When should the timing chain of EA888 be replaced?

For models equipped with EA888 engines before July 2012, the timing chain must be replaced after 60,000 kilometers. The relevant explanations are as follows: 1. Reason: After 60,000 kilometers, the engine's tensioner may become loose, leading to the risk of timing chain misalignment or even cylinder and valve damage. If there are symptoms such as oil loss, difficulty in starting, or sudden engine shutdown while driving, immediate replacement is necessary. 2. Precautions: During replacement, the tensioner 06H should be replaced with 06K, the timing chain should be replaced with a threaded type, and all four guides should be replaced. It is recommended to replace the entire set, including the tensioner, timing chain, balance shaft chain, plastic guides, and the lower side cover.

What does 'car coal mining' mean?

Car coal mining refers to cleaning carbon deposits. 'Coal mining' is actually a shorthand term for disassembling and cleaning the engine's intake system. During vehicle operation, as long as the engine is running, carbon deposits will form. When these deposits accumulate excessively, they can affect the engine's normal operation. Therefore, it is necessary to clean these carbon deposits regularly based on the vehicle's usage. Below are some methods for cleaning carbon deposits: In various 'auto parts markets' and 4S shops, due to technical reasons or other factors, the common method used for cleaning carbon deposits is 'intravenous injection.' However, this only addresses the symptoms, not the root cause, and is particularly ineffective for slightly older vehicles. Simply put, the reason is that these carbon deposits are too 'stubborn.'

Do tires need to be replaced after 8 years?

Tires generally need to be replaced after 8 years because the rubber deteriorates with age. The typical service life of tires is around 3 years or 80,000 kilometers. Here are the relevant details: 1. Introduction: The replacement time for tires depends on various factors such as tire brand, quality, driving conditions, and driving style, usually ranging between 50,000 to 80,000 kilometers. 2. Replacement conditions: Reaching the wear limit: Tires must be discontinued when they reach the wear limit indicator (i.e., when the tread depth is below 1.6 mm). Tire aging: Numerous small cracks appear at the base of the tread grooves or on the sidewalls. Tires with deformed treads or damaged bead areas: Tires that have been damaged by running under-inflated, leading to sidewall compression damage, or those corroded by chemicals should not be used further.

What is the ESP switch?

ESP switch has the word 'off' on it, and the related explanations are as follows: 1. Introduction: ESP can maintain the best stability of the vehicle under various conditions, and the effect is more obvious in the case of oversteering or understeering. ESP is the electronic stability program of the vehicle body, which is a general term for systems or programs aimed at improving the handling performance of the vehicle and effectively preventing the vehicle from losing control when it reaches its dynamic limit. The electronic stability program can improve the safety and handling of the vehicle. 2. Supplementary explanation: EBD is to adjust the braking force distribution to prevent the rear wheels of the vehicle from locking first. It generally fails only when the module hardware fails; ABS is to prevent the wheels from locking. By calculating the vehicle slip rate, it is controlled near the peak adhesion coefficient, which belongs to passive safety control.

What Causes the Dragging Sensation When Releasing the Throttle in a Car?

Releasing the throttle and experiencing a dragging sensation in the engine could be related to cleaning the fuel system. Improper operation or incorrect installation may lead to this issue, so it is recommended to have it checked promptly. Below is relevant knowledge about the dragging sensation: When releasing the throttle, the upshift mechanism may be triggered, causing the engine's RPM to drop naturally during upshifting. This RPM drop leads to a reduction in the engine's torque output, resulting in the engine's kinetic energy output being lower than the car's demand, hence the sensation of being dragged. This issue typically occurs between 1st to 2nd gear or 2nd to 3rd gear shifts, as the gear ratio differences between these gears are relatively large.

What is the purpose of a valve stem?

The function of a valve stem is to serve as a small component for inflating and deflating tires, while maintaining the seal after inflation. A standard valve stem consists of three main parts: the valve stem body, the valve core, and the valve cap. Below are the types of valve stems: 1. By usage: bicycle valve stems, motorcycle and electric vehicle valve stems, car valve stems, truck and bus valve stems, agricultural and engineering vehicle valve stems, and special valve stems. 2. By installation method: screw-on universal valve stems, clamp-in valve stems, and snap-in valve stems.
