Are OEM wheels made by casting or forging?

OEM wheels are made by casting. Here is some related information about wheels: Introduction: A wheel hub is the rotating part that connects the tire's inner contour to the wheel's core via pillars, i.e., the metal component mounted on the axle that supports the tire. It is also called a rim, wheel ring, or wheel disc. Wheels come in various types based on diameter, width, forming method, and material. Wheel types: Wheels are also called rims. Depending on the characteristics and requirements of different vehicle models, the surface treatment process of wheels may vary, generally categorized into painting and plating. For ordinary vehicle models, wheels are less considered in terms of appearance, with good heat dissipation being a basic requirement. The manufacturing process typically involves painting, i.e., spraying followed by baking, which is cost-effective, offers vibrant colors, and maintains durability over time. Even when the vehicle is scrapped, the wheel's color remains unchanged.

What Happens When an Engine is Damaged?

Here are the situations that may occur when an engine is damaged: Sensor-related failures: such as coolant temperature sensor, crankshaft sensor, oxygen sensor, etc. Poor mixture combustion: engine spark plug failure, ignition coil failure, fuel pump failure, fuel line blockage, etc., can all cause poor mixture combustion in the engine. Air intake issues: when combustion occurs inside the engine, air intake is necessary. In this process, the air filter is very important. If the car's air filter is not clean and not regularly cleaned, it will affect the car's air intake. Over time, this can lead to blockages, and in severe cases, it can cause the engine fault light to come on. Turbocharging issues: intake turbocharging pipes and turbochargers can also cause the engine fault light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, high oil consumption, reduced power, metallic noises, and blue or black smoke from the exhaust pipe.

What Causes the Engine Sound to Fluctuate Between Loud and Quiet During Hot Idle?

When the engine is idling while hot, the sound may fluctuate between loud and quiet, but as long as the variation is not very noticeable and there is no shaking, it is considered normal. Below is an introduction to car idling: Introduction to Car Idling: Idling is a working condition of the car, referring to the engine running in neutral. The engine speed during idling is called the idle speed. The idle speed can be adjusted by modifying the throttle size, among other factors. Idling means the engine is "producing power without doing work." When the engine is running, if the accelerator pedal is fully released, the engine enters the idle state. Causes of Unstable Idling: Direct causes refer to mechanical parts being dirty, worn, or incorrectly installed, leading to changes in cylinder power and resulting in an imbalance of power among the cylinders, causing unstable idling. Indirect causes refer to abnormalities in the engine's electronic control system, leading to poor combustion of the air-fuel mixture, making it difficult to balance the power among the cylinders and causing unstable idling.

Does the fuel gauge 'E' mean full or empty?

"The 'F' in a car's fuel gauge means the tank is full, and 'E' means the fuel level is low. In a needle-type fuel gauge, when the needle points to 'F', it indicates the fuel tank is full. The closer it gets to 'E', the lower the fuel level, meaning there's less fuel. 'F' stands for full, the full term being 'FULL'. The 'F' on a car's fuel gauge is derived from the English word 'FULL', representing a full tank, while 'E' stands for 'Empty', indicating low fuel. Precautions for refueling a car: Avoid overfilling the tank: If the tank is filled too much, during summer when temperatures are high and the car itself generates heat, the gasoline expands due to thermal expansion. To prevent the fuel tank from being damaged by the expanding gasoline, there is a vent hole. If the tank is overfilled, gasoline may overflow through the vent hole, which could lead to spontaneous combustion if exposed to an open flame, with unimaginable consequences. Additionally, gasoline overflowing through the vent hole can drip onto the car body, causing some corrosion. Try to avoid waiting until the fuel light comes on to refuel: While driving, always pay attention to the fuel gauge. When the needle indicates only a quarter of the fuel is left, it's time to refuel. It's best not to wait until the fuel light comes on before refueling. Modern cars use electric fuel pumps that require gasoline for lubrication and cooling. Frequently waiting until the fuel light comes on to refuel can prevent the fuel pump from getting proper lubrication and cooling, ultimately reducing its lifespan. Choose the right time to refuel: Avoid refueling at noon. Due to thermal expansion, the volume of gasoline increases with temperature. When the temperature drops, the volume of gasoline decreases. Since refueling is billed by volume, to save money, try to refuel in the morning or evening."

Turn Signal First or Shift Gear First?

Shift gear first and then turn on the turn signal. Here is a detailed introduction about car turn signals: Overview: Car turn signals refer to the flashing indicator lights that are activated when the vehicle is turning, alerting pedestrians or vehicles in front or behind to the direction the vehicle is moving. Based on the materials used, they can be classified into car turn signals and LED car turn signals. Based on their positions, they can be divided into front turn signals, rear turn signals, and side turn signals. Principle: The lamp tube uses a xenon lamp tube, and the microcontroller controls the circuit, enabling the left and right lights to flash alternately and continuously. According to their structure, the flashers of turn signals can be divided into three types: resistance wire type, capacitor type, and electronic type.
