Abstract

The invention discloses a vibration control and energy recovery device and method for a free piston internal combustion engine generator. Electromagnetic energy recovery mechanisms are installed between engine cylinder covers at the two ends of the free piston internal combustion engine generator and an external mechanism. Each electromagnetic energy recovery mechanism comprises a rotor assembly and a stator assembly matched with the rotor assembly, and a spiral spring is arranged between the rotor assembly and the stator assembly; the rotor assembly is installed on an engine cylinder cover and provided with a permanent magnet, and the stator assembly is installed on the external mechanism and provided with a coil corresponding to the permanent magnet; and the coil is connected with a control system of the free piston internal combustion engine generator, the control system is used for controlling whether the coil is powered on or not and the magnitude of the input current, and vibration control and energy recovery are achieved based on the electromagnetic energy recovery mechanisms. The free piston internal combustion engine generator can solve the problem that the vibration intensity is too large when the free piston internal combustion engine generator is used as an automobile range extender, and the energy conversion efficiency of a system is improved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of vibration control and energy recovery, in particular to a vibration control and energy recovery device and method for a free-piston internal combustion generator. Background technique [0002] Energy application and conversion devices have always been a hot research field in scientific research. As a new type of energy conversion device, free piston internal combustion generator has the advantages of high volume power, adjustable compression ratio and convenient modular arrangement; it is very suitable for Future use of range extenders for hybrid vehicles. [0003] The free-piston internal-combustion generator is still in the stage of principle exploration. According to the current research results, when the free-piston internal-combustion generator with special structure is installed on the vehicle as a range extender, its own strong vibration and unique vibration characteristics will restrict its appli...
