Device for recovering complementary energy of internal combustion engine

Abstract

The invention relates to a device for recovering complementary energy of an internal combustion engine, which comprises a pump-motor, a gas-liquid energy conversion oil cylinder, a reversing valve, a high-pressure tank, a low-pressure tank, a heat exchanger and the like. The device for recovering the complementary energy of the internal combustion engine has the working principle that a flow control valve is used for controlling the working medium of the high-pressure tank to enter the heat exchanger to absorb the heat of the exhaust gas of an exhaust pipe to become high-pressure gas; under the control of the reversing valve, the high-pressure gas alternately enters rod gas cavities respectively arranged at the left side and the right side of the gas-liquid energy conversion oil cylinder, and generated pushing forces push pistons to do reciprocating motions; the gas after applying work in the rod gas cavities enters rodless gas cavities to continue to expand to apply work, and the pushing forces generated by the rodless gas cavities and the pushing forces generated by the rod gas cavities jointly push the pistons to do the reciprocating motions; high-pressure liquid is output to drive the pump-motor to work; and the motor externally outputs power through meshing a gear with a gear on a transmission to drive an automobile to run together with the internal combustion engine.

Description

technical field [0001] The invention belongs to the technical field of automobiles and motorcycles and accessories. Background technique [0002] Since Otto invented the four-stroke reciprocating piston internal combustion engine, the piston internal combustion engine has been more and more widely used in various fields of science, but the low efficiency of the internal combustion engine has always been a problem that people hope to solve. The reason is that only 1 / 3 of the heat energy generated by fuel combustion when the internal combustion engine is working is converted into effective work, and the rest of the energy is lost in the form of cooling and exhaust; and when the car is braking, the kinetic energy of the car is in the form of friction Wasted in vain. [0003] The object of the present invention is to provide a residual energy recovery device of an internal combustion engine capable of recovering vehicle braking and partial exhaust and cooling energy; to achieve...
