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. An electric solenoid connected to the injector is controlled by this computer and opens to pass the fuel into the injector pressure chamber. 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.

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.
