What are the reasons for the abnormal noise when stepping on the brake of a Mercedes-Benz?

There are 4 main reasons for abnormal noise when stepping on the brake of a Mercedes-Benz: 1. The brake pads and brake discs need to be worn in: Brake noise in this case is relatively normal and usually disappears automatically after driving for a period of time; 2. Foreign objects: Friction from the brake pads can cause a hissing sound when braking, which increases the friction of the brake pads. In this case, the foreign objects need to be cleaned promptly, and the noise will disappear; 3. Presence of metal hard spots: There may be some small metal particles inside the brake pads, which can produce a sharp, screeching sound when lightly braking. This issue can be resolved by stepping hard on the brakes a few times, removing and regrinding the brake pads, or replacing them with better-quality brake pads; 4. Severe wear of the brake disc: Wear on the brake disc can form deep grooves around the disc, and friction between the brake pads and the edges of these grooves can cause abnormal noise. If the grooves are not particularly deep, grinding the edges of the brake pads to avoid friction with the groove edges can solve the problem. If the grooves are already very deep, it is recommended to replace the brake disc. Generally, it is advised to replace the brake disc once for every two replacements of the brake pads.

Under What Circumstances Can a Vehicle Be Declared a Total Loss?

Vehicle total loss is divided into two scenarios: one is actual total loss, meaning the vehicle is completely destroyed and cannot be repaired; the other is constructive total loss, meaning although the vehicle can still be repaired, the repair cost reaches or exceeds the actual value of the vehicle, making the repair worthless and unnecessary, thus it can be treated as a total loss. Additional information: 1. Loss calculation after total loss: According to the conventional formula, the loss amount of total loss = [New vehicle purchase price at the time of the incident - Market price of undamaged new parts] × (1 - Depreciation period × Depreciation rate) - Residual value. The new vehicle purchase price here includes the vehicle purchase tax, so the new vehicle purchase price at the time of the incident = Market price of a similar new vehicle model at the time of the incident × (1 + Vehicle purchase tax). 2. Deduction for undamaged parts: Only when the damaged vehicle has been rescued and is deemed a constructive total loss will large undamaged parts be deducted. If only small-value undamaged parts remain, they are generally included in the residual value and deducted together. In the case of an absolute total loss, the undamaged parts are zero. 3. Residual value: Refers to completely unusable scrap parts, deducted at the price they can be sold for. The ownership of the residual value is determined through negotiation between the two parties involved in the insurance. If it is assigned to the policyholder, the residual value is subtracted from the loss assessment; if it is reclaimed by the insurance company, the residual value is not subtracted. 4. Depreciation rate: Current policy terms specify a monthly depreciation rate, clearly stating depreciation according to the monthly rate and noting that the maximum depreciation amount should not exceed 80% of the new vehicle purchase price. A common point of contention here is that the annual depreciation rate calculated according to the current policy's monthly depreciation rate is generally higher than the annual depreciation rate calculated based on the national vehicle scrappage regulations.

Can a Diesel Engine with Excessive Crankcase Ventilation Continue to Be Used?

Diesel Engine with Excessive Crankcase Ventilation, the vehicle can still be used, short-term use is not a big problem, but long-term use is not recommended, because this is caused by piston ring fracture, after the fracture, the piston loses stability, so the piston impact is large and easy to break, after the fracture, the connecting rod is easy to damage the engine. Reasons for Excessive Crankcase Ventilation in Diesel Engines: 1. Severe wear of the engine piston rings and cylinder liners: Piston top burning or cylinder scoring, if the piston rings and cylinder liners are severely worn, or the piston top is burned and the cylinder is scored, it will cause the seal between the piston rings and the cylinder liners to be loose, and during the compression and expansion process of the diesel engine, a large amount of compressed gas will enter the crankcase through the small gaps between the piston rings and the cylinder liners, leading to an increase in crankcase exhaust pressure. The main symptoms include severe crankcase ventilation, insufficient engine power, and possibly blue smoke. The solution is that the engine needs at least a medium repair, and the specific situation needs to be determined by disassembling the engine. 2. Incorrect installation of engine piston rings: Piston ring alignment, if the piston rings are installed incorrectly with all openings aligned, even if the piston rings are not worn, it will cause a large amount of high-pressure gas to enter the crankcase during the compression and expansion process, resulting in an increase in crankcase exhaust pressure. Or piston ring sticking, fracture, piston ring sticking, fracture, or loss of elasticity will all lead to poor cylinder sealing, allowing combustion gases to leak into the crankcase, causing a significant increase in crankcase exhaust pressure. The solution is naturally to disassemble and reinstall. 3. Severe wear of the air compressor piston rings: Leading to air compressor blow-by, compressed gas enters the engine crankcase through the air compressor's crankshaft connecting rod mechanism, resulting in excessive crankcase exhaust. For engines equipped with an air compressor, if excessive crankcase ventilation occurs, it should also be considered whether it is caused by the air compressor. However, this situation will not cause a decrease in engine power, but the air compressor will have insufficient compressed gas, and there will definitely be engine oil inside the air passage when disassembled. The solution is to repair or replace the air compressor.

What are the two major mechanisms and five major systems of an automobile?

The two major mechanisms of an automobile engine are the crank-connecting rod mechanism and the valve train mechanism. The five major systems are the starting system, fuel supply system, cooling system, lubrication system, and ignition system. The specific introductions are as follows: Crank-connecting rod mechanism: The crank-connecting rod is an important component of an automobile engine that realizes the working cycle and completes energy conversion. It consists of the engine block group, piston-connecting rod group, and crankshaft-flywheel group. Valve train mechanism: The function of the valve train mechanism is to open and close the intake and exhaust valves according to the working sequence and process of the engine, allowing the combustible mixture or air to enter the cylinder and exhaust the waste gas from the cylinder, achieving the gas exchange process. Starting system: The process of rotating the crankshaft under external force until the engine starts to idle automatically is called engine starting. The device required to complete the starting process is called the engine starting system. Fuel supply system: The function of the gasoline engine fuel supply system is to prepare a certain amount and concentration of the mixture according to the requirements of the engine, supply it to the cylinder, and exhaust the combustion products from the cylinder. Cooling system: The function of the cooling system is to dissipate the heat absorbed by the heated parts in time to ensure that the engine works at the most suitable temperature. The cooling system of a water-cooled engine usually consists of a cooling water jacket, water pump, fan, radiator, thermostat, and other components. Lubrication system: The function of the lubrication system is to deliver a certain amount of lubricating oil to the surfaces of relatively moving parts to achieve liquid friction, reduce friction resistance, and reduce wear of the parts. Ignition system: The ignition system is usually composed of a generator, battery, distributor, ignition coil, spark plug, and other parts.
