6

Which diesel system supplies high-pressure diesel fuel to all of the injectors all of the time?

A) Distributor type fuel injection system B) Inline pump fuel injection system C) Common rail fuel injection system D) Rotary fuel injection system

Discuss

Answer & Solution

Answer: Option C

Solution:

The Common Rail Fuel Injection System stores diesel fuel at very high pressure in a common pipe called a rail, which continuously supplies fuel to all injectors.

In this system, high-pressure fuel is available to all injectors all the time, regardless of engine speed or injection timing requirements.

The injectors receive fuel from the common rail and electronically control when and how much fuel is injected into the engine cylinders.

This arrangement provides better fuel atomization, improved fuel efficiency, lower emissions, and more precise control of injection timing.

Other systems such as distributor, inline pump, and rotary fuel injection systems generate and distribute fuel differently and do not continuously maintain high-pressure fuel availability to all injectors simultaneously.

Therefore, Option C: Common rail fuel injection system is the correct answer.
