Direct-action power generation system with speedup spring forced vibration

Abstract

The invention discloses a directly operated power generation system which directly utilizes the rectilinear motion of a reciprocating engine piston to drive coils or a magnet to generate electric current for power generation. During the period of non-expansion stroke, the motion of the piston is driven by utilizing a vibrating system and the electromagnetic force of the coils; in the system, the piston, power generation coils and a linking mechanism are connected with a coil spring. The piston and the coils connected with the piston are controlled by a balancing spring at the near end of the piston and an accelerating spring at the remote end of the piston by a stress board and a connecting rod and then a forced vibration system is formed. The system uses a method for adjusting the movement velocity of the piston in the last phase of the expansion stroke so as to realize the adjustment of the system frequency and also uses a method for adjusting the number of working cylinders and the air input capacity to carry out the power regulation; by utilizing that the system is characterized by no fixed top dead center and the easily adjustable compression ratio, a compression-ignition type ignition is adopted and the volume compression ratio can be adjusted according to the air inlet capacity so as to realize the comparatively high compression ratio within a wide working range, thereby improving the efficiency.
