuries caused by collisions between passengers and interior components during a car crash, typically serving as a supplementary safety device to seat belts, with both working in tandem. The airbag system is a passive safety (see automotive safety performance) protection system that, when used in conjunction with seat belts, provides effective collision protection for passengers. In the event of a car collision, airbags can reduce head injury rates by 25% and facial injury rates by approximately 80%.

Why does the X-Trail's air conditioner only blow air without cooling?

Here are the reasons and solutions for the X-Trail's air conditioner only blowing air without cooling: 1. Incorrect mode Solution: If your fan starts but the main unit doesn't cool, check if your remote is set to cooling mode. Simply adjust it to cooling mode. 2. Insufficient refrigerant Solution: If both fan and main unit start, check if the refrigerant is adequate. If not, recharge it. However, before recharging, check for refrigerant leaks and fix any found. 3. Compressor failure Solution: Check if your compressor is functioning. If not, seek professional assistance.

What are the main components of an electronic control unit?

An electronic control unit is mainly composed of an input circuit, analog-to-digital converter, microcomputer, and output circuit. The functions of the electronic control unit include: fault self-diagnosis and protection functions. When a system failure occurs, it can automatically record the fault code in RAM and take protective measures to read substitute programs from the aforementioned inherent programs to maintain engine operation. The electronic control unit continuously monitors various input data and the operating states of the vehicle, calculates the information sent by various sensors according to pre-designed programs, and after processing, sends the parameters to the relevant actuators to perform various predetermined control functions.

What are the reasons for poor air conditioning cooling effect in Audi Q5?

It could be due to insufficient cooling capacity of the air conditioning system, poor heat dissipation leading to inadequate cooling, or poor sealing inside the vehicle. Below is relevant information: 1. Fault diagnosis and troubleshooting: Hot air entering through gaps in air ducts, repair sealing strips. Poor operation of control dampers in the heating assembly, improper adjustment of control cables, repair linkage rods or replace the heating assembly. 2. Working principle: The automotive air conditioning refrigeration system consists of compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. These components are connected by copper pipes (or aluminum pipes) and high-pressure rubber hoses to form a sealed system. During operation, the refrigerant circulates through this sealed system in different states, with each cycle consisting of four basic processes.
