Implementation of an Engine Control Unit for Automotive Fuel Injection

The objective of the research project is to implement an engine control unit (ECU) that we acquired recently to an automotive engine test bench for the fuel injection control purpose. The engine system to be used is a Sunbird engine (port-fuel-injection gasoline engine) that UBC Mechanical Engineering has. The ECU is a MotoHawk microcontroller which determines the amount of fuel to be injected based on sensor measurements. To measure the air-to-fuel ratio in real time, a wide-band oxygen sensor will be installed before the three-way catalytic converter in the exhaust pipe. Both a simple PID controller and an advanced robust controller will be tested, and the closed-loop system performances will be compared over various operating conditions (engine speed and air flow). These controllers will be realized in Matlab/Simulink, and transferred to the ECU microcontroller.
