What Causes a Car to Stall After Jerking?

What are the causes of poor valve sealing?

The causes of poor valve sealing are: 1. Insufficient valve clearance; 2. Excessive carbon buildup on the valve contact surface; 3. Deformation of the valve seat or valve head; 4. Valve spring failure or rocker arm deformation. The throttle valve is a controllable valve that regulates air intake into the engine. Its function is to control the air entering the engine, which mixes with gasoline in the intake manifold to form a combustible mixture for combustion and power generation. The steps for cleaning the throttle valve are: 1. Open the engine hood and locate the throttle valve; 2. Use a flat-head screwdriver to remove the air filter and intake pipe, then unplug the electrical socket on the throttle valve; 3. After removing the screws, take off the throttle valve and use a dry cloth to block the engine intake to prevent dirt from entering; 4. Spray the throttle valve with cleaner and clean it thoroughly.

What does AO on tires stand for?

AO on tires stands for Audi Original, which is the mark of Audi's original tires. These tires undergo more than two years of rigorous testing across 50 criteria, including traction, off-road performance, grip, strength, and fatigue resistance. Additionally, they must pass stricter drainage and high-speed stability tests than industry standards. Only then are they selected and recommended by Audi's global engineering certification system, and the unique AO certification mark is imprinted on the tires. Tires with the AO marking can be installed on vehicles of brands other than Audi. When using tires with special markings, it is essential to ensure that two tires with the same special marking are installed on the same axle.

When choosing tires, it is recommended that car owners opt for well-known brands to ensure quality, as the performance of tires directly affects driving safety and experience. Car owners should not choose tires blindly but should understand which type is more suitable for their needs. Tires are ring-shaped elastic rubber products mounted on various vehicles or machinery, usually installed on metal rims. They support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure the vehicle's driving performance.

What does the tire size 215/55R16 mean?

The tire size 215/55R16 means: 215 represents the tire's section width in millimeters, 55 represents the aspect ratio (the percentage of the tire's section height divided by its width), R stands for radial tire, and 16 indicates the rim diameter in inches. The sidewall of a tire contains many important pieces of information, such as tread pattern, size specifications, recommended tire pressure, manufacturing date, speed rating, and load index. Tires are the only part of a vehicle that makes contact with the road, playing a crucial role in driving stability and safety. Being rubber products, tires are subject to aging over time, so they need to be replaced regularly.

What to Do If the Wheel Hub is Scratched?

If the wheel hub is scratched, it requires grinding, polishing, and painting of the wheel hub. For severe or deep scratches, replacing the wheel hub is necessary. Methods for self-repairing the wheel hub: 1. Clean the wheel hub; 2. Use water sandpaper dipped in water to sand the scratched area; 3. After the putty dries, gently sand the scratched area with water sandpaper dipped in water until the surface is smooth; 4. Apply paint and varnish. Precautions for using the wheel hub: 1. When the wheel hub is at a high temperature, allow it to cool naturally before cleaning. Do not use cold water for cleaning as it may damage the aluminum alloy wheel hub; 2. If there is stubborn tar on the wheel hub that cannot be removed with regular cleaners, use a brush to clean it. Avoid using overly stiff brushes as they may damage the wheel hub surface.

What brand is Laufenn tires?

Laufenn is a new sub-brand launched by Hankook Tire, offering a product line that covers passenger cars, SUVs, and light trucks, providing various products such as summer tires, winter tires, all-season tires, and all-terrain tires for these vehicles. Founded in 1941, Hankook Tire is a Korean tire manufacturer that supplies radial tires for passenger cars, light trucks (SUVs, RVs, etc.), trucks, buses, and specialized racing vehicles. Hankook has five R&D centers worldwide to ensure its tires meet the needs and enhance customer satisfaction in each region. Hankook Tire products are available in 180 countries and regions globally and entered the Chinese market in 1996. Laufenn tires focus on handling performance. Besides Laufenn, Hankook Tire also has several other sub-brands like Ventus, Dynapro, Enfren, Kinergy, and Optimo, catering to different consumer needs such as low fuel consumption, handling, noise reduction, and grip. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must have high load-bearing capacity, traction, and cushioning performance, along with high wear resistance and flex resistance, as well as low rolling resistance and heat generation. They directly contact the road surface and, together with the car's suspension, cushion the impact during driving, ensuring good ride comfort and smoothness. They also ensure good adhesion between the wheels and the road, improving the car's traction, braking, and off-road capability while bearing the vehicle's weight. Laufenn tire maintenance methods: Increase awareness of tire safety and inspect tires regularly. Regularly adjust wheel balance. Unbalanced wheels can cause high-frequency oscillations at high speeds, leading to uneven tire wear. Rotate tires periodically. To ensure even wear on all tires of the same vehicle, rotate them every 5,000 kilometers. In daily use of Laufenn tires, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to wear, the tread grooves gradually become shallow. If the tread is worn flat, it loses its drainage and anti-slip functions, significantly reducing the car's performance. Small cracks can be hidden dangers for blowouts at high speeds. Additionally, remove pebbles from the grooves immediately. Park on flat ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that can deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool tires. In hot weather or during high-speed driving, tires can overheat, increasing pressure. In such cases, stop to let them cool naturally. Avoid deflating or splashing water to cool them, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent or hard braking to prevent accelerated tread wear due to dragging between the tires and the ground.
