Abstract
Disclosed is an internal-combustion engine waste heat recovery and comprehensive utilization system which comprises a hydraulic motor (pump), a gas-liquid energy conversion cylinder, a gas path control valve, an operating tank, a high pressure tank, a condenser, an evaporator, a throttle, an ejector, an accumulator, a liquid path control valve and an oil tank; when the automobile runs normally, the gas path control valve and the liquid path control valve are opened to enable the gas in the operating tank to alternately enter the left and right sides of the gas-liquid energy conversion oil cylinder to realize the plunger reciprocating motions; the continuously-outputted high pressure liquid drives the motor to operate; the power outputted from the gear meshing of the motor gear and the gear of the transmission and the internal-combustion engine drive the automobile to run. When the automobile has smaller work load or is in the deceleration brake state, the motor turns into a pump; the internal-combustion engine adopts the extra energy to drive the pump to rotate, so as to generate the high pressure oil to drive the plunger to have reciprocating motions; a liquid exhaust electromagnetic valve and a liquid supplement electromagnetic valve can be opened to discharge the liquid in the condenser into the evaporator; then the liquid is sucked into the gas-liquid conversion cylinder to be compressed into the high pressure tank as the preparation for the next operation.
Description
Technical field
The invention belongs to that vapour rubs and the accessory technical field.
Background technique
Since Otto invention four-stroke reciprocating IC engine, the every field of the piston IC engine science that is applied to more and more widely, but the efficient of internal-combustion engine not high be that people wish the problem that solves always.Tracing it to its cause, is that its complementary energy all loses with the form of cooling and exhaust because the heat energy that fuel combustion produces during internal combustion engine has only 1/3 to change into effective merit; When automobile low speed was exercised, the energy that loses with cooling and exhaust form reached the heat energy of fuel combustion generation more than 90%; And automobile is in when braking, the kinetic energy that automobile has with friction type by consuming in vain.
The purpose of this invention is to provide a kind of afterheat of IC engine that can reclaim car brakeing and part exhaust and cooling energy reclaims and utilization system; To reach energy-conservation and the environmental protection purpose.
Summary of the invention
The present invention can change oil cylinder, gas path control valve, work jar, pressure pan, condenser, vaporizer, throttle valve, sparger, accumulator, liquid road control valve, fuel tank by oil hydraulic motor (pump), gas-liquid and form.The jar of wherein working is made tubular placing in the I. C. engine exhaust road, and the gas that heats wherein in order to the absorption heat of exhaust makes its pressure liter, to improve its capacity for work; Throttle valve is used to control the speed that gas-liquid can be changed oil cylinder output oil.Motor (pump) adopts variable displacement, by gear on it and the gear engagement on the speed changer, links together with car transmissions.Gas-liquid can be changed oil cylinder and be used for realizing that the pressure of gas can change mutually with the pressure of liquid, realizes the pressure of gas can form be discharged with the pressure of liquid, and the big position of mid diameter is used to feed gas in the cylinder, and the position that diameter is little is used to feed liquid; Accumulator is used for stablizing oil pressure and a small amount of hydraulic pressure energy of storage.Gas path control valve is used for the gas of Control work jar and alternately enters gas-liquid and can change oil cylinder left side and the to-and-fro motion of right side realization plunger, and exports highly pressurised liquid continuously; Also can be implemented in gas-liquid can change the little position of cylinder diameter when feeding highly pressurised liquid continuous liquid with in the vaporizer be pressed into pressure pan.Liquid road control valve is used for controlling gas-liquid can change communicating with motor that oil cylinder left end and right-hand member replace, makes gas-liquid can change the motor that enters that high pressure oil that oil cylinder left end and right-hand member produce can replace.The condenser sparger is used to utilize the gas that is discharged into condenser after the work done to come gas in the injection vaporizer, reduces thereby make liquid in the vaporizer evaporate endothermic temperature rapidly, and this cryogenic liquide can be used to refrigeration in the automobile.
Working principle: open throttle valve during automobile normal running, gas path control valve and liquid road control valve, the heat of liquid by cooling liquid and outlet pipe waste gas in radiator heat exchanger and the work jar absorption radiator in the pressure pan become alternately enter gas-liquid behind the pressurized gas and can change oil cylinder left side and the to-and-fro motion of right side realization plunger, and export the high pressure liquid drives motor operations continuously (when coolant temperature in the winter radiator heat is low, can open the radiator heat exchanger solenoid valve makes liquid directly enter the work jar without radiator heat exchanger), motor drives automobile running by the external outputting power of the gear engagement on gear and the speed changer with internal-combustion engine.The gas that is discharged into condenser after the work done simultaneously sprays at a high speed by sparger, comes the gas in the injection vaporizer, thereby rapid evaporation of liquid and endothermic temperature in the vaporizer are reduced; This cryogenic liquide can be used to refrigeration in the automobile.And the heat that the condensation of gas in the condenser produces in the winter time gas can be used to heating body in the automobile.
During less or retarding braking, motor is converted into pump,, produces high pressure oil and promotes the plunger to-and-fro motion with its rotation of energy drives more than needed with internal-combustion engine when the automobile working load; Can open draining solenoid valve and the fluid infusion solenoid valve enters vaporizer with the liquid in the condenser, suck gas-liquid by vaporizer again and can change oil cylinder and be pressed into pressure pan; For following task is prepared.
