The corrective injection duration is calculated from the engine condition detected by various sensors.Group of answer choicesTrueFalse

The basic injection duration is determined by the accelerator opening angle and the engine speed.Group of answer choicesTrueFalse

Actual injection duration = Basic injection duration + Corrective injection durationGroup of answer choicesTrueFalse

a 4-cylinder car gets 14.5km/l of gasoline from a gasoline port-type EFI system, and operates at 3000rpm (on average) at an average vehicle speed of 100kph. if the injectors gasoline flow rate (open) is 5g/sec, what is the typical injection duration (ms)? assume one injection per cylinder per cycle.

The amount of fuel delivered by the injector depends upon thea.All the above factorsb.Size of injector nozzlec.Length of time the injector is opend.Pressure pushing fuel through the injector
