The automatic outage delay device can automatically control a motor-driven oil pump to supply engine oil to the exhaust turbocharged engine before and after the engine is started, so that the condition that a rotor of the exhaust turbocharged engine runs without engine oil supply before and after the engine is started is eliminated, and the abrasion of a rotor bearing of the exhaust turbocharged engine is efficiently reduced, the operation of idling for minutes when the exhaust turbocharged engine is closed is no longer needed, the operation burden for operating the exhaust turbocharged engine is efficiently relieved, the fuel consumption is decreased and the exhaust emission is reduced.
Description
One. technical field:
The present invention relates to one can be after tail-off ignition switch, can be in good time to the automatic outage delay device of auto-breaking again after electric oil pump energising a period of time, this device also can be controlled at the energising of engine start forward direction electric oil pump automatically, and does not switch on to electric oil pump in the time of engine running.
Two. technical background:
Present exhaust gas turbocharge motor, delivers to this process need experience a period of time of exhaust-gas turbocharger from starting to oil pump by oil pump, and within this period of time, the rotor bearing of exhaust-gas turbocharger turns round under inorganic oil supply status.
In the time of exhaust gas turbocharge engine stoping operation, the rotor in its exhaust-gas turbocharger does not stop the rotation with engine synchronization, and its rotor, under the effect of inertia, needs experience to slow down until stop this process through nature from High Rotation Speed state; In this course, because motor shuts down, its oil pump fuel cut-off, now the rotor bearing of exhaust-gas turbocharger turns round under inorganic oil supply status; If motor is to transfer to and shutting down from the moment that runs up, the rotor bearing of exhaust-gas turbocharger will be under inorganic oil supply status the longer time of coasting.Because the rotor bearing of present exhaust-gas turbocharger can not be exempted to move the in the situation that of will experiencing above-mentioned inorganic oil supply status in engine working process, to the rotor that makes exhaust-gas turbocharger when the coasting, the wear extent of its bearing increases, and much larger than the wear extent in effective when running.
Three. summary of the invention
Present exhaust gas turbocharge motor, the lubricated required machine oil of rotor bearing when its exhaust-gas turbocharger work is to be supplied by the oil pump of motor.Therefore deposit in the time that exhaust gas turbocharge motor normally uses
There is following problem:
(1) from engine start, to oil pump, machine oil is delivered to this process need experience a period of time of exhaust-gas turbocharger, within this period of time, the rotor bearing of exhaust-gas turbocharger turns round under inorganic oil supply status.
(2) at engine stoping operation, its oil pump is synchronously after fuel cut-off, and the rotor in exhaust-gas turbocharger also needs experience to slow down until stop this process through nature from High Rotation Speed state under the effect of inertia; In this course, the rotor bearing of exhaust-gas turbocharger is done coasting under inorganic oil supply status.
Two above-mentioned problems are the main causes that cause now the wearing and tearing of exhaust-gas turbocharger rotor bearing, especially transferring to from the moment that runs up at motor and shutting down, because the rotor speed of exhaust-gas turbocharger is now higher, inertia is larger, and the time that rotor bearing must turn round under the state of inorganic oil supply is longer.For extend the working life of exhaust-gas turbocharger as far as possible, the current conventional method of remedying is that driver advises in operating instruction in the manufacturer of exhaust gas turbocharge motor, in the time that needs are closed down motor, should first allow engine idling operation number minute, and then close down motor.Its objective is and having under the state of lasting machine oil supply, the rotor speed of exhaust-gas turbocharger is down to minimum, make the inertial rotation time of rotor under the state of inorganic oil supply reduce to the shortest.But this rotor bearing of still failing to eliminate exhaust-gas turbocharger, in the normal using process of exhaust gas turbocharge motor, still must experience the situation of doing coasting under inorganic oil supply status; But also increased the reactive power consumption of fuel oil, also increase toxic emission, and wasted driver's operating time and increased the psychological burden of operation.
For eliminating the rotor shaft of exhaust-gas turbocharger in the normal using process of turbosupercharged engine, must experience the situation of doing coasting under inorganic oil supply status.The technological scheme that the present invention takes is:
Use automatic outage delay device control electric oil pump before engine start, and continue supply machine oil from trend turbosupercharger in motor a period of time after closing down.Thereby the rotor bearing of eliminating exhaust-gas turbocharger must experience the situation of doing coasting under inorganic oil supply status in the normal using process of exhaust gas turbocharge motor.
The working effect of automatic outage delay device is as follows:
(1) work of automatic outage delay device control electric oil pump just extends the working life of exhaust-gas turbocharger rotor bearing; before omitting exhaust gas turbocharge engine shutdown, must operate by idling number minute, do not change the original performance of exhaust gas turbocharge motor and vehicle thereof.
(2) driver is in the process of ato unit, and when key switch forwards on position to from off position, automatic outage delay device can move operation of oil pump by automatic control electric, continues supply machine oil to exhaust-gas turbocharger.
(3), after motor is activated, the moving oil pump of automatic outage delay device automatic control electric quits work.
(4) when motor is closed after stall, automatic outage delay device can continue supply machine oil to exhaust-gas turbocharger by the moving operation of oil pump of automatic control electric, and order is to one section of set time of electric oil pump continuous firing, until the rotor in exhaust-gas turbocharger under the effect of inertia from High Rotation Speed state through naturally slowing down until after stopping, the moving oil pump of automatic control electric quits work again.
Adopt after the present invention, exhaust gas turbocharge motor is in normal using process, the moving oil pump of automatic outage delay device automatic control electric can be in the time that the oil pump of motor be not yet worked, i.e. moment before exhaust-gas turbocharger rotor is about to rotation, and exhaust-gas turbocharger rotor continues supply machine oil to exhaust-gas turbocharger during making inertial rotation.
Advantage of the present invention has:
(1) can move oil pump in the time that engine oil pump is not worked by automatic control electric, be that rotor in exhaust-gas turbocharger is about to the moment before rotation, and rotor is during making inertial rotation, to exhaust-gas turbocharger supply machine oil, after again can set time, the moving oil pump of automatic control electric quits work, thereby greatly reduce the wear extent of exhaust-gas turbocharger rotor bearing, extend the working life of exhaust-gas turbocharger, then reduced the user cost of turbosupercharged engine.
(2) energy-saving and environmental protection, it can make driver indiscriminately ad. as one wishes close waste gas and close turbosupercharged engine, and without scrupling exhaust-gas turbocharger in which kind of state, thereby reduce the idle required fuel consume that must carry out several minutes before at every turn killing engine, eliminate the waste gas discharging must carry out several minutes idle before killing engine time, and can extend again the life-span of exhaust-gas turbocharger.
(3) because driver can indiscriminately ad. as one wishes close exhaust gas turbocharge motor and don't can shorten life-span of waste gas exhaust-gas turbocharger.Psychological burden when this can reduce driver operation.
