1.	Which among the following is defined as the amount of time the injector stays open and also determines the amount of fuel supplied to the engine?(a) Flat spot(b) Pulse radiation(c) Pulse width(d) Dark pulseThis question was posed to me in an interview for job.Enquiry is from Petrol Injection in section Petrol Engine Fuel Supply System of Automotive Engine Design
Answer» The correct OPTION is (c) Pulse width The best EXPLANATION: The amount of time the INJECTOR stays open determines the amount of FUEL supplied to the engine it is called the pulse width. This time duration and the amount of fuel flowing into the combustion CHAMBER is controlled by the ECU.
