Why does the car shake at idle?

The reasons for car shaking at idle are: 1. Excessive carbon deposits. Severe carbon buildup inside the engine cylinders can cause spark plug blockage and valve blockage; 2. Fuel supply system failure. Unstable oil pressure can easily lead to unstable mixture concentration; 3. Aging engine mounts; 4. Issues with the ignition coil or spark plugs failing to fire for some reason. Idle refers to the engine running without any load, only overcoming the frictional resistance of its internal components, without delivering external power. The minimum speed required to maintain stable engine operation is called idle speed, which is one of the five basic operating conditions of an engine. A well-functioning engine typically has an idle speed of 550 to 800 revolutions per minute. The idle speed can be adjusted by altering the throttle opening size, idle fuel supply, etc.

Why does the thermostat of Geely Vision not open after replacing the coolant?

The reasons why the thermostat of Geely Vision does not open after replacing the coolant are as follows: Internal damage to the thermostat: The thermostat automatically adjusts the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it will seriously affect the normal operation of the engine. Damage to the thermostat opening valve: If the main valve of the thermostat opens too late, it will cause the engine to overheat; if the main valve opens too early, it will prolong the engine warm-up time, resulting in the engine temperature being too low. Air not completely purged: If the air is not completely purged after replacing the coolant in the Geely Vision, it will cause the thermostat not to open.

What is the reason why the BMW ignition brake cannot be pressed down?

BMW ignition brake cannot be pressed down due to problems with the brake hydraulic system, causing excessive pressure; the newly replaced brake discs have not been adjusted, resulting in the inability to press down. Brake hydraulic system failure: The car's vacuum booster pump leaks or malfunctions. The force applied to the brake pedal is amplified by the brake booster pump. If it fails, the brake loses its assist, making it difficult to press down. Newly replaced brake discs: New brake pads require a break-in period of 200 kilometers to achieve optimal braking performance. Therefore, it is recommended to drive cautiously after replacing new brake pads.

How to Reset the Tire Pressure on a RAV4?

Method to reset the tire pressure on a RAV4: After the tire pressure monitoring system alarm is triggered, promptly check and replenish the tire pressure. Only continue driving after confirming the tire pressure is normal. The tire pressure monitoring system will automatically reset after the vehicle has been driven for a certain distance. The RAV4 utilizes a direct tire pressure monitoring system, which employs pressure sensors installed in each tire to directly measure the tire pressure. In terms of powertrain, the RAV4 is equipped with either a 2.5L gasoline engine or a 2.5L hybrid system. The 2.5L engine delivers a maximum power of 154 kW and is paired with an 8-speed automatic transmission, while the 2.5L hybrid system's engine produces a maximum power of 160 kW and is matched with an eCVT transmission.

Can China III Motorcycles Be Registered?

China III motorcycles cannot be registered. Here are the details: Introduction: China III motorcycles refer to those produced in accordance with the 'Emission Limits and Measurement Methods for Motorcycle Pollutants' and 'Emission Limits and Measurement Methods for Moped Pollutants' (collectively known as the China III Standard), approved and issued by the National Environmental Protection Agency. Starting one year after the specified type approval implementation date, all manufactured, sold, and registered motorcycles and mopeds must meet the above emission standard requirements. Note: Domestically manufactured and sold motorcycles and mopeds currently adhere to the China II emission standard. According to newly enacted regulations, newly designed vehicles must comply with the China III standard and be mass-produced accordingly. All manufactured, sold, and registered motorcycles and mopeds must also complete the transition to meet the China III emission requirements within a specified timeframe.

Why is the speedometer of BMW e46 not working?

The reasons for the speedometer needle not moving are as follows: Check the flexible shaft connection: First, check if the flexible shaft connection is disconnected, then see if the mileage starts to increase. If only the speedometer is not working, then it can only be replaced with a new one. Another possibility is that there is a foreign object stuck inside the instrument, preventing it from moving. Open the instrument to remove the foreign object, and it should work. Foreign object inside the dashboard: The speedometer is generally located inside the instrument panel, symmetrically placed with the speedometer and odometer. Most cars have electronic speedometers, which can be either pointer-type or LCD digital display-type. A foreign object inside the dashboard can cause the needle to fail to rotate. There may also be issues with the wiring inside the speedometer, such as aging or burning out.
