N2 - A prototype rotary valve engine has been built from a conventional single piston generator. In this study, an engine control unit, ECU, is designed, tested and implemented for the purpose of carrying out the primary engine functions of sparking, fuelling and valve events control. The rotary valve engine has no camshaft, therefore, only a crankshaft (optical) sensor is required. The controller has also the advantage of turning the engine in either direction, removing the need for a reverse gear. Full control over valve events, together with crank motion independent sparking, removes the need for a throttle valve and a mechanical starter. With the valve turning freely, no feedback sensing is necessary. The proposed ECU has been designed, successfully tested and implemented on ALTERA's UP1 prototyping board. The FPGA programmable device used is the EPM7064SLC44-5.
