Idling with the air conditioning on for 3 hours will increase fuel consumption, and over time, the engine is prone to carbon buildup. Additionally, if you sleep in the car, there is a risk of poisoning, which is very dangerous. The car air conditioning system is designed to cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and enhancing driving safety. If the car needs to stop briefly, idling is an option. However, for longer stops, it is recommended to turn off the engine to wait. This not only reduces fuel consumption but also protects the environment and prevents carbon buildup in the engine.

Is the BMW N20 engine oil temperature around 125 degrees?

For the BMW N20 engine, an oil temperature between 100-120 degrees is normal. Normal range of oil temperature: An oil temperature of 100 degrees is normal. The working temperature of engine oil is generally between 70 to 90 degrees. During aggressive driving, it can reach around 100 to 110 degrees. If the oil temperature consistently stays above 120 degrees, it requires immediate inspection, as it can cause various adverse effects. Effects of excessively high oil temperature: It affects the viscosity of the oil, leading to severe wear of some engine components, and in serious cases, may cause cylinder scuffing or bearing seizure. It can also cause the fuel injected into the cylinder to ignite prematurely, resulting in insufficient compression and reduced power output.

How Many Patents Does Volkswagen Have?

SAIC Volkswagen has 1,630 patents. Patent: A patent is generally a document issued by a government agency or a regional organization representing several countries based on an application. This document records the content of an invention or creation and establishes a legal status for a certain period, meaning that others can only implement the patented invention or creation with the permission of the patent holder under normal circumstances. Valid Patent: A patent that remains in effect after being granted. To keep a patent valid, it must still be within the statutory protection period, and the patent holder must pay the annual fees as required. Expired Patent: After a patent application is granted, if it exceeds the statutory protection period or the patent holder fails to pay the annual fees on time, resulting in the loss of patent rights, or if any individual or entity requests the patent to be declared invalid and the Patent Reexamination Board confirms and declares it invalid, the patent is then referred to as an expired patent.

Where is the throttle body located?

The throttle body is located behind the air filter in the intake system and in front of the intake manifold. The throttle body is the throat of the engine, controlling the amount of air entering the engine. When the driver presses the accelerator pedal, it doesn't directly control fuel injection but rather adjusts the throttle opening. When the throttle opening increases, sensors detect the increased airflow and command the fuel injection system to increase fuel delivery. Modern engines use electronic throttle bodies. The crankcase ventilation tube connects to the throttle body for both environmental reasons and to utilize intake vacuum for drawing gases from the crankcase. When oil vapors reach the intake tract, they cool down, causing oil to condense on intake passages and the throttle body. Carbon deposits carried by these vapors also accumulate in these areas. Since the throttle opening has the highest airflow velocity, smallest space, and lowest gas temperature, this area is most prone to condensation buildup. Therefore, how quickly the throttle body gets dirty depends on multiple factors including air filter quality, engine oil brand/quality, driving conditions, ambient temperature, engine operating temperature, and driving habits.

How many liters of fuel does the 2018 Civic need?

The 2018 Civic's fuel tank requires 47 liters of fuel. The manufacturer recommends using 92-octane gasoline. For safety, the car must be turned off before refueling, and the fuel tank cap can be opened by pressing it without locking the car. Honda Civic refueling procedure: 1. Press the left side of the fuel tank to open the fuel cap; 2. Unscrew the fuel tank sealing cap counterclockwise; 3. Insert the fuel tank sealing cap into the fuel tank cover; 4. Insert the fuel nozzle into the fuel tank; 5. Start refueling. When the fuel nozzle is cut off for the first time, the tank is full. Continuing to refuel will fill the expansion chamber in the fuel tank; 6. Do not pull out the fuel nozzle immediately. Leave it at the fuel port for 5 seconds to allow all fuel to drain into the tank; 7. Screw the fuel tank sealing cap clockwise onto the fuel port until a click is heard; 8.
