A mechanic inspects the fuel injection system in a modern car engine.

Definition

Noun: A fuel injection system is a mechanical system designed to deliver atomized fuel directly into the cylinders of an internal combustion engine. This method precisely controls the amount and timing of fuel delivery, improving efficiency and performance while eliminating the need for a carburetor.

Usage

The term "fuel injection system" is used to describe the specific assembly of components (e.g., injectors, fuel pump, electronic control unit) that performs this function in modern vehicles and machinery. - It functions as the subject or object in a sentence. - It is often discussed in contexts of automotive engineering, mechanics, and vehicle performance.

Examples
  • The mechanic diagnosed a fault in the car's fuel injection system.
  • Modern fuel injection systems are controlled by sophisticated computer software.
  • Replacing the carburetor with a fuel injection system significantly improved the engine's fuel economy.
Advanced Usage
  • Direct fuel injection system: A more advanced type where fuel is injected directly into the combustion chamber of each cylinder, rather than the intake port, for greater precision and efficiency.
  • Electronic fuel injection (EFI) system: A common type where an electronic control unit (ECU) manages the injection process based on sensor data.
