A 2A-liter, four-cylinder engine is equipped with multipoint port fuel injection, having one injector per cylinder. The injectors are constant-flow devices, so the fuel flow rate into the engine is controlled by injection pulse duration. Maximum power is obtained at WOT when injection duration is continuous. At this condition, engine speed is 5800 RPM with stoichiometric gasoline and an inlet pressure of 101 kPa. At idle condition, the engine speed is 600 RPM with stoichiometric gasoline and an inlet pressure of 30 kPa. Volumetric efficiency can be considered 95% at all conditions. Calculate: (a) Fuel flow rate through an injector. [kg/sec] (b) Injection pulse duration in seconds at idle conditions. (c) Injection pulse duration in degrees of engine rotation at idle conditions.
