What type of vehicle is the Roewe RX3?

Is it normal for brake discs to rust after a car has been parked for a long time?

It is normal for brake discs to develop a ring of rust when the car is parked in a place with high humidity for an extended period. Below is some relevant information about brake pads: 1. Classification of brake pads: Asbestos brake pads (mostly phased out), semi-metallic brake pads, low-metallic brake pads, NAO formula brake pads, ceramic brake pads, NAO ceramic brake pads. 2. Ceramic brake pads vs. traditional brake pads: In traditional brake pads, metal is the main material that generates friction, providing strong braking force but with high wear and a tendency to produce noise. After installing ceramic brake pads, abnormal squealing (clicking sounds) will not occur during normal driving. Since ceramic brake pads do not contain metal components, they avoid the metal screeching noise caused by friction between traditional metal brake pads and their counterparts (i.e., brake pads and brake discs). 3. Stable friction coefficient: Ordinary brake pads have immature friction materials, and a friction coefficient that is too high can lead to unsafe factors such as loss of control during braking, pad burning, and scratching of the brake discs. Even when the brake disc temperature reaches as high as 650 degrees, the friction coefficient of ceramic brake pads remains around 0.45-0.55, ensuring the vehicle maintains good braking performance.

Is a car tire pressure of 272 kPa normal?

Not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5 bar. Tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep" sound, then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the fault light on the dashboard will turn off, completing the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Generally, an alarm will sound if the pressure is below 1.8 bar or above 3.0 bar. At this time, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to turn on. At this time, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged while driving, it will also cause the tire pressure fault light to turn on. For sensor damage issues, only a new replacement part can be installed.

How long can a 60km range last?

A range of 60KM means the vehicle can still travel 60KM. If driving at a speed of 60KM per hour, the car can run for one more hour. The actual duration depends on real-time speed. In practical use, the displayed range is not accurate, and the actual distance traveled is usually less than shown. To improve range, follow these tips: 1. Maintain medium-low speed. 2. Drive at a constant speed. 3. Reduce vehicle load. 4. Avoid sudden acceleration or braking during the trip. Note: The maximum battery-supported range refers to the highest distance the vehicle can travel in pure electric mode relying solely on battery power.

How Does an Automotive Ignition System Work?

When a gasoline engine operates, the combustion of the air-fuel mixture is controlled by the spark plug ignition. The working principle of the ignition system is to supply the spark plug with high-voltage electricity of sufficient energy at the appropriate moment, according to the engine's operating state and sequence, causing a spark between its electrodes to ensure the ignition of the air-fuel mixture and enable the engine to perform work. The ignition process of the ignition system can be divided into the following three stages: Stage 1: Contact closure, formation and growth of the primary current. When the contacts are closed, a low current flows through the circuit, following this path: positive terminal of the battery - ignition switch - primary winding of the ignition coil - breaker contacts - negative terminal of the battery. Stage 2: Contact opening, generation of the secondary high-voltage stage. At the instant the breaker contacts open, the distributor rotor aligns precisely with one of the side electrodes. The current path at this stage is: secondary winding of the ignition coil - positive terminal of the battery - side electrode of the spark plug - center electrode of the spark plug - high-voltage wire - side electrode of the distributor - center electrode of the distributor - secondary winding of the ignition coil. Stage 3: Spark plug discharge stage. After the spark plug is energized, a discharge spark occurs between its center electrode and side electrode, igniting the atomized gasoline under compression in the cylinder, thereby activating the engine.

What Causes the Rattling Noise in the Tiggo 8's Dashboard?

Tiggo 8 dashboard rattling specific reasons: 1. Air vent noise: Check if the air vents are loose or if a perfume bottle installed on the vent is causing the noise. Tighten the vents or pad the edges with some 3M tape. 2. Foreign objects in the storage box: The dashboard storage box may contain foreign objects causing noise, such as lighters, coins, screwdrivers, small wires, etc. 3. Loose connectors or wiring harness inside the dashboard: For vehicles with added reverse cameras, it might be due to an unplugged connector, improperly secured wiring harness or clips, or even screws left behind after modifications, which can cause noise as the vehicle vibrates during driving.

What Causes the Noise in Car Fan Blades?

The causes of noise in car fan blades are as follows: 1. Deformation of the fan blades in the air conditioning system, it is recommended to replace the fan. 2. Damage to the motor of the fan in the air conditioning system, it is recommended to replace the fan. 3. Excessive impurities in the air conditioning system, it is recommended to clean the air conditioning system. More details are as follows: 1. The car radiator consists of three parts: the inlet chamber, the outlet chamber, and the radiator core. The coolant flows inside the radiator core, while air passes outside the radiator. The hot coolant cools down by dissipating heat to the air, and the cold air heats up by absorbing the heat from the coolant. 2. The materials and manufacturing technologies for car radiators have advanced rapidly. Aluminum radiators, with their significant advantages in material lightweighting, are gradually replacing copper radiators in the passenger car and light vehicle sectors. Meanwhile, copper radiator manufacturing technology and processes have made substantial progress, with copper brazed radiators showing clear advantages in engine radiators for buses, construction machinery, and heavy-duty trucks. 3. Overseas passenger cars are mostly equipped with aluminum radiators, primarily for environmental protection reasons (especially in Europe and the United States). In Europe, aluminum radiators account for an average of 64% of new passenger cars. 4. From the perspective of the development prospects of China's car radiator production, brazed aluminum radiators are gradually increasing. Brazed copper radiators are also being applied in buses, trucks, and other engineering equipment.
