Answer :
Final answer:
The correct answer to the fuel delivery control question is Electronic Fuel Injection (EFI) systems, which use electronic controls for precise fuel delivery. This innovation has replaced traditional carbureted systems for improved efficiency. EFI systems significantly enhance the performance and emission standards of modern vehicles.
Explanation:
Understanding Fuel Delivery Systems
The ability to control fuel delivery electronically has revolutionized internal combustion engines, particularly in vehicles. Among the options provided, the correct one is EFI systems, or Electronic Fuel Injection systems.
Electronic Fuel Injection systems use sensors and computer-controlled actuators to optimize fuel delivery based on real-time data such as engine speed, temperature, and air intake. This is in contrast to carbureted systems, which use mechanical means to mix air and fuel without electronic control.
In EFI systems, fuel is delivered through a series of components that include pumps, injectors, and fuel rails, allowing for precise metering and improved efficiency. The advancement in EFI technology signifies a move towards enhanced performance and reduced emissions in modern engines.
