Technician a says that injector nozzles are either opened by the high-pressure pulse from a distributor pump or electrically by the computer on a common rail design. technician b says that indirect injection (idi) occurs directly into the combustion chamber. who is correct? a. technician a b. neither technician a nor b c. technician b d. both technicians a and b

Answer

A.Technician A is correct

Explanation

The injector nozzle can be opened electrically by the computer on a common rail design.

High pressure of the fuel in the pressure chamber pushes the needle valve up which compresses the return spring in the needle valve thus opening the valve.
