Latest Patents

Zerull's notable patent is a "Free Piston Engine Control System". This advanced control system for a variable stroke free piston engine sets ignition timing based on measured piston velocity. The velocity proportional ignition system aids in starting the engine by providing spark advance on a stroke-by-stroke basis. Furthermore, the system seamlessly transitions to a piston position-based ignition strategy when the engine reaches a steady state. Fuel injection occurs at either the piston dead point or is adjusted according to piston position, with suppression of fuel injection during cycles where the ports are not uncovered. Additionally, the control system can regulate the compression ratio based on piston position or knock sensor data. Zerull's design incorporates a hybrid digital-analog system, featuring a microprocessor for optimized performance.
