51.	How is the fuel injection time controlled in a distributor type fuel injection pump?(a) Internal-cam ring(b) Crankshaft(c) Motor(d) RotorThis question was posed to me in an interview for job.Query is from Fuel Injection Pump topic in chapter Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» The CORRECT ANSWER is (a) Internal-cam ring The best I can explain: The fuel injection timing in a distributor type of fuel injection PUMP is controlled by rotating the internal-cam ring. As the ENGINE speed increases, the fuel feed pump delivery pressure increases.

52.	To which of the following the number of radial holes equal in a distributor type fuel injection pump?(a) To the float valve(b) To the number of the engine cylinder(c) To the number of gears(d) To the number of governorsThe question was posed to me in exam.Asked question is from Fuel Injection Pump topic in section Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» The correct OPTION is (b) To the number of the ENGINE cylinder Explanation: In a distributor TYPE FUEL injection pump there is a set of radial holes (suction port) EQUAL to the number of the engine cylinder. Similarly, the outer sleeve also has a set of an equal number of holes (delivery ports ) which are offset from the suction ports.

53.	Which of the following helps in the fuel distribution in a distributor type fuel injection pump?(a) Crankshaft(b) Rocker arms(c) Rotor(d) MotorThis question was addressed to me during an online interview.My question comes from Fuel Injection Pump topic in division Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» Correct OPTION is (c) Rotor The explanation: In a distributor type of fuel INJECTION pump the fuel is distributed to each cylinder using a rotor. The rotor has a central LONGITUDINAL passage and SET of radial holes which DEPENDS on the engine configuration.
