Description
Technical field
It the utility model is related to a kind of automotive engine component, and in particular to a kind of automobile engine cylinder-body.
Background technology
In engine operation process, piston ring position has a small amount of gas leakage to enter in engine body, and gas leakage is a kind of
Mixed gas, wherein containing a large amount of steam, the tail gas of burning generation, gasoline etc., mixed gas is isolated by gs-oil separator
Machine oil, and gasoline, combustion tail gas, steam etc. will enter engine aspirating system circulating combustion again, to reduce exhaust emission.
Existing gs-oil separator and engine cylinder body are fitted by what pipeline connection was realized, and such design exists
Following problem：（1）Connecting line is longer, of high cost, complex process；（2）Under extremely cold environment, connecting line is subject to cold air
Brush, gasoline and moisture condensation can be caused not to discharge, or even freeze.
The content of the invention
The purpose of this utility model is to provide a kind of automobile engine cylinder-body, to realize the assembling of gs-oil separator, at the same time
Connecting line is omitted, mitigates engine cylinder body weight, reduces cost.
The remote gearbox side integrally casting of automobile engine cylinder-body described in the utility model has gs-oil separator cloth
Chamber, inlet channel and exhaust passage are put, inlet channel is located at below gs-oil separator arrangement chamber and arranges chamber with gs-oil separator
Connection, exhaust passage are located above gs-oil separator arrangement chamber；Gs-oil separator stretches into gs-oil separator arrangement intracavitary and installs
When on the cylinder body, gs-oil separator arranges fuel-air mixture entrance, oil return opening and oil gas point of the chamber by gs-oil separator
Connected from device, exhaust passage is connected by the gas vent of its exhaust entrance, gs-oil separator with gs-oil separator.
The gs-oil separator arrangement chamber is cast in the top of the remote gearbox side of the cylinder body.
The inlet channel has two.
The fuel-air mixture of engine piston leakage enters by inlet channel, gs-oil separator arrangement chamber, fuel-air mixture
Mouth, which enters, carries out Oil-gas Separation in gs-oil separator, the gas after separation enters exhaust passage by gas vent, exhaust entrance,
Engine cylinder body is then discharged out, is burnt again into gas handling system, and the machine oil after separating passes through oil return opening, gs-oil separator cloth
Put chamber, inlet channel flows back to oil sump.
The utility model has the effect that：
（1）Gs-oil separator arrangement chamber, inlet channel and exhaust passage are cast in engine cylinder body, and technique is simple, empty
The structure design of chamber and passage not only saves material, but also alleviates engine cylinder body weight.
（2）When gs-oil separator stretches into gs-oil separator arrangement intracavitary and is installed on engine cylinder body, gs-oil separator
Arrangement chamber is connected by fuel-air mixture entrance, the oil return opening of gs-oil separator with gs-oil separator, and exhaust passage is arranged by it
Gas entrance, the gas vent of gs-oil separator are connected with gs-oil separator, pass through engine cylinder body inner passage（That is Oil-gas Separation
Device arrangement chamber, inlet channel and exhaust passage）The gas flowing before and after Oil-gas Separation is completed, without in addition installing connecting line additional,
Space and pipeline have been saved, has reduced cost, while also save assembly space.
（3）Gs-oil separator stretches into gs-oil separator arrangement intracavitary, and engine cylinder body heat content can improve gs-oil separator
Interior temperature, avoids gas mixture and condenses or freeze to the cold.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the schematic cross-section of the utility model.
Fig. 3 is the assembling schematic diagram of the utility model and gs-oil separator.
Fig. 4 is the structure diagram of gs-oil separator.

Gas vent 42 is offered on the right shell body of separator 4.
As shown in figure 3, the left shell of gs-oil separator 4 is stretched into gs-oil separator arrangement chamber 1, the right side of gs-oil separator 4
Housing is bolted on engine cylinder body, and gs-oil separator arrangement chamber 1 passes through 41, two oil returns of fuel-air mixture entrance
Mouth 43 is connected with gs-oil separator 4, and exhaust passage 3 is connected by its exhaust entrance 31, gas vent 42 with gs-oil separator 4.
The fuel-air mixture of engine piston leakage is mixed by two inlet channels 2, gs-oil separator arrangement chamber 1, oil gas
Close gas entrance 41 and enter the interior progress Oil-gas Separation of gs-oil separator 4, the gas after separation passes through gas vent 42, exhaust entrance 31
Into exhaust passage 3, engine cylinder body is then discharged out, is burnt again into gas handling system, and the machine oil after separating passes through two
