Fuel injectors can vary, but the goals of the system remain the same.
- Fuel efficiency
- Emission performance
- Reliability, good drivability and smooth operation
- Diagnostic ability
Modern digital electronic fuel injection systems optimize these goals more effectively and consistently than previous systems and have been able to better atomize the fuel.
The fuel injection ensures a smoother throttle response, fast gas reaction times, an easier cold start, an accurate setting of the fuel taking into account changes in ambient temperatures and air pressure, and a more stable idling with the main aim of reducing vehicle emissions.
When the injectors are clean, engine performance is maintained and component-related fouling errors and breakdowns are reduced, emissions levels are met and fuel efficiency is increased.
