Why is there noise from the tires?

Tire noise is caused by foreign objects such as stones. Below is an introduction about tires: 1. Introduction: Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. They are usually installed on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain driving performance. 2. Performance: Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during use. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning ability. Additionally, they require high wear resistance, flexibility, and low rolling resistance with minimal heat generation. Half of the world's rubber consumption is used for tire production, highlighting their significant demand for rubber. 3. Specifications: Specifications indicate the geometric parameters and physical performance data of tires. Tire specifications are commonly represented by a set of numbers, where the first number denotes the tire section width and the second number represents the rim diameter, both measured in inches.

Why does the MG TCM request illuminate the engine fault light?

The engine fault light may illuminate due to the following 7 main reasons: Sensor malfunction: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors may be damaged, have poor contact, or experience signal interruption, preventing the vehicle's ECU from accurately obtaining engine data, which triggers the engine fault light. Fuel or oil quality issues: Failure to use the fuel or oil as specified by the manufacturer may cause engine wear, leading to the illumination of the fault light. Poor combustion of the air-fuel mixture: Poor combustion can cause engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Issues such as spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockage can all lead to poor combustion. Turbocharging problems: Issues with the intake turbocharging pipeline or turbocharger can also trigger the engine fault light. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If the vehicle's intake system is compromised, it may lead to engine pipeline blockage, and in severe cases, the engine fault light will illuminate. A dirty or uncleaned air filter can cause intake problems. Exhaust problems: Exhaust system faults can also trigger the engine fault light. Common causes include rear oxygen sensor failure, catalytic converter issues, exhaust camshaft or bearing failure. The catalytic converter is the most frequent culprit, often damaged by leaded gasoline, lead or silicon-based lubricant additives, physical impact, or fuel system malfunctions. Anti-theft system malfunction: If the vehicle's electronic anti-theft system fails or if the anti-theft controller does not match the engine's electronic controller, the anti-theft system may prevent the engine from operating normally, accompanied by the illumination of the engine fault light. If the engine fault light illuminates, follow these steps: First, check if the engine is running normally. Look for symptoms such as shaking or black smoke. If present, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can start, turn it off and wait 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position without depressing the clutch. The vehicle will enter self-check mode. After 5-10 seconds, observe if the fault light turns off. If the fault light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.

Do I need to replace tires with scratches?

If only the surface rubber is scratched, replacement is not necessary. However, if the scratch is deep, replacement is required. Below is an introduction about tires: 1. Introduction: Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. Typically installed on metal rims, they support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain driving performance. 2. Performance: Tires often operate under complex and harsh conditions, enduring various deformations, loads, forces, and high/low temperatures during use. Therefore, they must possess high load-bearing, traction, and cushioning capabilities. Additionally, they require high wear resistance, flex resistance, and low rolling resistance with minimal heat generation. Half of the world's rubber consumption is used for tire production, highlighting the significant rubber demand for tires. 3. Specifications: Specifications are indicative data of a tire's geometric parameters and physical performance. Tire specifications are commonly represented by a set of numbers, where the first number indicates the tire section width, and the second number denotes the rim diameter, both measured in inches.

What is the standard for pavement deflection testing?

Pavement deflection testing standard is around 290. Below is an introduction to deflection: 1. Introduction: Rebound deflection refers to the vertical deformation of the subgrade or pavement under a specified load that can recover after unloading. 2. Principle: It refers to the vertical deformation of the subgrade or pavement under a specified load that can recover after unloading. The rebound deflection value of the pavement not only reflects the overall stiffness and strength of the subgrade and pavement structure but also has a certain intrinsic connection with the service condition of the pavement. 3. Characteristics: Rebound deflection is also easy to test, so the current asphalt pavement design method in China adopts the design deflection as the design index for the overall stiffness of the pavement. The design standard is that the rebound deflection value Ls of the pavement surface under the standard axle load does not exceed the pavement design deflection value Ld that meets the service condition and design service life requirements of the pavement.
