What Causes the Abnormal Metallic Friction Sound in the Engine?

The causes of abnormal metallic friction sounds in the engine are as follows: 1. Valve noise: During cold starts, when both water and oil temperatures are low, if the viscosity and lubrication of the engine oil are insufficient, the tappet cannot adjust properly, resulting in metallic friction sounds during cold starts. 2. Hydraulic lifter: It could be due to the hydraulic lifter—either the oil pressure is too low or the lifter itself is worn. Once air enters the lifter, a metallic friction sound will occur when starting the car. 3. Front cover assembly issue: If the engine front cover is not properly installed, the output power increases during cold starts, leading to a corresponding increase in engine noise. This is normal, but if the noise is excessive, you can report this condition during maintenance.

How about using dry ice to remove carbon deposits?

Dry ice can effectively remove carbon deposits. Here is a detailed introduction to dry ice carbon deposit removal: 1. Cleaning process: During the entire cleaning process, when the high-speed sprayed dry ice particles collide with the dirt particles, the angular momentum of the dry ice particles is transferred to the dirt particles, causing the dirt to break away from the adhesion force on the object's surface, thereby allowing the solid particles to detach from the object's surface. 2. Effects: Reduces the damage of carbon deposits to engine efficiency, restores the engine's combustion efficiency, quickly restores the vehicle's original performance, ensures smooth acceleration, reduces exhaust emissions, and effectively controls environmental pollution.

What are the question types in the Subject 4 exam?

The following is an introduction to the questions in the Subject 4 exam: 1. Question types: The main question types in Subject 4 include safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and post-accident disposal knowledge. 2. Introduction: The content of the driver's license Subject 4 exam is a theoretical test, specifically the driver's theory exam. Subject 4 is an additional safety and common sense test following the Subject 3 exam. Officially, there is no 'Subject 4' designation; the test paper consists of 50 questions, primarily in the form of case studies, pictures, animations, etc., with a full score of 100 points and a passing score of 90.

What is the reason why the Volkswagen CC parking assist system cannot be used?

Volkswagen CC parking assist system failure may be caused by line or control unit failure. It is recommended that the owner go to a repair shop or 4S store for inspection in time to avoid affecting the car experience. The following is a partial introduction of the parking assist system: 1. Introduction: The parking assist system, also known as the parking radar system, can inform the driver of the surrounding obstacles through sound and visual display. It eliminates the troubles caused by the driver looking around when parking, reversing and starting the vehicle, helps the driver eliminate blind spots, and improves driving safety. 2. Working principle: Ultrasonic detection, similar to the principle that bats can fly at high speed at night without colliding with any obstacles.

Is it okay not to change brake fluid for ten years?

It is not advisable to go without changing brake fluid for ten years, as this can cause the brake fluid to become turbid, lower its boiling point, reduce effectiveness, and may eventually lead to brake failure. The brake fluid system undergoes wear during use, and the brake fluid absorbs moisture from the air, leading to oxidation and deterioration. Therefore, it is necessary to replace the brake fluid in a timely manner to ensure driving safety. For ordinary household cars, it is recommended to change the brake fluid every two years. Brake fluid, also known as hydraulic brake fluid, is made from refined diesel fractions with thickeners and antioxidants. There are three types: mineral oil brake fluid, alcohol-based brake fluid, and synthetic brake fluid. The primary function of brake fluid is to act as a transmission medium in the automotive braking system.

Why is the engine indicator light on?

The reasons for the engine indicator light being on are: 1. Inaccurate coordination between various components of the engine leads to poor combustion state; 2. The car lacks power, and the engine noise is too loud or there is obvious knocking sound; 3. Poor fuel quality or unclean engine cylinders with severe carbon deposits. Precautions for engine maintenance: 1. Check the antifreeze in time during winter, especially in northern regions where temperatures are low. Using ordinary water instead of antifreeze can easily cause freezing, which may lead to radiator cracking, pipe blockage, and overheating; 2. The intake system needs regular inspection. A failed air filter can cause engine failure and increase carbon deposits.
