Abstract

A camless engine using rotary valves has been proposed before and found feasible. In this paper, a single controller doing the primary engine functions of sparking, fuelling and valve events control is proposed. With no camshaft, 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 controller has been designed, successfully compiled using ALTERA's MAX PLUS II design environment and programmed into an FPGA device, the EPM7064LC68-7.
