determining a first quantity of fuel to be delivered by the
fuel injector based on the first desired engine torque output and
the engine speed;
determining an injection pressure; and
determining a first amount of time for energizing the fuel
injector in order to deliver the first quantity of fuel based on
the injection pressure.
11. A system for controlling fuel delivery from a fuel
injector having an electronic control valve, the fuel injector
being in communication with a fuel rail, the system comprising:
a crankshaft sensor for sensing rotational speed of the
crankshaft;
a fuel pressure sensor for measuring fuel pressure in the
fuel rail;
a microprocessor in communication with the crankshaft
sensor, the fuel pressure sensor and the electronic control
valve, the microprocessor including instructions for determining
a first desired engine torque output, instructions for
determining engine speed based on the rotational speed of the
crankshaft, instructions for determining a first quantity of fuel
to be delivered by the fuel injector based on the first desired
engine torque output and the engine speed, instructions for
determining fuel pressure in the fuel rail using the fuel
pressure sensor, instructions for determining a first amount of
time for energizing the electronic control valve in order for the
fuel injector to deliver the first quantity of fuel based on the
fuel pressure and the first quantity of fuel, and instructions
for generating an output signal for the electronic control valve
corresponding to the first amount of time.
