What to Do When There's Abnormal Noise in the Steering Wheel?

What Causes Smoke from the Engine Hood?

Smoke from the engine hood can occur under the following circumstances: 1. Small fuel injection advance angle: This leads to incomplete combustion; slight leakage in the cylinder liner or water in the fuel can also cause it. White smoke during cold starts, especially in low temperatures, is normal and should disappear as the engine warms up. 2. Air-fuel ratio imbalance: Decreased cylinder pressure; early fuel injection (excessive fuel injection advance angle) can cause black smoke; failure of the smoke limiter on the fuel injection pump can also result in black smoke during rapid acceleration; malfunctioning exhaust brake system. 3. Burning engine oil: Blue smoke from the car engine is often due to "burning engine oil." In such cases, check for wear in the engine cylinder liner, "stuck rings," ring alignment, aging or deformation of valve seals, excessive valve guide clearance, etc. This condition is usually accompanied by blow-by in the crankcase.

How often should the activated carbon canister be replaced?

The activated carbon canister generally needs to be replaced every 4 years or 60,000 kilometers. The carbon canister is prone to clogging, which can prevent fuel vapors from escaping, leading to excessive pressure from exhaust gases in the fuel tank. Its primary function is to reduce emission pollution. During daily use, it's important to note that the activated carbon canister should not be subjected to impacts or strong vibrations, as these can shorten its lifespan. The activated carbon canister is a container filled with activated carbon, designed to adsorb gasoline vapors escaping from the fuel tank and carburetor when the engine is turned off. When the engine is started, the adsorbed gasoline is then blown out and burned. The activated carbon canister is a crucial component in both the ignition and emission systems.

Can Modified Mid-to-Rear Exhaust Pass Annual Inspection?

Without approval from the traffic management department, modified mid-to-rear exhaust systems cannot pass annual inspection. Below is a detailed introduction to the types of car modifications: 1. Exterior Modifications: The most common exterior modifications involve installing aerodynamic kits. These kits include components such as the intake grille, side skirts, rear diffusers, and spoilers. Other exterior modifications include roof racks, sunroofs, parking distance sensors, decorative lighting, specified lighting fixtures, and side mirrors. 2. Comfort Modifications: The goal of comfort modifications is to provide the driver with a more comfortable environment and improved stability. Examples include upgrading the suspension system, interior equipment, soundproofing, window tinting, installing wider wheels, and upgrading headlights. 3. Performance Modifications: A car's power comes from the combustion of an air-fuel mixture ignited by high-voltage sparks, which pushes the pistons. Therefore, enhancing a car's performance requires upgrading various systems to increase the combustion efficiency within the cylinders.

How much fuel is left when the fuel warning light comes on?

The fuel warning light indicates there are approximately 10-12 liters of fuel remaining in the tank. It is recommended to refuel promptly when the light comes on. Here is relevant information: 1. Yellow fuel warning light: This is simply a warning designed by manufacturers for drivers who might not regularly check their fuel gauge. Refueling after the warning light comes on is considered normal practice by automakers, as the remaining fuel (about 50km range) is sufficient to locate a gas station and meet the oil pump cooling requirements. 2. Reasons for oil pressure warning light: Insufficient engine oil level reduces oil pump output or prevents pumping due to air intake, leading to decreased oil pressure.

How to Remove Stains from Leather Car Seats?

Methods to remove stains from leather car seats are as follows: 1. Stain removal cream: You can use a leather-specific stain removal cream. Never use strong stain removal products such as laundry detergent, gasoline, or chemical solvents. 2. Wipe with a towel: Simply wipe it clean with a towel. 3. Foam cleaner: Go to a car wash shop and use a foam cleaner for cleaning. Information about leather seats is as follows: 1. Precautions: Keep away from heat sources (such as cigarette butts) and strong sunlight, so it is recommended to apply window film (to block UV and infrared rays), add curtains, or use seat covers. When parking, try to choose a shady spot to avoid prolonged exposure to sunlight, which can cause the leather to fade or crack. 2. Maintenance methods: Apply a layer of polish to new leather seats to add a protective layer; perform regular maintenance by using a professional leather soft cleaner once a month for cleaning and stain removal.

How to Deal with the Lean Fuel Mixture Trouble Code?

Mainly check for any foreign objects clogging the air filter, and see if the oxygen sensor is poisoned due to fuel quality issues, leading to reduced fuel injection by the engine, or if the fuel pump is clogged by foreign objects causing low fuel pump pressure, resulting in a lean fuel mixture in the fuel system. More relevant information is as follows: 1. When the car encounters a fault: You can use the car's onboard computer to understand the cause of the fault. Professional equipment is needed to read the stored trouble codes, which can save time in diagnosing the issue. Only after understanding the trouble codes and data streams can you analyze the components that may be faulty. 2. During the use of the car: Regular maintenance is essential. Check if the fuel filter is aging and replace it promptly if necessary. During maintenance, the car's power system should also be inspected to promptly identify any potential safety hazards.
