Rapid Prototyping an FPGA-based Engine Controller for a 600cc Super-Sport Motorcycle 2005-01-0067

Two main goals exist for prototype engine control systems. One goal is to research specific areas of engine control or behavior such as fuel delivery or exhaust emissions. Another goal is to prototype an engine controller for aftermarket applications or Original Equipment Manufacturer (OEM) production. In either case, engineers often face the challenge of creating a prototype controller for an already existing OEM engine with little or no knowledge of the control strategies embedded within the OEM controller. This paper will discuss an FPGA-based system used to map the behavior of an OEM controller as well as function as the prototype controller. The FPGA was used to track the angular position of the crankshaft and generate fuel and spark control signals synchronously to the rotation of the crankshaft, as well as to acquire analog and digital sensor data.
