What tires are suitable for the Trumpchi GS4?

The Trumpchi GS4 can choose tires with appropriate performance for replacement based on actual conditions. Below are the selection criteria for car tires: 1. Tire identification. Tires will have the production date and the "CCC certification" mark. Learning to check the manufacturing date can help avoid purchasing expired products. 2. Anti-counterfeiting marks. When selecting tires, besides checking the production date, pay attention to the anti-counterfeiting marks to avoid being deceived by sellers and buying counterfeit tires. 3. Load index and speed rating. The load index and speed rating are printed on the sidewall of the tire, with the former represented by numbers and the latter by letters. It is recommended to refer to these two parameters when selecting tires and choose suitable ones based on the vehicle's condition. 4. Tire tread pattern. The tread pattern is an important aspect reflecting tire performance. Different drivers have varying driving needs, and no single tire can cover all performance aspects. Different tires excel in different performance areas. 5. Tire brand. Each tire brand emphasizes different performance aspects. The specific choice of tire should be based on individual needs.

What Does the Octane Number of Gasoline Represent?

Gasoline octane number represents the anti-knock property of gasoline and has no relation to its cleanliness. The evaluation index for gasoline's anti-knock property is the octane number, which is also known as the gasoline grade. It represents the ratio between the actual anti-knock performance of gasoline and that of standard gasoline. Here are some introductions about gasoline octane number: 1. Standard gasoline consists of isooctane and n-heptane. Isooctane has good anti-knock properties, and its octane number is defined as 100. N-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, so its octane number is defined as 0. 2. The type of gasoline used in a car is determined by the engine's compression ratio. A higher compression ratio indicates the need for gasoline with better anti-knock properties, thus requiring the use of higher-grade gasoline.

Is it necessary to replace car brake pads at a 4S shop?

Replacing car brake pads does not require going to a 4S shop. Here is the method for replacing brake pads: 1. Open the engine compartment to check the brake fluid level to prevent overflow during replacement; 2. Remove the wheel where the brake is located; 3. Unscrew the bolts of the brake caliper and remove the brake pads; 4. Install the new brake pads, tighten the guide bolts, and the replacement is complete. Additional information: 1. The working principle of brake pads is: by utilizing the friction between the brake pads and the brake drum, as well as between the tires and the ground, the kinetic energy of the moving vehicle is converted into heat energy through friction, thereby stopping the vehicle. 2. Types of brake pads include: semi-metallic brake pads, non-metallic brake pads, carbon fiber brake pads, and ceramic fiber brake pads.

What Causes the Engine Warning Light to Illuminate on the Dashboard When the Car Is Not Started?

When the car is not started, the engine warning light illuminating is part of the vehicle's self-check process, indicating that the engine is not yet operational. Before ignition, the vehicle enters a self-check state, during which this light (the engine warning light) will turn on and will turn off after the car starts normally. Here is an introduction to car engines: 1. Working Principle: An engine is a machine capable of converting other forms of energy into mechanical energy. It originated in the UK and can refer to both the power generation device and the entire machine including the power unit (such as gasoline engines, aircraft engines). 2. Composition: Its types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), electric motors, etc.

What does the 'sport' mean on a car?

The 'sport' on a car refers to the sport mode, which is a performance-prioritized shifting mode set for automatic transmissions. Here is an introduction to car gear positions: 1. P (Park) is used when the vehicle is parked for an extended period; 2. R (Reverse) is used when the vehicle is reversing; 3. N (Neutral) is used when the vehicle is temporarily stopped; 4. D (Drive) is the forward or driving gear; 5. L (Low) is the low-speed mode, used when going uphill or downhill. Additional information: In sport mode, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high RPM for a longer period. This allows the car to maintain low gear and high RPM for an extended time, resulting in greater torque output and acceleration.
