Study on Electrohydraulic Exhaust Valve of Single Piston Hydraulic Free-Piston Engine
This paper investigates the electrohydraulic exhaust valve of a single piston hydraulic free-piston diesel engine, which is intended to be a power supply for hydraulic propulsion systems. Double pulse signals of release solenoid valve are designed to eliminate the impacts of electrohydraulic exhaust valve seating. The control strategy of abnormal operation prediction is presented to protect the exhaust valve from collision. The experiments indicate that the soft seating of the exhaust valve can be achieved and the exhaust valve collision can be avoided utterly.
