Description
Technical field
The utility model relates to the internal-combustion engine booster auxiliary device, relates in particular to a kind of pressurized machine cooling and lubricating device when internal-combustion engine is anxious shuts down.
Background technique
Along with national Abgasgesetz is more and more tighter, the use of pressurized machine on internal-combustion engine also more and more widely, it is greatly improved aspect the engine performance improving.The pressurized machine that uses on the present stage motor all is to rely on oil pump pump machine oil that it is lubricated cooling.When the motor proper functioning, machine oil is pumped by oil pump, through pressurized machine, has taken away a part of heat when playing lubrication again, gets back to oil sump through the pressurized machine return tube then.After pressurized machine starts at ordinary times, before the orderly closedown, all need let engine idle move a few minutes earlier, to reach the cooling and lubricating effect.But also there are some defectives in such layout: the one, and when internal-combustion engine is shut down suddenly when full load runs up, pressurized machine and oil pump also quit work thereupon; At this moment because the disappearance of machine oil; Make a large amount of heats in the pressurized machine still be present in the machine and can't take away, thereby make pressurized machine bear Gao Re at short notice and damage, the 2nd, when proper functioning; Owing to all need idling work a period of time before each high speed stop; So not only do some idle works, also wasted fuel oil, got off also to be unfavorable for engine energy-saving and environmental protection for a long time.For this reason, existing technology is connected in parallel on the delay lubrication protection device in the oil circuit through increase, has avoided the problems referred to above effectively.Like Chinese patent notification number: CN201437736U, the day for announcing: on April 14th, 2010, model utility title: " pressurized machine postpones the lubrication protection device "; It discloses a kind of oil pump that is connected in parallel on and has supplied the protective gear in the oil circuit of engine lubrication to pressurized machine simultaneously; This protective gear comprises oil cylinder, one-way valve,, solenoid valve and throttle valve, said oil cylinder is when the motor proper functioning; Storage full lubricant oil in oil cylinder one chamber rises and holds functional oil.Treat engine shutdown, the electronic control unit EDU of motor obtains the engine shutdown signal and opens solenoid valve immediately, and pressurized air gets into another chamber of oil cylinder, promotes piston through suction tude, and storage full lubricant oil in a chamber is extruded, and offers pressurized machine through oil pipe.Though this device of existing technology can solve the unexpected defective that the back internal-combustion engine still needs work a period of time of shutting down; But; Existing technology exists the part of its device many simultaneously, and all is hydraulic element, and its deficiency is: 1, behind the long-play because the influence of oil impregnate; Can cause getting into the low on fuel of the oil cylinder of storing oil pocket, have the hidden danger that causes the pressurized machine protection to be lost efficacy; 2, when oil pressure was not high, piston motion was not in place, and actual oil storage space is dwindled, and also can reduce actual cooling effect.3, forming this device hydraulic parts has four, and not only electricity consumption also will be used gas, and element is many, and cost is high.
Summary of the invention
The purpose of the utility model is to overcome to have now to exist hydraulic element many; Oil impregnate not only causes the cooling and lubricating weak effect easily, also can produce deficiencies such as disabler; Provide a kind of simple in structure; Cost is low, and no oil impregnate can be implemented the device that cooling and lubricating is protected to pressurized machine reliably when the anxious shutdown of internal-combustion engine.
For realizing above-mentioned purpose; The technological scheme that the utility model adopts is: a kind of pressurized machine cooling and lubricating device; Comprise pressurized machine, storage battery, ECU, oil pump, oil sump, said oil pump is connected between oil sump and the pressurized machine filler opening, and the return tube of pressurized machine is connected with oil sump; On the described pressurized machine filler opening parallel connection electrically operated fuel pump; The oil outlet of electrically operated fuel pump is connected with the filler opening of pressurized machine through oil outlet tube, and the filler opening of electrically operated fuel pump is communicated with oil sump through oil inlet pipe, has lead to be connected with storage battery with ECU respectively on the electrically operated fuel pump.
Described storage battery is the car load storage battery.
Compared with prior art, the beneficial effect of the utility model is: 1. adopt electrically operated fuel pump to replace four hydraulic element of existing technology, do not have and leak, reliable performance has guaranteed that pressurized machine is not because of overheated impaired.2. simple in structure, cost is low, the high idle speed operating time when simultaneously also having reduced orderly closedown, thus playing the effect of fuel-economizing, in cycle motor life-cycle, can effectively economize on resources, amount to and save cost more than 5%.3. highly versatile, and can be widely used on existing various types of internal-combustion engines.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: pressurized machine 1, oil outlet tube 2, electrically operated fuel pump 3, storage battery 4, ECU5, oil pump 6, oil sump 7, oil inlet pipe 8.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further description, but be not restriction its protection domain.
Referring to Fig. 1; A kind of pressurized machine cooling and lubricating device of the utility model; Comprise pressurized machine 1, storage battery 4, ECU5, oil pump 6, oil sump 7, said oil pump 6 is connected between oil sump 7 and pressurized machine 1 filler opening, and the return tube of pressurized machine 1 is connected with oil sump 7; On described pressurized machine 1 filler opening parallel connection electrically operated fuel pump 3; The oil outlet of electrically operated fuel pump 3 is connected with the filler opening of pressurized machine 1 through oil outlet tube 2, and the filler opening of electrically operated fuel pump 3 is communicated with oil sump 7 through oil inlet pipe 8, has lead to be connected with storage battery 4 with ECU5 respectively on the electrically operated fuel pump 3.
Described storage battery 4 is the car load storage battery.
Behind the internal combustion engine start, oil pump 6 beginning fuel feeding, this moment, electrically operated fuel pump 3 was not worked, machine oil arrives pressurized machines 1 by oil sump 7 through oil pump 6, pressurized machine 1 is carried out cooling and lubricating after, get back to oil sump 7 again through oil outlet tube 2.
When the internal-combustion engine emergency shutdown, oil pump 6 also quits work, simultaneously; After electronic control unit ECU5 receives the engine shutdown signal, electrically operated fuel pump 3 and storage battery 4 are connected, electrically operated fuel pump 3 begins pressurized machine 1 is assisted oil transportation; Continue 3～5 minutes, thereby guarantee that pressurized machine 1 after oil pump 6 quits work, still has the input of lubricant oil; And keep a period of time, until pressurized machine 1 cooling, play the effect of protection pressurized machine 1.
When the internal-combustion engine orderly closedown, set the engine shutdown signal and send in advance to electronic control unit ECU5, ECU5 makes electrically operated fuel pump 3 and storage battery 4 connect at once, and electrically operated fuel pump 3 is worked in advance.Kill engine then and oil pump 6, reduce motor high idle speed running time, even engine stop working like this, also having guaranteed has enough lubricant oil to cool off in the pressurized machine 1, thereby has saved fuel, reaches oil-saving effect.
The utility model has just substituted existing technology with an electrically operated fuel pump 3 and has comprised oil cylinder, one-way valve,, four hydraulic element such as solenoid valve and throttle valve, also need not to use gas, element is few, cost is low, and is simple.
