Pressure lubrication refers to adding an oil pump to the engine, which uses the pressure of the oil pump to forcibly supply oil to various components. More related information is as follows: 1. Pressure lubrication is a type of forced lubrication, mainly relying on the pressure generated by the oil pump to deliver lubricating oil. It is primarily used for lubricating heavily loaded friction surfaces such as main bearings, connecting rod bearings, and camshaft bearings. 2. The function of pressure lubrication is to alter product performance. Improved lubrication can reduce the temperature between components, which helps enhance the toughness of the product. Currently, there are three types of lubrication systems used in automobiles: pressure lubrication, splash lubrication, and composite lubrication.

Pressure lubrication is a critical system in automotive engines, where the oil pump pressurizes and forcibly delivers oil to moving components like crankshaft bearings and camshafts, reducing friction and wear. Unlike splash lubrication that relies solely on parts flinging oil, pressure lubrication ensures uniform oil coverage across all components, maintaining effective lubrication during high-speed operation or heavy loads. From my experience, if oil pressure drops, the dashboard warning light will illuminate—promptly pull over for inspection rather than continuing to drive, as engine seizure could occur. For routine maintenance, using high-quality oil and regularly replacing the oil filter prevents oil passage blockages or pump failures, extending engine life by at least five years.

Having driven for decades, I believe pressure lubrication is the lifeline of modern engines. The oil is pressurized by the pump and delivered to every corner, far more reliable than the old splash lubrication, especially during uphill climbs or long-distance driving, as it maintains temperature balance. For maintenance, I frequently check the dipstick to ensure the oil level is appropriate; if the oil pressure warning light comes on, it's time to replace the oil and filter. Don't overlook the small details—failure of pressure lubrication can lead to excessive wear and ultimately engine failure. I learned this the hard way when I was younger, and now regular maintenance keeps my car running smoothly.

What to Do If the Car Exceeds the First Maintenance Period?

The solution for a car exceeding the first maintenance period is: if it's overdue by about a month, the first maintenance can generally still be performed. The 4S dealership and manufacturer usually have a grace period for overdue first maintenance in terms of both time and mileage. The first maintenance is determined by two indicators: mileage and time, whichever comes first. It's not necessary to meet both conditions; exceeding either one can affect the first maintenance. The purposes of the first maintenance are: 1. To ensure the vehicle is in good performance condition; 2. To effectively improve the vehicle's efficiency and reduce wear on parts and tires; 3. To enhance driving safety; 4. To prevent vehicle malfunctions; 5. To reduce noise and environmental pollution; 6. To maintain the vehicle's appearance and prevent damage.

How to Turn on the Rear Air Conditioning in a Passat?

The method to turn on the rear air conditioning in a Passat is: Press the second button inside the middle knob of the central air conditioning control area. If the indicator light is on, the rear air conditioning is off; if it is not lit, the rear air conditioning is on. The independent rear air conditioning means that the rear seats can set a different temperature from the front seats and adjust the airflow volume. The Passat is a mid-size sedan under SAIC Volkswagen, with a length, width, and height of 4933mm, 1836mm, and 1469mm respectively, and a wheelbase of 2871mm.

How Thick Are Brake Pads?

Brake pads are approximately 1.5cm thick. As they wear down from friction during use, their thickness gradually decreases. Each brake pad has a raised indicator on both sides, which is about 2-3mm thick—this is the replacement limit for brake discs. The working principle of brake pads is to convert the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and brake drum, as well as between the tires and the ground, thereby bringing the vehicle to a stop. Brake maintenance methods include: 1. High-temperature protection to prevent corrosion of the braking system and avoid brake pads seizing due to overheating; 2. Clean oil stains from brake discs and drum components to ensure proper heat dissipation; 3. Replace brake fluid regularly; 4. Periodically check the thickness of brake pads or brake shoes.
