When the oil-gas separator is damaged, it can cause the engine to shake after a cold start, burn engine oil, lead to severe carbon buildup in the engine, and produce a sharp, whistle-like sound. Some vehicles may also trigger the engine fault light due to an overly rich air-fuel mixture. Here is an introduction to the oil-gas separator: 1. The main function of the oil-gas separator is to filter gases from the engine oil, ensuring optimal fluidity and lubrication performance. 2. The oil-gas separator effectively maintains the lubrication of friction components in the engine, reducing wear and corrosion caused by insufficient lubrication. Additionally, it helps maintain equal pressure between the crankcase and the atmosphere, minimizing oil leakage due to pressure differences.

What is the Vehicle Waterproof Rating?

Vehicle waterproof rating refers to the level of waterproof protection function of a vehicle. Below is relevant information about vehicle waterproof ratings: 1. IPX Rating: IPX is an internationally recognized waterproof certification system. It is commonly used to indicate the waterproof level of products such as outdoor and diving equipment, serving as the most prevalent technical indicator. The IPX waterproof rating is divided into 8 levels, ranging from IPX-1 to IPX-8, with waterproof capability increasing progressively. 2. Vehicle Waterproof Rating: New energy electric vehicles achieve an IP67 waterproof rating, allowing normal operation in 40CM deep water.

What does illegal removal of OBU mean?

Illegal removal of OBU refers to a situation where the lane system displays a U-turn or overtime vehicle, and the automatic deduction or swiping of the card to deduct the fee from the card will not be possible. In such cases, the toll should be paid in cash. Below is some relevant information about OBU: 1. Concept: It stands for On-Board Unit, which is a microwave device using DSRC technology to communicate with RSU. 2. Limitations: The in-vehicle application environment is quite harsh, so the performance requirements for in-vehicle equipment are higher than those for general electronic devices. When designing intelligent transportation systems, it is particularly important to consider the application environment to ensure the system can adapt to the in-vehicle environment and leverage it to create greater value than general systems.

What is the difference between E and F driving licenses?

The differences between E and F driving licenses are as follows: 1. Different permitted vehicle types: The E license allows driving two-wheeled motorcycles with an engine displacement over 50ml or a maximum design speed exceeding 50km/h; The F license permits driving light motorcycles with an engine displacement under 50ml and a maximum design speed not exceeding 50km/h. 2. Different driving scopes: The E license can drive both regular two-wheeled motorcycles and the light motorcycles permitted by the F license; The F license can only drive light motorcycles, with no other permitted vehicle types. 3. Different license plate colors: E license plates are yellow; F license plates are blue. 4. Different examination requirements: The E license test vehicle must be a regular two-wheeled motorcycle with at least four speed gears; The F license test vehicle requirements are formulated by the provincial traffic management department of the public security authority.

Where to Maintain a Jetta After Purchase?

Jetta vehicles should be maintained at Jetta 4S stores or auto repair shops and cannot currently be serviced at Volkswagen 4S stores. In fact, getting maintenance done anywhere will not affect the owner's "Three Guarantees" rights. China's Three Guarantees policy does not explicitly link maintenance outside 4S stores with the Three Guarantees services. The policy states that as long as maintenance is performed according to the manufacturer's requirements, the warranty remains valid, and any quality issues during the warranty period can be covered by the Three Guarantees. If a component unrelated to maintenance fails, there is no issue with receiving Three Guarantees services. However, in practice, if engine problems arise and the warranty-period maintenance was not performed at a 4S store, claiming Three Guarantees services can be somewhat troublesome. The following situations are not covered by the Three Guarantees but may be eligible for paid repairs: 1. Damage caused by improper use, maintenance, or storage by the consumer; 2. Damage caused by unauthorized disassembly by non-authorized repair providers; 3. Lack of a valid Three Guarantees certificate or purchase invoice; 4. Discrepancy between the product model on the Three Guarantees certificate and the repaired product, or if the certificate has been altered; 5. Damage caused by force majeure.

What Causes the Clicking Noise in the Front Axle of FAW J6P?

Body noise, engine compartment noise, etc. Here are the specific details: 1. Body Noise This issue is usually caused by insufficient body rigidity, leading to deformation of the vehicle during driving, resulting in friction or shaking between the doors and the frame, or friction between steel plates due to loose welds. Applying adhesive strips on the doors and windows or placing rubber pads in the friction areas may reduce or eliminate the noise, but these are temporary fixes. Some vehicles have significant wind noise, which is related to their design. If no additional items have been added, the owner should not attempt to resolve it themselves. Additionally, loose fastenings between body components can also cause noise, which can usually be fixed by tightening the screws. 2. Engine Compartment Noise: There are several possible causes for noise here. A high-pitched belt squeal is usually due to belt slippage. If there is a dry metal friction sound when the engine is running, it often indicates damage to the bearings of the generator, water pump, or power steering pump. A hissing sound during engine operation may suggest a blocked exhaust system or a leaking/broken vacuum tube. It's important to note that if the noise originates from inside the engine, the owner likely cannot fix it themselves, and it's best to take the vehicle to a repair shop. 3. Transmission Noise: If there is a "rustling" sound from the transmission while driving, which disappears when the clutch is pressed, it indicates a transmission issue, possibly due to worn bearings or gears, or bearing spots. 4. Tire Noise: Tire noise is always rhythmic, and its frequency increases with speed. A dull "thudding" sound often indicates tire tread deformation, bulging, severe wear, or insufficient pressure. A "tapping" sound may be caused by small stones stuck in the tread. If the tire makes a "whooshing" sound accompanied by noticeable body shaking or steering deviation, it's almost certainly a tire blowout, and the tire should be replaced immediately.
