1.	Which type of shape is provided on the plunger so that the quantity of fuel injected can be controlled?(a) Helix(b) Circle(c) Elliptical(d) RectangularThe question was posed to me by my college director while I was bunking the class.My query is from Fuel Injection Pump in division Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» The correct answer is (a) Helix To EXPLAIN I would say: The plunged contains a helix at its upper end which serves to control the quantity of FUEL to be injected. As the helix UNCOVERS the spill port, the fuel escapes through the VERTICAL SLOT in the plunger and spill port and pressure are released, shutting the valve down on its seat.
