dc.description.abstract | The objective of this research was to develop an engine control unit (ECU) for a four cylinder engine to be used in a Formula SAE racers. The ECU must provide effective fuel injection and spark ignition control and provide for easy adjustment by the user for engine tuning purposes. The controller was designed to operate using a speed-throttle fuel map, with acceleration enrich, meet and other fuel compensating factors. A paired double-tiring strategy was adapted to avoid the complications associated with sequential fuel injection. The ECU utilized a Motorola 68HC16 development board, as well as special injector and ignition driver circuits. The software was designed to be primarily interrupt driven, with a task manager to arbitrate among other tasks. A user interface program, which runs on a PC, allows the user to instantly alter operating parameters in the ECU during engine tuning and development. The controller was tested on a Yamaha YZF 600 motorcycle engine with a custom intake manifold and fuel injection system. The fuel and spark maps and other parameters were configured for this engine by using the user interface. Dynamometer testing verities that engine performance with this ECU meets design specifications. | en |
