1. 1 Gasoline engine control system final presentation Winter 2007 Presented By: Sameh Damuni Sameh Damuni Firas Khair Firas Khair Instructor: Moni Orbach Moni Orbach 27/6/2007

2. 2 Project Goal Implementation of new generation gasoline engine control system. Implementation of new generation gasoline engine control system. The system will be able to control engine in real time. The system will be able to control engine in real time. The system will work based on information that it gets from varied sensors. The system will work based on information that it gets from varied sensors.

3. 3 Block diagram for the system

4. 4 Engine transmission functions 0< Pedal <100 (%) 0< Pedal <100 (%) Throttle position= 0.65*(pedal) Throttle position= 0.65*(pedal) Coolant temperature = 1.35*(pedal) Coolant temperature = 1.35*(pedal) Mass airflow = 1.66166*(pedal)+0.5 Mass airflow = 1.66166*(pedal)+0.5 Manifold pressure = 20+(113/65)*(pedal) Manifold pressure = 20+(113/65)*(pedal) RPM = 44.24*(Manifold pressure)115.2+ RPM = 44.24*(Manifold pressure)115.2+
