Methods to identify a faulty charcoal canister: The fuel nozzle may click off prematurely during refueling. The charcoal canister is part of the vehicle's evaporative emission control system, serving as a fuel vapor adsorption and desorption device. It helps reduce emissions of gasoline vapors from the fuel tank and carburetor, and is installed between the fuel tank and the engine. Working principle of the charcoal canister: 1. After the engine is turned off, gasoline vapors mix with fresh air inside the canister and are stored in the activated charcoal; 2. When the engine starts, the solenoid valve between the activated charcoal canister and the intake manifold opens, allowing the gasoline vapors in the canister to be drawn into the cylinders by the intake vacuum for combustion, mixed with clean air.

What should the tire pressure be for a BMW 530li?

The normal tire pressure range for a BMW 530li is between 2.2-2.5 bar. Tire pressure refers to the air pressure inside the tire, and the level of tire pressure plays a significant role in the performance and power of the car. If the tire pressure is too high, the contact area between the tire and the ground will decrease. During driving, the pressure per unit area on the tire will be greater. If the car is driven on rough roads, protrusions on the ground may cause the tire to burst, posing a safety risk. If the tire pressure is too low, the contact area between the tire and the ground will increase. While driving, the tire will generate high temperatures. Prolonged driving under such conditions can cause the inner side of the tire to deform, shortening the tire's lifespan and increasing the car's fuel consumption.
