Fuel Injector Mechanism: Precise Fuel Delivery System Using High-Pressure Nozzle and Electronic Cont

Подробнее о видео

Detailed Description:

This animation showcases the working mechanism of a fuel injector, a vital component in modern internal combustion engines. Fuel injectors are responsible for delivering the right amount of fuel into the combustion chamber at the right time and in the right spray pattern, ensuring optimal air-fuel mixture for efficient combustion.

The process begins when the engine control unit (ECU) sends an electrical signal to the fuel injector. This activates an electromagnetic solenoid inside the injector, lifting a nozzle valve and allowing pressurized fuel (usually between 40–200 bar) to spray into the intake manifold or directly into the combustion chamber. The spray atomizes the fuel, breaking it into tiny droplets for faster and cleaner combustion.

This precise fuel injection helps achieve:

Better fuel efficiency

Lower emissions

Improved engine performance

Faster throttle response


There are various types of injectors such as port fuel injectors, direct fuel injectors, and common rail systems, depending on engine design and performance needs.

🔧 This animated video is ideal for mechanical engineering students, automobile enthusiasts, and 3D animation lovers interested in how modern engine components work.
