Abstract
A method and system for a hybrid opposed piston engine with dynamic controlling of the combustion volume and power output is provided. The method includes using a control system to control a phasing of opposed pistons for achieving a desired combustion volume during a combustion cycle. The control system can control an activation of an ignition of the hybrid opposed piston engine, such as to activate the ignition when a desired condition is present in the combustion chamber. Various embodiments of the hybrid opposed piston engine are further provided.
Claims20
A hybrid opposed piston engine, comprising:
- a cylindrical chamber;
- first and second pistons slidably disposed in the cylindrical chamber, surfaces of the first and second pistons and walls of the cylindrical chamber defining an internal combustion volume;
- at least one port in the cylindrical chamber to allow air and fuel into and exhaust gas out of the internal combustion volume;
- a first electrical component controlling a first crankshaft coupled to the first piston, the first electrical component controlling the first crankshaft to control a position of the first piston within the cylindrical chamber;
- a second electrical component controlling a second crankshaft coupled to the second piston, the second electrical component controlling the second crankshaft to control a position of the second piston within the cylindrical chamber;
- a control system including a volume scheduling control feature for dynamically controlling a position of the first and second pistons for achieving a net desired internal combustion volume during a combustion cycle.
A method of a hybrid opposed piston engine, comprising:
- receiving, at a control system of the hybrid opposed piston engine, sensed data associated with a first piston and a second piston;
- determining, by the control system and as a result of the received sensed data, a difference between an expected combustion volume during a combustion cycle and a measured combustion volume during the combustion cycle;
- and
- controlling, by the control system and as a result of the determined difference, a movement of the first piston and the second piston to achieve the desired combustion volume during the combustion cycle in real-time.
A method of a hybrid opposed piston engine, comprising:
- receiving, at a control system of the hybrid opposed piston engine, sensed data associated with a first piston and a second piston;
- determining, by the control system and as a result of the received sensed data, a position and a direction of movement of the first piston and the second piston;
- and
- controlling, by the control system and as a result of the determined position and direction of movement of the first piston and the second piston, an activation timing of an ignition for causing combustion in the combustion chamber.
