Engine cylinder gasket oil leakage may be caused by moisture and oil in the main air source or excessive lubricant in the pipeline oil mist separator. Hazards of engine cylinder gasket oil leakage: A leaking cylinder gasket reduces the engine's sealing performance, leading to decreased cylinder pressure. Lower cylinder pressure results in insufficient engine power. If the engine's cylinder gasket is leaking oil, it must be replaced immediately, as prolonged use can easily cause cracks in the cylinder gasket. Reasons for cylinder gasket cracks: A car's engine is not a single unit; it consists of four components, listed from top to bottom: valve cover, cylinder head, cylinder block, and oil pan. The cylinder gasket is the sealing pad between the engine's cylinder head and cylinder block. During engine operation, the cylinder gasket is subjected to high temperatures and pressures, making it normal for cracks to develop after prolonged use.

What is the fuel tank capacity of the Lynk & Co 02?

Lynk & Co 02 has a fuel tank capacity of 50 liters, which is the officially announced data. Owners who have purchased the Lynk & Co 02 can also check this information on the vehicle's configuration sheet. The recommended fuel grade for the Lynk & Co 02 is 95 octane, with a fuel consumption of 6.4L per 100 kilometers. A full tank can provide a driving range of approximately 781 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level to the tank opening, which is designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

What are the causes of poor engine idling?

Poor engine idling is mainly caused by the following reasons: 1. Leakage in the intake system or vacuum system; clogged air filter; malfunctioning idle control valve or auxiliary air valve. 2. Faulty air flow meter; improper idle adjustment; too low fuel pressure. The following are several inspection methods for poor engine idling: 1. First, perform fault self-diagnosis to check if any fault codes appear. 2. Check for leaks in the intake system's pipe joints, vacuum hoses, exhaust gas recirculation system, and fuel vapor recovery system. 3. Check the high-voltage spark; if the spark is too weak, inspect the ignition system.

What are the reasons why the GAC GS4's one-button start fails to ignite?

The reasons why the GAC GS4's one-button start fails to ignite are as follows: 1. Battery depletion. Failure to start may be caused by the headlights being left on for a long time or the battery reaching the end of its lifespan, resulting in insufficient power for the one-button start. In this case, simply replace the battery according to the maintenance manual. 2. Out of fuel. If the fuel gauge shows below the red line, the car naturally won't start. Refueling the car will solve this issue. 3. Lack of antifreeze. Some car owners use water or low-quality antifreeze, which can cause the entire cooling system to freeze in extremely cold winter conditions, leading to engine cracks and preventing the car's water pump from functioning. This not only prevents the car from starting but also damages other engine components. It is recommended to troubleshoot the issue first and then add high-quality antifreeze. 4. Excessive carbon buildup. Too much carbon buildup in the vehicle can also prevent it from starting. Regular cleaning of carbon deposits at a service center is necessary. 5. Spark plug issues. The spark plug is a critical component of the car's ignition system, so its proper functioning directly affects the vehicle's performance and efficiency. If the spark plug has problems, it is advisable to replace it promptly.

What are the requirements for a large-displacement motorcycle license?

In China, motorcycle driver's licenses are not categorized by engine displacement. Here's why: 1. Motorcycle licenses are primarily related to vehicle type rather than displacement. Currently, China has three types of motorcycle licenses: F, E, and D. 2. An F license only permits riding light motorcycles with engine displacements below 50CC. An E license allows riding any two-wheeled motorcycle regardless of displacement. A D license permits riding all two-wheeled and three-wheeled motorcycles. Therefore, with an E license, you can ride all two-wheeled motorcycles, including large-displacement models, as there is no separate license specifically for large-displacement motorcycles.
