Control and measurement systems for spark ignition rotary engine
Abstract To precisely control and measure the performance of a single-rotor spark ignition rotary engine, a control system and measurement system were developed. A redundant design for hardware and software of sensors was applied. A symmetrical layout formed by two crankshaft position sensors was used to generate square wave signals that were complementary and inputted into the electric control unit as the crankshaft position reference. The corresponding software timing strategy and fault diagnosis were designed. Based on a simulation test and engine bench test, the electric control system shows a reasonable control effect, and the engine performance parameters including output torque, intake air flow and pressure, fuel and oil consumption, cooling air and coolant flow, and excess air ratio indicate that the engine control system and measurement system can operate smoothly.
