Which letter indicates the maximum speed of a tire?

Tire maximum speed codes: Q, R, S, T, U, H, V, W, Y. The maximum speed of a tire is indicated by a letter code, with different letters representing different speed ratings and corresponding maximum speeds. Q represents 160 km/h, R represents 170 km/h, S represents 180 km/h, T represents 190 km/h, U represents 200 km/h, H represents 210 km/h, V represents 240 km/h, W represents 270 km/h, and Y represents 300 km/h. Generally, P-T (150-190 km/h) tires are suitable for small and compact cars, U-V (200-240 km/h) tires are suitable for mid-to-high-end cars, while W-Z (270 km/h+) are used for large luxury sedans and sports cars.

How often should Motul 7100 oil be changed?

Motul 7100 oil should be changed every 2000 kilometers. Motul oil change intervals: Motul can meet the requirements, and the oil change intervals for Motul oils are generally long. From the perspective of the oil itself, changing it every 8000 to 10,000 kilometers is not a problem, but the lifespan of the engine's surrounding components should also be considered. Motorcycle-specific oil: Motul 7100 oil is specifically designed for motorcycles, while Motul 8100 is for cars. However, since Motul oil is a Group V ester-based oil, the change interval typically does not exceed 3000 kilometers. Considering cost-effectiveness, Motul oil is not suitable for household cars. Besides Group V base oils, there are also Group IV PAO base oils with strong performance, such as the representative imported GT Magic Red, which are high-end oils that balance both power and mileage.

What is the purpose of a front splitter?

The purpose of a front splitter is primarily decorative. Adding a front splitter can make the vehicle look more aesthetically pleasing, but its practical effect in terms of modification is actually quite limited—it mainly adds a bit of personality to the exterior. Car modification refers to altering the external appearance, interior design, and mechanical performance of a factory-produced vehicle according to the owner's preferences. It mainly includes two types: body modifications and performance modifications. Front splitters are typically made from materials such as fiberglass (resin fiber), one-time molded PP (polypropylene), or PU (polyurethane). PU material, which is a type of soft rubber, is the most commonly used due to its high flexibility and resistance to damage from minor scrapes. However, it cannot withstand high-temperature paint baking as it may deform, and front splitters tend to be relatively heavy. The downside of installing a front splitter is that it can easily get knocked off or scraped when driving on rough or uneven roads. For many car modification enthusiasts, a front splitter is considered an aesthetic accessory that enhances the overall appearance of the vehicle. In racing cars, the front splitter serves as an aerodynamic component, designed to reduce the amount of air passing under the chassis, thereby improving stability at high speeds.

What Happens When a Car Runs Out of Engine Oil?

Running out of engine oil can lead to the following symptoms: 1. The lubrication effect deteriorates significantly. In severe cases, the lack of lubrication can cause engine seizure, and the consequences worsen as the oil level decreases. 2. When the engine is restarted, dry or semi-dry friction occurs between the cylinders and pistons, accelerating component wear. The increased resistance also makes starting the engine more difficult. Here are the functions of engine oil: 1. Reduces wear: There is rapid relative sliding between pistons and cylinders, as well as between crankshafts and bearings. Engine oil prevents excessive wear of these components. 2. Cools the engine: Engine oil assists the radiator in cooling the engine by dissipating heat. 3. Seals and prevents leaks: Engine oil forms a sealing ring between piston rings and pistons, reducing gas leakage and preventing contaminants from entering. 4. Dampens vibrations: When pressure in the engine cylinder rises sharply, the load on pistons, piston rings, connecting rods, and crankshaft bearings increases suddenly. The lubricated bearings help cushion the impact load.

What do the numbers 35, 40, and 50 at the back of Audi mean?

Audi's numbers 35, 40, and 50 represent engines with different power outputs. Generally, 35 stands for 1.4T, 40 for 2.0T low power, 45 for 2.0T high power, and 50 for 3.0T. These numbers indicate the g-value, reflecting the car's acceleration. The higher the number, the greater the horsepower and the better the performance. Audi's lineup includes models such as the A4L, A3, Q5, Q7, and S3. The Audi A4L, for example, has a body length of 4858mm, width of 1847mm, height of 1439mm, and a wheelbase of 2908mm. It is equipped with a 2.0T turbocharged engine paired with a 7-speed dual-clutch transmission. This engine delivers a maximum power of 110kW and a maximum torque of 270Nm.

What are the items included in the third maintenance of the Tayron?

Tayron third maintenance items: 1. Replace engine oil, oil filter, fuel filter, air filter, cabin air filter, transmission fluid, coolant, and brake fluid. 2. Clean the throttle intake manifold and three-way catalytic converter. 3. The Tayron's third maintenance is performed when the vehicle has traveled 36,000-40,000 kilometers to consolidate and maintain the normal operation of various components. Below is relevant information about the Tayron's third maintenance: 1. In addition to all the items covered in the first and second maintenance, the third maintenance includes inspecting the engine, cleaning carbon deposits, gum deposits, and the cooling system. 2. Perform cleaning and inspection of the chassis assembly, check for paint peeling on the vehicle body, and inspect tires for abnormalities. 3. The most critical part is the engine, which involves cleaning and disassembling the engine, removing carbon deposits and oil sludge, disassembling and cleaning the air filter, replacing engine oil, checking the air compressor's working condition, and inspecting the sealing performance of pipelines. 4. Inspect the overall body, including the front face, fenders, cab, doors, and cargo compartment for paint condition, and perform touch-ups as needed. Remove fine sand and stones from tires, and check for bulges, delamination, cracks, deformation, or aging.
