1.	Which of the following increases concerning the metering valve when the accelerator pedal is pressed?(a) Temperature(b) Pressure(c) Area(d) EnthalpyI got this question in an interview.This key question is from Fuel Injection Pump topic in section Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» Correct CHOICE is (c) Area Easiest EXPLANATION: A metering VALVE controlled by the governor REGULATES the amount of fuel entering the ROTOR. Pressing the accelerator pedal increases the area of the metering port allowing more fuel to enter the rotor, thereby increasing the engine speed.
