Abstract
The utility model discloses a kind of turbocharger with machine oil leakage-resistant device, in oil return pipe under pressurizer shell, install the vavuum pump for making that vacuum is formed in housing additional, in the oil return pipe after vavuum pump, installing additional makes the gs-oil separator of the Oil-gas Separation by vavuum pump, the machine oil of the oil separation outlet of gs-oil separator flows back to engine sump, and the qi leel of gs-oil separator connects admission line from the air of outlet.Installed additional on original housing and mend the air of supercharging to turbine wheel behind, with the tonifying Qi pipeline of balance vacuum.The utility model can solve the technical problem of burn oil existing for traditional turbocharger.
Description
Technical field
It the utility model is related to a kind of improved technology of vehicle turbine increase device lubricating system.
Background technology
With the fast development of this Domestic Automotive Industry, all size engine with supercharger vehicle is more and more, although supercharging hair
Motivation is greatly improved in liter power, but also drastically increases exhaust emission.The wherein engine oil leakage of turbocharger
Oneself turns into a big factor of environmental pollution, and because it is a high temperature and high speed rotating device, it will not only have reliable cooling system,
Also there are enough lubricating systems just to can guarantee that its continuous and effective operates.But the use passed through for many years is found, lubricating system itself
Engine oil leakage phenomenon be present, some new cars are just than more serious, caused by this is mainly fault of construction itself.The oil of turbocharger
Envelope is ring type metal movable fit structure, along with partial pressure differential environmental factor in booster, some machine oil is oozed by booster
Leak gasification, and combustion.Thus very big environmental pollution, especially Beijing-Tianjin Ji area size vehicle ratio are caused to many areas in China
Compared with concentration, annual winter haze is increasingly severe.
Original turbocharger lubrication system is shown in Figure 1, the lubricating oil after lubrication, by being set below housing
Some pipeline selfs are returned in engine sump, although flowing back no resistance from top to bottom, when turbine rotates at a high speed, and whirlpool
Wheel and turbine produce vortex behind, make to be partially formed certain negative pressure, the ring type oil that the machine oil in booster shell is passed through both sides
Envelope is sucked out.The machine oil gasification of sucking-off is entered cylinder burning by air inlet turbine when high speed rotates with this air, while also makes air inlet pipe
Road air throttle and inlet valve periphery form substantial amounts of carbon deposit, if on schedule cleaning can cause not smooth engine charge, bad Acceleration,
Influence dynamic property.Exhaust driven gas turbine is similarly the machine oil direct gasification burning sucking-off, causes certain machine oil that should not be consumed
Consumption directly increases exhaust emission.
The content of the invention
The purpose of this utility model is to provide a kind of turbocharger with machine oil leakage-resistant device, traditional to solve
The technical problem of burn oil existing for turbocharger.
In order to realize foregoing invention purpose, this is as follows with new used technical scheme：
A kind of turbocharger with machine oil leakage-resistant device, in oil return pipe under pressurizer shell, installation makes housing
The interior vavuum pump for forming vacuum, in the oil return pipe after vavuum pump, install the oil gas point made by the Oil-gas Separation of vavuum pump additional
From device, the machine oil of the oil separation outlet of gs-oil separator flows back to engine sump, and the qi leel of gs-oil separator is from outlet
Air connect admission line.
Installed additional on original housing and mend the air of supercharging to turbine wheel behind, with the blowdown pipe of balance vacuum
Road.
The utility model has the advantage that and good effect：
By balancing the vacuum in booster pump, it can avoid air inlet turbine that the machine oil of sucking-off is gasified when high speed rotates
As air enters cylinder burning, admission line air throttle and inlet valve periphery is formed substantial amounts of carbon deposit, cause engine charge not
Freely, bad Acceleration, influence dynamic property；Equally avoid the machine oil directly discharge of burning and increase exhaust emission.

Embodiment
A kind of turbocharger with machine oil leakage-resistant device described in the utility model, the oil return pipe under pressurizer shell
In, install the vavuum pump 24 for making that vacuum is formed in housing additional, in the machine oil oil return pipe 23 after vavuum pump 24, installation makes by true
The gs-oil separator 25 of the Oil-gas Separation of empty pump, the machine oil of the oil separation outlet 27 of gs-oil separator 25 flow back to crankcase oils bottom
Shell, the qi leel of gs-oil separator connect admission line from the air of outlet 26.
Installed additional on original housing and mend the air of supercharging to turbine wheel behind, with the blowdown pipe of balance vacuum
Road.Air duct after the supercharging for the compressor impeller side that the tonifying Qi road one end is located at booster, the other end are located at booster
Turbine wheel side.Embodiment is at the cavity being added into air between turbine wheel and oil sealing, can be passed through
Housing upper shed and the mode of tonifying Qi pipeline is installed realized in this place.
Shown in Figure 3, installation vavuum pump makes to form vacuum in housing among oil return pipe under pressurizer shell, balance shell
Inside and outside pressure difference prevents machine oil from being sucked out, and installing gs-oil separator additional makes to flow back to song by separation, machine oil by the oil gas of vavuum pump
Axle box oil sump, air connect admission line.Turbocharger in Fig. 3 is existing structure.
It is shown in Figure 2, then install tonifying Qi pipeline additional on original housing, the air by supercharging is mended to impeller behind
Balance vacuum.Especially turbine wheel (exhaust driven gas turbine) fills certain air behind, can not only balance vacuum, moreover it is possible to rises
Promoting combustion waste gas to catalysis makes more to tie only by the waste gas of three-element catalytic.Progressively solve the problems, such as that booster automobile discharge is big.
