Abstract
This paper presents an engine management system to control a 4 stroke two cylinder motorcycle engine. At the heart of the system is a microcontroller based reference design engine control unit. This works together with a crank wheel sensor, throttle position sensor, oxygen sensor, barometric pressure sensor, injectors, ignition coils and fuel pump.
This system has the capability to detect engine position, sense throttle position, air temperature, control fuel injection timing and amount and control spark timing and dwell. It has the option to control idle with stepper motor and has close loop feedback of oxygen levels in the exhaust. Serial communication via KWP2000 is used for reprogramming of the controller and reading diagnostic codes.
The main goal of this system is to meet emission requirements and provide On Board Diagnostics (OBD) capability. This presentation will discuss the system's electronics including voltage regulators, smart drivers and IGBT. Fault protection and detection capabilities using the smart drivers will also be discussed.
