Which of the following does not depend on the fuel quantity injected?(

1.	Which of the following does not depend on the fuel quantity injected?(a) System pressure(b) Duration of injection(c) Size and shape of the nozzle(d) Alternator speedThe question was posed to me by my school principal while I was bunking the class.I need to ask this question from Modern Common Rail Fuel Injection System in chapter Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» The correct option is (d) Alternator speed To explain I would say: The fuel is injected in the engine COMBUSTION CHAMBER by the injection nozzle of an injector controlled by a solenoid-operated valve. The injector receives its operation signal from ECU. The system PRESSURE, the duration of injection, and the size of the nozzle determine the fuel quantity injected.
