How do fuel injectors work?
Fuel injectors are a vital component of your car’s engine, responsible for delivering the right amount of fuel to each cylinder. They work by spraying pressurized fuel into the combustion chamber at precisely timed intervals. This ensures optimal fuel-air mixture for efficient combustion and power generation.
The process begins with the opening of the injector valve, allowing pressurized fuel to flow through a tiny nozzle and form a fine mist. The electronic control unit (ECU) determines when and how long to open the injector based on various sensor inputs such as engine speed, throttle position, and oxygen levels in the exhaust.
Once injected into the combustion chamber, the fuel mixes with incoming air before being ignited by spark plugs. The resulting explosion forces pistons down, driving crankshafts that ultimately power your vehicle.
In modern engines, each cylinder has its own dedicated injector, enabling precise control over fuel delivery. This allows for better performance, improved efficiency, and reduced emissions compared to older carbureted systems.
