Description
Technical field
The present invention relates to a kind of turbocharger of motor and its system with Intelligent lubricating device, belongs to engine skill
Art field.
Background technique
The performances such as turbocharged engine dynamic property, economy and discharge are superior to traditional flat-absorpting type engine；How
With small discharge capacity, biggish power and less discharge are obtained, technology emphasis will be gathered in small displacement turbocharged engine
On machine, therefore turbocharging technology is also the trend of current fuel-engined vehicle development.But turbocharger is deposited during application
Greatest problem be lack of lubrication the phenomenon that, when including starting lubrication lag and it is flame-out after lubrication stop so that bearing exists
It cannot adequately be lubricated in a period of time after starting is first and flame-out, and lead to bearing wear, oil sealing damage, lubricating oil is inhaled
The phenomenon that entering engine, causing burn oil, while also reducing the service life of turbo-charger bearing.
As shown in Figure 1, former car engine turbocharger lubrication principle: driving mechanical lubricating oil pump by crankshaft timing gear
Work, machine oil is from engine sump tank --- ----lubricating oil pump (being pressurized to 0.2Mpa to 0.4 Mpa) --- --- main oil gallery --- ---
Turbocharger --- --- oil return pipe --- --- oil sump.Oil lubricating pressure is generated by engine driving lubricating oil pump, engine
Flame-out, lubricating oil pump stops working.
At this stage, the research both at home and abroad in relation to improvement turbocharger lubrication function, is concentrated mainly on rubbing for bearing material
Performance, lubrication oil supply method, lubrication oil supply pressure and fuel delivery etc. are wiped, and the research of additional lubrication device is also compared
It is few.
The bavin Wenhua of studio, locomotive depot, Inner Mongol Chifeng has carried out fuel feeding compensation dress with regard to diesel engine of locomotive turbocharger
The installation set, to improve the lubrication circumstances of TC bearings.The device main component is an oil storage tank, can be used as machine oil energy
Deposit, to solve the problems, such as booster moment oil starvation.Method is one check valve of installation, check valve on booster oil feed line
An oil storage tank in parallel afterwards, machine oil by check valve to booster and oil storage tank fuel feeding, into oil storage tank machine oil by gas in tank
Body compression, when gas pressure is consistent with booster fuel feeding working connection pressure in tank, machine oil stops (saying at this time to oil storage tank fuel feeding
Bright energy reserve has been expired).When booster fuel feeding working connection pressure is reduced, since oil storage pressure tank is high, at this moment oil storage tank will
Fuel feeding is supplemented to booster working connection, compensating action is played to booster fuel feeding.This current applicable cases of fuel feeding compensation device
Well, it is protected suitable for the bearing of locomotive turbo-charger, but the oil storage capacity of oil storage tank is limited, to reach more abundant profit
It is sliding, oil storage tank size need to be increased, become larger so as to cause the volume of engine, weight increases, and is unfavorable for integrally-built compact set
The optimization of meter and power.
The Zhang Huaiyong of Shandong region Shengli Oil Field General Transport Company has made a kind of turbocharger auxiliary lubricating device, should
Device is made of electrodynamic pump, storage oil tank, oil pipe and threeway, circuit control device.When ignition switch is threaded to 3 grades, prolong to energization
When relay power, control conduction time be 5s, operate oil pump.Machine oil reaches auxiliary by being sucked out in storage oil tank to booster
The effect of lubrication.After engine misses, the power-off of key switch route controls conduction time by cut-off relay as 3s, makes
Oil pump operating.Machine oil achievees the effect that lubrication assistant and cooling by being sucked out in oil storage tank to booster.Lubricating oil is low in oil storage tank
When normal line, main oil gallery hand-operated valve is opened, at this moment in the case where engine operates, lubricating oil is injected into oil storage tank.
When 3min reaches the oil level upper limit, cutting hand-operated valve disconnects oil circuit.The device can effectively play the effect of lubrication assistant booster, but
The starting of auxiliary lubricating device is controlled by the time entirely, and accuracy is not high；Oil storage tank need in addition be increased and add oil pipe and hand-operated valve,
Mechanism is excessively lengthy and tedious；Oil storage tank needs manual oil storage, easily causes oil storage not in time.
The Zhang Weibo etc. of University of Fuzhou has invented a kind of turbocharger lubrication device, contains instantaneous repairing in the device
Mechanism.The components of instantaneous repairing mechanism are more, including oil storage room, repairing pipe, oil inlet pipe, switch valve, electromagnet, piston and multiple
Position spring.Oil storage room accesses oil inlet pipe through repairing pipe, and repairing pipe is equipped with switch valve, and oil storage room is externally provided with electromagnet, oil storage room
It is interior to be equipped with piston and reset spring.Piston carries out forward motion by solenoid actuated, compresses the shoe cream room of oil storage room, realizes and mends
Oil；It is driven by reset spring and carries out counter motion, increase the shoe cream room of oil storage room, realize oil storage.The invention can be effectively improved profit
Sliding condition, but mechanism components are more, and structure is complex；Due to the resistance of lubricating oil, cause the movement of piston not sensitive enough.
It is above-mentioned the several of turbocharger lubrication function are improved with attachment device for China scientific research personnel to represent method, and state
Outer correlative study method is also rarely reported.
Configuration specific gravity with turbocharger in listing new car increases, it is contemplated that turbocharger demand speedup will surmount
Vehicle complete vehicle yield speedup.China turbocharger market has biggish growth prospect, the cooling and lubrication of turbocharger
Link has attracted wide public concern.Turbocharger currently on the market is all made of the machine oil profit of engine lubrication system main oil gallery
Sliding turbine wheel shaft and bearing inevitably influence its lubrication since turbocharger is in the working environment of high temperature hostile
Effect.
