Abstract
The utility model relates to an energy recovery and pressurizing device of an internal combustion engine, consisting of a hydraulic motor (pump), a gas-liquid energy converting oil cylinder, a gas circuit control valve, a working tank, a high-pressure tank, a low-pressure tank, an energy recovery tank, an energy accumulator, a liquid circuit control valve, an intake manifold, an ejector, an inlet manifold, a low-pressure tank air supply ejector and an energy recovery tank ejector. The utility model has the operating principle as follows: when an automobile travels, the quantity of heat of the exhaust is absorbed by the gas in a high-pressure gas storing tank through the working tank, the temperature of the gas raises, and the gas enters the gas-liquid energy converting oil cylinder to push a plunger piston to make reciprocating motion to output high-pressure liquid so as to drive the hydraulic motor to work; gears and gears on an intermediate shaft of a speed changer which are meshed and the internal combustion engine drive the automobile to run; the gas after doing work is discharged into the low-pressure tank and the energy recovery tank. When the automobile accelerates, the ejector is opened to eject the gas in the low-pressure gas storing tank to the inlet manifold to raise the air inlet pressure and increase the air inlet quantity so as to improve the power. When the automobile decelerates and brakes, the hydraulic motor is hauled reversely to rotate by the running automobile, the motor functions as a pump to generate high-pressure oil to push the plunger piston to make reciprocating motion, and the gas in the energy recovery tank is pressed into the high-pressure tank.
Description
Technical field
The utility model belongs to that vapour rubs and the accessory technical field.
Background technology
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 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 at glancing impact, the kinetic energy that automobile has with friction type by consuming in vain.
The utility model content
The purpose of this utility model provides a kind of combustion engine energy recovery and pressurizer that can reclaim car brakeing and part exhaust energy.When this device can also be worked as car acceleration, the gas blowout in the low pressure gasholder is mapped to the inlet manifold; Make intake pressure raise, strengthen suction quantity, and improve power.To reach energy-conservation and the environmental protection purpose.
The utility model by HM Hydraulic Motor (pump), gas-liquid can change oil cylinder, gas path control valve, work jar control cock, work jar, bomb, low pressure jar, bomb control cock, low pressure jar control cock, governor valve, eductor, energy storage, liquid road control cock, fuel tank is formed.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; Governor valve is used to control gas-liquid can change the defeated oil-out speed of oil cylinder.Motor (pump) adopts variable displacement, interrelates by the gear car transmissions on it.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, to realize the pressure energy form stored energy of energy with gas, and can form release energy with the pressure of liquid, 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; Energy storage 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 right side realization plunger crank motion, 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 gas with in the low pressure jar be pressed into bomb.Liquid road control cock 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 energy recovery jar is located between low pressure gasholder and the high pressure tank, establishes the energy recovery irrigation emitter between energy recovery jar and the low pressure jar; Be used for that the initial stage after the work done is discharged gas-liquid and can change oil cylinder part high pressure gas storage.Eductor is used for gas by the low pressure jar and comes gas in the injection inlet manifold, thereby the gaseous tension that enters in the induction maniflod is raise, and reaches the supercharging purpose.The exhaust that low pressure jar tonifying Qi eductor is used to utilize gas-liquid can change oil cylinder comes injection air admission low pressure jar, the gas of emitting with compensation.
Principle of work: open work jar control cock, low pressure jar control cock, gas path control valve and liquid road control cock during automobile normal running and make the gas of work jar alternately enter gas-liquid to change oil cylinder left side and right side realization plunger crank motion, and export the high pressure liquid drives motor operations continuously, by the external outputting power of the gear mesh on gear and the transmission countershaft, drive running car with combustion engine.Gas in the high pressure tank constantly adds to the work jar by check valve and governor valve simultaneously, and heat absorption pressure raises and presses in the work jar; The initial stage discharges gas-liquid and can change the part high pressure gas of oil cylinder and be pressed into the energy recovery tank stores by the energy recovery irrigation emitter after the work done.When being reduced to, can not export and automobile when still needing big power the gaseous tension in the bomb, can open supercharger control valve, make gas in the low pressure jar from gush out at a high speed gas in the injection inlet manifold of eductor, the gaseous tension that enters in the inlet manifold is raise, improve the power of combustion engine by supercharging.
When the automobile low speed driving, can close combustion engine and can drive running car by the hydraulic pressure that energy saver produces.When the automobile workload hour, motor is converted into pump,, produces high pressure oil and promotes the plunger crank motion with its rotation of energy drives more than needed with combustion engine, and the gas in the energy recovery jar is pressed into bomb, for task is down prepared.
During brake snub, the vehicle that motor is travelled is counter to drag rotation, and motor has become pump, produces high pressure oil and promotes the plunger crank motion, opens energy recovery jar control cock.Gas in the energy recovery jar is pressed into high pressure tank, stores energy to bomb.
