Causes of cylinder head gasket burning: 1. Uneven or insufficient tightening force of cylinder head bolts; deformation of the joint surface between the cylinder block and cylinder head; 2. The engine frequently operates under conditions such as heavy load, premature ignition, engine overheating, or detonation; 3. Quality issues with the cylinder gasket itself. The cylinder gasket is primarily used to ensure the sealing between the cylinder block and the cylinder head joint surface, preventing gas and water leakage. The cylinder gasket is in direct contact with high-temperature, high-pressure gas, making it prone to burning during use, especially around the rolled edges of the cylinder ports. After the cylinder gasket is burned, the engine's operating condition will severely deteriorate, and it can easily cause damage to related components or parts.

What is the speed when exceeding the 120 km/h limit by 10%?

Exceeding the 120 km/h speed limit by 10% results in a speed between 132-144 km/h. Below are the hazards of speeding: 1. Vehicle steering becomes unstable: Speeding increases the airflow speed difference between the top and bottom of the car body. This differential causes an upward lift force, reducing the vehicle's stability during driving. This is one of the main reasons for unstable steering. 2. Driving habits intensify: The faster the speed, the stronger the vehicle's inertia to maintain straight-line movement, leading to poorer directional control and significantly increased risks. If an emergency occurs ahead, it becomes difficult to control the vehicle within a short time, potentially resulting in unimaginable consequences.

What to Do When Your Driver's License Expires?

Solutions for an expired driver's license are as follows: 1. Within 1 year of expiration, bring your driver's license, ID card, and health certificate to renew the license. 2.

How Many Times Can You Take the Driving License Subject 4 Exam?

There is no limit to the number of times you can take the Subject 4 exam for the driving license, but it must be passed within the 3-year validity period of the driving test. Subject 4 can only be taken after passing the Subject 3 road driving skills test. If you fail the exam, you can apply for a retake on the same day, and the previously passed road driving skills test results will still be valid. Notes on the driving license exam: After each subject is scheduled, you can take the exam once and retake once on the same day. If you do not attend the retake or fail the retake, you must reschedule the exam. During the validity period of the driving skills test permit, the number of scheduled attempts for Subject 2 and Subject 3 must not exceed five times each (i.e., a total of ten exam opportunities). If you fail the fifth scheduled exam, the results of other subjects that have been passed will be invalidated, and the student will need to retake the exam starting from Subject 1. Subject 4 exam content: Safe and civilized driving test, with a full score of 100 and a passing score of 90. The question types for Subject 4 are multiple-choice and true/false questions, with questions mainly presented in the form of case studies, pictures, animations, etc.

What Causes the Classic Focus to Feel Sluggish and Lack Power During Acceleration?

Focus feeling sluggish and lacking power during acceleration may be due to an intake system malfunction or a fuel supply system issue. Here are some explanations regarding the Focus feeling sluggish and lacking power during acceleration: 1. Lack of Power During Acceleration and the Intake System: The air supply system primarily provides an appropriate amount of air to match the fuel, and the purity of the air directly affects combustion efficiency, which in turn influences power output. Therefore, when experiencing a lack of power during acceleration, the first step is to check whether the intake system is functioning properly. If it appears intact, consider whether the intake system needs cleaning. Remove the air filter and blow out the dust; if it cannot be cleaned thoroughly, replace it. Inspect the throttle body for cleanliness, and further examine the intake valves and intake manifold. Clean them if necessary. If the acceleration still feels sluggish after inspecting and cleaning the intake system, it can be concluded that the issue is unrelated to the intake system. General idle shaking can often be resolved by cleaning the intake system. 2. Lack of Power During Acceleration and the Fuel Supply System: The amount of fuel supplied directly determines the strength of the power output, and the complete combustion of fuel ensures consistent power. Therefore, when experiencing insufficient power, the fuel supply system should also be considered. First, ensure the fuel meets the vehicle's standards. If the fuel lines and connections are intact, inspect the fuel filter, fuel injectors, and fuel pump for any blockages in fuel delivery. Clean or replace them if necessary. Checking the fuel supply system ensures smooth fuel delivery and injection, and a properly functioning fuel pump will eliminate potential obstacles for subsequent operations.

How to Correct Direction for Front Wheel Skid and Rear Wheel Skid?

When the front wheels skid, the steering wheel should be corrected in the opposite direction; when the rear wheels skid, the steering wheel should be corrected in the direction of the skid, and the vehicle should return to the road after the rear wheels are straightened. Vehicle skidding refers to the phenomenon of sudden acceleration or sudden lateral swinging, which is more likely to occur on curves or in rainy or snowy weather. If a skid suddenly occurs while driving, the driver should try to stay calm, hold the steering wheel firmly with both hands, quickly identify which tire is skidding, immediately release the brake pedal, and swiftly turn the steering wheel in the direction of the skid. On icy or snowy roads, drivers should never use emergency braking. Emergency braking not only fails to stop the vehicle but can also accelerate skidding or even cause the vehicle to roll over. If skidding occurs while going downhill, the driver can accelerate appropriately. If skidding occurs during a turn, the driver should slowly release the accelerator and turn the steering wheel to correct the direction, but be careful not to turn the steering wheel too much to avoid losing control and causing an accident. During a skid, do not abruptly turn the steering wheel or use the foot brake. Immediately release the brake pedal, turn the steering wheel toward the side of the skid, and promptly adjust and correct the direction before continuing to drive.
