Project GoalProject Goal☺Implementation of new

generation gasoline engine

control system based on FPGA.

☺The system will be able to

control engine in real time.

☺The system will work based on information that it gets from varied sensors .

SpecificationsSpecifications

☺ Receive data from engine sensors

and act accordingly.

☺ Send control signals to

the injectors and the plugs.

InputsInputsSensors:

☺ Mass airflow sensor (8 bits/value: 0-5v).

☺ Oxygen sensor (8 bits/value: 2.4-4v).

☺ Throttle position sensor (8 bits/value: 0-5v).

☺ Coolant temperature sensor (8 bits/value: 0-5v).

☺ Manifold absolute pressure sensor (8 bits/value:0-5v).

☺ Crank positioning sensor (1 bits/value: 0,1).

☺ Distributor sensor (1 bits/value: 0,1).

OutputsOutputs

☺Control signal to the injector, includes : - Time of starting the pulse (4 bits / value:

0,1). - Pulse width (1 bits / value: 0,1).

☺Control signal to the plugs, includes : -Time of giving the spark (1 bits / value:

0,1).

ScheduleSchedule1-8/12: Setting the graphs of the input

(sensors) signals and the output signals.

Modeling the input sensors.9-16/12: Studying LabView graphical

programming (basic level).17-24/12: Setting the lookup tables for the

sensors and continue studying LabView.
