Abstract :
Two engine subsystems, a digital engine speed display and an advance ignition system, are simulated and discussed to provide the understanding and insight necessary to design a microcontroller-based electronic control system for a four stroke and single cylinder engine. A DC motor whose speed is adjusted by a voltage transformer and numerated by a photo sensor, 8751 H microcontroller, and digital readout is used as an engine. A lookup table for the nonlinear relation between the engine speed and the advance ignition angle is stored in an EPROM. A timing light is used to identify the advanced ignition angles of the spark plug. This simulation shows that some mechanical hardware can be replaced by electronic components to make automobile engines more efficient and inexpensive
