Answer :
Final answer:
A common rail fuel injection system in Diesel engines delivers fuel to each injector individually. This system includes a rail carrying pressurized fuel connected to each fuel injector which is electronically controlled. This design ensures an efficient and complete combustion process.
Explanation:
The characteristic of a common rail fuel injection system in Diesel engines among the options provided is: They deliver fuel to each injector individually. A common rail fuel injection system typically includes a rail that's connected to each fuel injector, and the rail carries pressurized fuel. Traditional fuel system uses Mechanical injectors whereas in a common rail system, the injectors are electronically controlled. The pressurized fuel is sent to each cylinder, in the exact quantity and at the correct time, ensuring an efficient and complete combustion process. The complexity lies in maintaining high pressures, precise control over fuel delivery, and timing.
