Description
One. technical field:
The present invention relates to a kind of for providing the oil supply system of exhaust gas turbocharger of machine oil to the exhaust-gas turbocharger of motor.In the startup and closing process of motor, oil supply system of exhaust gas turbocharger can in time automatic operation a period of time before an engine is started, there is provided the machine oil needed for lubrication to exhaust-gas turbocharger, make exhaust-gas turbocharger can obtain machine oil needed for lubrication before running; Motor be in each time shut down after again in time automatic operation one section setting time, within the time of this section of setting, the machine oil needed for lubrication, cooling is provided to exhaust-gas turbocharger, make exhaust-gas turbocharger rotor at engine stoping operation, when making inertial rotation after oil pump fuel cut-off, still obtain the machine oil of sustainable supply, to guarantee the needs of lubrication and cooling, thus effectively extend the working life of exhaust-gas turbocharger.
Two. technical background:
Present exhaust gas turbocharge motor, due to oil pump and engine synchronization work.So before an engine is started, oil pump can not pump machine oil, now exhaust-gas turbocharger can not organic oil input.After the engine started, oil pump and exhaust-gas turbocharger operate simultaneously, and the machine oil pumped due to oil pump will by arriving the rotor bearing of exhaust-gas turbocharger after the oil transport pipeline of certain length, so the rotor bearing of exhaust-gas turbocharger had operated before machine oil arrives, start running to machine oil from exhaust-gas turbocharger and arrive bearing during this period of time, the rotor bearing of exhaust-gas turbocharger does not have machine oil to flow through, and the rotor bearing of exhaust-gas turbocharger now experienced by the coasting process under one section of inorganic oil supply status when engine stop last time, rotor bearing has been the state of place's insufficient lubrication, that is machine oil arrive before during this period of time, the rotor bearing of exhaust-gas turbocharger is entry into service under the condition state being in insufficient lubrication.
Due to when motor runs, the rotary speed of rotator of exhaust-gas turbocharger is very high, when engine stop works, oil pump also synchronously quits work, and now, the rotor of exhaust-gas turbocharger still under the effect of inertia from running up until continuous decrescence speed stops, that is after stopping pump oil from oil pump, rotor to exhaust-gas turbocharger shuts down during this period of time, the rotor of exhaust-gas turbocharger be in unlubricated and cooling needed for engine oil supplying condition state under carry out coasting, now, the wear extent of rotor bearing is maximum, this is also that most exhaust-gas turbocharger damages the main cause 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 in the state that runs up at once, the rotor of its exhaust-gas turbocharger has higher inertia rotating speed, thus the time that palpus High Rotation Speed is longer 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.Therefore the operating instruction of exhaust gas turbocharge motor are all advised, motor can be shut down after needing idle several minutes before shutting down; Its object mainly, make the rotor of exhaust-gas turbocharger can under the state having lasting machine oil to supply, after rotating speed is down to the rotating speed corresponding to during engine idle, row closes down motor again, under the state making the inorganic oil supply of the rotor of exhaust-gas turbocharger after engine stop, rotate to stopping with minimum inertia rotating speed, make the wear extent of rotor bearing be down to minimum, the working life of exhaust-gas turbocharger can be extended to the greatest extent; Even if operate like this, the rotor of exhaust-gas turbocharger still under the state of inorganic oil supply, need rotate to stopping from minimum inertia rotating speed.
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 need after engine stop inorganic oil supply state under from minimum inertia rotating speed rotate to stopping, during this period of time, the wear extent of rotor bearing is still far above the wear extent that rotor high-speed during organic oil supply status rotates; But also being directed at the initial stage of exhaust-gas turbocharger at lower task, rotor bearing operates under the state being in extremely insufficient lubrication.
Therefore supply seasonable wear extent to extend the working life of exhaust-gas turbocharger in order to reduce rotor at inorganic oil, just motor is closed down after all needing idle several minutes when closing down motor at every turn, this makes motor close at every turn all needs many wastes idling oil consumption of several minutes, and many number of discharges minute waste gas, this had both been unfavorable for environmental protection and energy-conservation social demand; Also hinder to use has the employing of the automobile of the motor of exhaust-gas turbocharger to carry out fuel-economizing operation without idling fuel-saving control pattern simultaneously.
For solving the problem of supplying without lasting machine oil when exhaust-gas turbocharger rotor is in inertial rotation after engine stop, need meaningless oil consumption and the toxic emission of idle several minutes before eliminating motor shutdown, the technical solution used in the present invention is:
Automatically supply the system of machine oil to exhaust-gas turbocharger, that is: oil supply system of exhaust gas turbocharger at the machine oil of former exhaust-gas turbocharger for increase by oil duct, its working principle is:
After engine oil pressure switch closes each time, automatically quit work again after oil supply system of exhaust gas turbocharger i.e. in good time one period artificially set that automatically works, oil supply system of exhaust gas turbocharger operationally, uses electric oil pump to supply machine oil to exhaust-gas turbocharger.
When engine oil pressure switch is in off state, namely oil supply system of exhaust gas turbocharger quits work automatically.
Advantage of the present invention is:
1. engine start is front when key switch is on position, engine oil pressure switch is in the bonding state of closed conducting under the effect of inorganic oil pressure, now, 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 exhaust-gas turbocharger before rotation, obtain machine oil supply.When after engine start, under the effect of engine oil pressure, when the Oil pressure switch of motor is in the non-bonding state of disconnection, namely oil supply system of exhaust gas turbocharger quits work automatically.
2. when after the engine stoping operation in running, namely oil pump synchronously quits work, the Oil pressure switch of motor is in closed conducting bonding state under the effect of inorganic oil pressure, now, oil supply system of exhaust gas turbocharger uses electric oil pump to supply machine oil to exhaust-gas turbocharger, to guarantee before rotor stops operating, the machine oil supply that the rotor bearing of exhaust-gas turbocharger obtains continuing for lubrication and cooling, and automatically stops the work of electric oil pump after set time.
