What gas is inside a car's airbag?

Car airbags contain nitrogen gas. The airbag contains solid sodium azide (NaN3), which rapidly decomposes upon severe impact to generate a large amount of nitrogen gas. Therefore, the airbag is filled with nitrogen (NaN3 decomposes into Na and N2). Car airbags are designed to ensure the safety of drivers and passengers, so the gas used for inflation must be inert, typically nitrogen. Airbags are a passive safety technology and do not have an active switch. They deploy only when the car experiences a collision. Based on signals from sensors, the gas generator determines whether to ignite, causing the solid fuel to explode and rapidly inflate the airbag with nitrogen, while the airbag itself deploys.

What are the three pedals in a car?

The three pedals in a car are: the left pedal is the clutch pedal, the middle one is the brake pedal, and the right one is the accelerator pedal. The clutch pedal is used when starting or shifting gears. The clutch is located between the engine and the transmission, and it can connect or disconnect the engine from the transmission. The brake pedal controls the braking system; pressing it will slow down the car. The accelerator pedal is used when accelerating. It does not directly control the fuel injection volume but rather the throttle opening. When the throttle opening increases, the ECU detects this and then increases the fuel injection volume. Using the clutch pedal requires some skill. When starting the car, the half-clutch technique is needed. If the clutch pedal is released too quickly during startup, it can cause the engine to stall.

What does 'service' mean on a car?

Service on a car indicates that the vehicle needs maintenance.

What does max mean in a car?

Max in a car is the English word for maximum. In the context of a car's air conditioning system, max indicates the maximum cooling mode, where pressing the max button will activate the strongest cooling setting. If it appears on the engine oil dipstick, max refers to the maximum oil level, and when adding engine oil, you must ensure the oil level does not exceed the max mark. Car air conditioning works on the principle of refrigerant absorbing a large amount of heat when changing from a liquid to a gaseous state. The compressor, powered by the car engine via a belt, draws in low-temperature, low-pressure refrigerant gas, compresses it into high-temperature, high-pressure gas, which then cools down in the condenser's heat dissipation tubes, turning into high-pressure, medium-temperature liquid. After passing through a receiver-drier for dehumidification and buffering, the refrigerant flows at a stable pressure and rate to the expansion valve.
