Description
One. technical field:
The present invention relates to a kind of oil supply system of exhaust gas turbocharger that is used for providing machine oil to the exhaust-gas turbocharger of motor.In the startup and pass closed procedure of motor, oil supply system of exhaust gas turbocharger can in time be worked a period of time before engine start automatically, provide lubricated required machine oil to exhaust-gas turbocharger, make exhaust-gas turbocharger before running, can obtain lubricated required machine oil; Be in the time of the one section setting of in time working automatically again after shutting down each time at motor, in the time of this section setting, provide machine oil lubricated, that cooling is required to exhaust-gas turbocharger, make the exhaust-gas turbocharger rotor at engine stoping operation, when doing the inertia rotation behind the oil pump fuel cut-off, still obtain the machine oil of sustainable supply, guaranteeing needs lubricated and cooling, thereby prolong the working life of exhaust-gas turbocharger effectively.
Two. technical background:
Present exhaust gas turbocharge motor is because oil pump is synchronoused working with motor.So before engine start, oil pump is can not pump machine oil, this moment, exhaust-gas turbocharger was can the organic oil input.Behind engine start, oil pump and exhaust-gas turbocharger turn round simultaneously, because the machine oil that oil pump pumps will be by arriving the rotor bearing of exhaust-gas turbocharger behind the oil transport pipeline of certain-length; The rotor bearing of exhaust-gas turbocharger had turned round before machine oil arrives so, hear when arriving this section of bearing from the exhaust-gas turbocharger entry into service to machine oil, the rotor bearing of exhaust-gas turbocharger does not have machine oil to flow through, and the rotor bearing of exhaust-gas turbocharger of this moment had experienced the coasting process under one section inorganic oil supply status when last time, motor stopped, rotor bearing has been the state of place's insufficient lubrication, that is to say before machine oil arrives that during this period of time the rotor bearing of exhaust-gas turbocharger is to be in entry into service under the condition attitude of insufficient lubrication.
Because when motor moves, the rotary speed of rotator of exhaust-gas turbocharger is very high, when motor quits work, oil pump also quits work synchronously, and this moment, the rotor of exhaust-gas turbocharger still stops up to continuous decrescence speed from running up under action of inertia, that is to say stop pump oil from oil pump after, rotor to exhaust-gas turbocharger shuts down during this period of time, the rotor of exhaust-gas turbocharger is to be under the condition attitude of unlubricated and the required engine oil supplying of cooling to carry out coasting, at this moment, the wear extent of rotor bearing is maximum, and this also is that most exhaust-gas turbocharger damages the main cause that lost efficacy.
Three. summary of the invention:
Current exhaust gas turbocharge motor is after shutting down, and the rotor of its exhaust-gas turbocharger still can rotate a period of time under effect of inertia; Motor shuts down at the state of running up at once, the rotor of its exhaust-gas turbocharger has higher inertia rotating speed, thereby must the longer time of high speed rotating under the state of inorganic oil sustainable supply, this will make the wear extent of the rotor bearing of exhaust-gas turbocharger increase severely, and causes the life-span of exhaust-gas turbocharger to be reduced sharply.So all advise on the operating instruction of exhaust gas turbocharge motor, need before the engine shutdown can shut down after idle several minutes; Its purpose mainly is, make the rotor of exhaust-gas turbocharger can be under the state that the supply of lasting machine oil is arranged, with speed drop to engine idle the time after the corresponding rotating speeds again row close down motor, under the state of the inorganic oil supply of the rotor that makes exhaust-gas turbocharger after motor stops, rotate to the minimum inertia rotating speed and to stop, it is minimum to make the wear extent of rotor bearing reduce to, and can prolong the working life of exhaust-gas turbocharger to the greatest extent; Even operate like this, the rotor of exhaust-gas turbocharger still needs under the state of inorganic oil supply, rotates to from the minimum inertia rotating speed to stop.
One of shortcoming that current exhaust-gas turbocharger exists is: although motor was just closed down after idle several minutes, but the rotor of exhaust-gas turbocharger still needs under the state of the inorganic oil supply after motor stops to rotate to from the minimum inertia rotating speed and stops, the wear extent of rotor high-speed rotation when during this period of time, the wear extent of rotor bearing is still far above the organic oil supply status; But also being directed at the initial stage of exhaust-gas turbocharger at following task, rotor bearing is to be in the extremely state running down of insufficient lubrication.
Therefore in order to reduce the wear extent of rotor when inorganic oil is supplied to prolong the working life of exhaust-gas turbocharger, when closing down motor, all need just to be closed down motor after idle several minutes at every turn, this makes motor close at every turn all needs several minutes idling oil consumption of many wastes, and many number of discharges minute waste gas, this both had been unfavorable for environmental protection and energy-conservation social demand; Also hinder the automobile that uses the motor that exhaust-gas turbocharger is arranged to adopt no idling fuel-saving control pattern to carry out the fuel-economizing operation simultaneously.
For solving the problem of not having lasting machine oil supply when the exhaust-gas turbocharger rotor is in the inertia rotation behind engine shutdown, need idle several minutes meaningless oil consumption and toxic emission before the elimination engine shutdown, the technical solution used in the present invention is:
In the machine oil fuel feeding road of former exhaust-gas turbocharger, increase a system that supplies machine oil automatically to exhaust-gas turbocharger, that is: oil supply system of exhaust gas turbocharger, its working principle is:
After engine motor oil pressure switch closure each time, oil supply system of exhaust gas turbocharger quits work after the promptly in good time one artificial period of setting of automatically working automatically again, oil supply system of exhaust gas turbocharger uses electric oil pump to supply machine oil to exhaust-gas turbocharger when work.
When the engine motor oil pressure switch was in off state, oil supply system of exhaust gas turbocharger promptly quit work automatically.
Advantage of the present invention is:
1. engine start is preceding when the key switch is in the on position, the engine motor oil pressure switch is in the bonding state of closed conducting under the effect of inorganic oil pressure, at this moment, oil supply system of exhaust gas turbocharger uses electric oil pump to supply machine oil to exhaust-gas turbocharger, makes the bearing of the rotor in the exhaust-gas turbocharger obtain the machine oil supply before rotation.Behind engine start, under the effect of engine oil pressure, when the Oil pressure switch of motor was in the non-bonding state of disconnection, oil supply system of exhaust gas turbocharger promptly quit work automatically.
2. behind the engine stoping operation in the running, oil pump promptly quits work synchronously, the Oil pressure switch of motor is in closed conducting bonding state under the effect of inorganic oil pressure, at this moment, oil supply system of exhaust gas turbocharger uses electric oil pump to supply machine oil to exhaust-gas turbocharger, guaranteeing before rotor stops operating, the machine oil supply that the rotor bearing of exhaust-gas turbocharger obtains continuing to be being used for lubricated and cooling, and stops the work of electric oil pump behind set time automatically.
