AI Technical Summary
Existing free piston compression ignition power generation devices face challenges when using low-carbon, low-activity fuels, including difficulties in achieving reliable ignition and stable combustion of low-activity main fuels under varying operating conditions, a lack of precise control over the supply and mixing modes of high-activity ignition fuels, and a lack of effective closed-loop regulation of the dynamic coordination between piston movement and the combustion process.
The design incorporates a free piston compression ignition power generation device with pre-combustion chamber ignition and composite regulation. By adding an independent pre-combustion chamber and a high-activity ignition fuel gas supply pipeline to the main combustion chamber, combined with an adjustable rebound chamber, electromagnetic drive and linear power generation unit and intelligent controller, the device achieves precise and controllable supply of high-activity ignition fuel and dynamic and coordinated regulation of the combustion process.
It achieves reliable ignition and stable combustion of low-activity fuels under varying operating conditions, precise and controllable supply of high-activity fuels, and dynamic coordinated adjustment of piston movement and combustion process, thereby improving the controllability and efficiency of the unit's operation.
