Lubrication system has the following five major functions: 1. Lubrication: Engine oil forms an oil film between moving parts, reducing friction resistance and power loss, and minimizing component wear. 2. Cooling: Utilizing the fluidity of engine oil to carry away part of the heat from engine components, preventing excessive temperatures and burning damage. 3. Cleaning: Circulating engine oil carries away metal particles generated during engine operation, dust inhaled from the atmosphere, and some solid substances produced by fuel combustion, preventing the formation of abrasives between parts and reducing wear. 4. Sealing: The viscosity of engine oil allows it to adhere to the surfaces of moving parts, improving sealing effectiveness and reducing gas leakage. 5. Rust prevention: The lubricating oil film adheres to metal surfaces, isolating air and water, providing rust and corrosion protection.

What is the valve clearance for Weichai engines?

Weichai intake valve clearance is 0.3mm, and exhaust valve clearance is 0.35mm. There are two common methods for checking and adjusting valve clearance: 1. Cylinder-by-cylinder adjustment method - After determining the piston position at compression top dead center according to the cylinder firing order, the intake and exhaust valve clearances of that cylinder can be adjusted; After adjustment, rotate the crankshaft and gradually adjust the valve clearances of other cylinders using this method. 2. Two-step adjustment method - Rotate the crankshaft to position the first cylinder piston at compression top dead center, align the flywheel mark with the inspection hole mark, then adjust valves 1, 2, 4, 5, 8, and 9. Then rotate the crankshaft one full turn to position the sixth cylinder piston at compression top dead center, and adjust valves 3, 6, 7, 10, 11, and 12.

Is it dangerous not to change transmission oil?

Not changing transmission oil is extremely dangerous. Failure to change the oil can lead to the following problems: 1. Reduced transmission efficiency, making the vehicle consume more fuel and causing delayed power response. 2. Gear shifting becomes less smooth, with noticeable lag. 3. Unstable RPM during gear changes, increasing the burden on the powertrain. 4. Accumulated impurities and deposits inside the engine may clog oil passages, reduce cooling efficiency, and increase the risk of vehicle failure. 5. Changes in the PH value inside the transmission, accelerating component wear and shortening service life. Below are the methods for changing transmission oil: Transmission oil replacement can be done manually or by machine. Manual replacement is similar to changing engine oil, relying on gravity to drain the old oil, but this method only removes about 30% of the old oil, with significant residue remaining in the oil pan, requiring its removal to clean out the residue. Machine replacement refers to using a flushing machine, which generates pressure to push out the old oil and refill with new oil, achieving a replacement rate of around 80%.

What are the differences between disc brakes and drum brakes?

Compared to drum brakes, disc brakes have a simpler structure and are easier to maintain. When achieving the same braking torque, the differences between disc and drum brakes are as follows: 1. The diameter of the brake drum in a drum brake system can be much smaller than that of the brake disc in a disc brake system. Therefore, large vehicles designed for heavy loads, which require strong braking force, can only be equipped with drum brakes within the limited space of the wheel rim. 2. Disc brakes have better heat dissipation than drum brakes, making them less prone to brake fade and failure during continuous braking. The disc brake system responds quickly and can perform high-frequency braking actions, making it more suitable for ABS system requirements. Disc brakes do not have the self-energizing effect of drum brakes, resulting in more balanced braking force between the left and right wheels.

The Meaning of 4MATIC?

4MATIC refers to Mercedes-Benz's four-wheel drive technology. More information about 4MATIC is as follows: 1. The core technology of Mercedes-Benz 4MATIC four-wheel drive is the 4ETS differential limiting technology. 4ETS utilizes the automatic braking force distribution function of ABS to achieve differential limiting. When a wheel of this full-time four-wheel drive vehicle slips, the onboard computer uses ABS to brake the slipping wheel, thereby limiting the idle rotation. 2. The 4MATIC full four-wheel drive system is designed to be compact and lightweight, while also offering optimized performance in terms of friction. Compared to other full four-wheel drive systems, its advantages are quite significant.
