Fuel injection explained | Mechanical Engineering

In airplanes with a manual mixture control, pilots modulate the fuel to air ratio entering the cylinder. This control is generally red in color and located next to the throttle. When the control is pushed forward it enriches the mixture, meaning the amount of fuel in the mix is increased. When the control is pulled back, it leans the mixture, and the amount of fuel is reduced. The main reason pilots adjust the mixture is to match the air pressure, since air pressure changes with altitude. At hig

Why have jet fuel tanks become so safe? Modern airliners from Boeing and Airbus are protected by advanced Fuel Tank Inerting Systems. These systems pump nitrogen into the tanks, removing oxygen so fuel vapors can’t ignite — a breakthrough in aviation safety. Born out of lessons from TWA Flight 800, this invisible safeguard makes explosions virtually impossible while jets operate. Silent, automatic, and vital — it’s one of aviation’s smartest safety upgrades. #avgeek #planespotting #Boeing #airbu
