What is the reason for the occasional jerking during cold starts of the BMW 3 Series?

BMW 3 Series may jerk during cold starts due to low-temperature starting and high engine RPM. Symptoms of jerking: When the car is started cold or at relatively low temperatures, symptoms such as engine shaking, high idle speed, transmission hesitation, and brake noise may occur. These are often accompanied by a strong odor of unburned gasoline and black smoke. Reasons for jerking: High RPM: It is normal for the idle speed to be higher during startup. The car requires higher RPM to allow the engine to reach normal operating conditions quickly, which necessitates a richer air-fuel mixture. As a result, both air intake and fuel injection are increased, leading to higher RPM. The colder the weather and the lower the water temperature (compared to the normal engine operating temperature, typically around 85 to 110 degrees Celsius), the greater the temperature difference from normal engine operation. The car's computer will control a higher cold-start idle speed, meaning the engine RPM will be higher when first started. Under normal circumstances, depending on the water temperature, the engine's cold idle speed will gradually decrease from over 1200 RPM until the engine reaches its normal operating temperature and stabilizes at the standard idle speed of around 800 RPM. The solution is to clean the throttle body promptly, which generally resolves the issue.

How to Check the Production Date of Truck Tires?

On the sidewall of a car tire, within a small square, the production date of the tire is marked, consisting of four digits. The last two digits represent the year, and the first two digits represent the week number. Below is a detailed introduction about car tires: 1. Overview: Car tires are one of the important components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help to cushion the impacts encountered during driving, ensuring good ride comfort and smooth driving. 2. Function: They ensure good adhesion between the wheels and the road surface; improve the vehicle's traction, braking, and off-road capability; and bear the weight of the car. The important role tires play in vehicles is increasingly being recognized by people.

How to open the hood of an Audi RS5?

Audi RS5 hood opening procedure: On the left side of the driver's seat near the knee area, there is a switch. Press the switch to slightly pop up the hood (releasing the first lock); Then insert your hand into the front gap of the hood and push a lever to the right (releasing the second lock); After that, you can lift the hood. Below is relevant information about the hood: 1. The hood is made of rubber foam and aluminum foil materials, which can reduce engine noise while isolating heat generated during engine operation, effectively protecting the paint surface on the hood and preventing aging. 2. The hood can direct airflow. For objects moving at high speed in the air, the air resistance and turbulence generated around the moving object will directly affect its trajectory and speed. The shape of the hood can effectively adjust the direction of airflow relative to the car's movement and the resulting resistance, reducing the impact of airflow on the car. Through airflow guidance, air resistance can be decomposed into beneficial forces, increasing the front tires' grip on the ground and improving driving stability. The streamlined appearance of the hood is basically designed based on this principle. 3. The hood serves to protect the engine and surrounding pipeline components. Under the hood are critical components of the car, including the engine, electrical circuits, fuel system, braking system, and transmission system, which are vital to the vehicle. By enhancing the strength and structure of the hood, it can effectively prevent adverse effects such as impacts, corrosion, rain, and electrical interference, ensuring the normal operation of the vehicle.
