Characterization Design of Gasoline engine control system based on FPGA Characterization Presented By: Sameh Damuni Sameh Damuni Firas Khair Firas Khair Instructor: Moni Orbach Moni Orbach 28/11/06

Project 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.

Specifications ☺ Receive data from engine sensors and act accordingly. ☺ Send control signals to the injectors and the plugs.

Inputs Sensors: ☺ 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).

Outputs ☺ 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).

Feedback Oxygen Throttle position Mass airflow Coolant temperature Manifold absolute pressure Crank positioning Distributor ECU Engine sensors
