Abstract
The utility model relates to an internal combustion engine crankcase exhaust purification guide device assembly, comprising an oil gas mixture gas pipe, a positioning bolt, a pipeline positioning pipe, a diversion port, an oil gas separation material and an oil gas separation box, characterized in that: the oil gas mixture gas pipe is connected with the oil gas separation box and extends into the oil gas separation material in the oil gas separation box, one side of the oil gas separation box is connected with the diversion port, the diversion port is fixedly connected with a test-bed tail-gas pipe by the pipeline positioning pipe and the positioning bolt. After the oil and gas are shunted and the gas is guided by an open type diversion device, the influence on the pressure of an engine crankcase due to over large negative pressure of an engine exhaust pipe is avoided and the exhaust is purified when the normal work state of the engine self-crankcase is ensured.
Description
Technical field
The utility model relates to a kind of crank case of internal combustion engine waste gas purification gatherer assembly, belongs to engine rig test crankcase waste gas Treatment Technology field.
Background technology
At present; Because engine environment storehouse testing laboratory adopts the enclosed air exchange system, engine crankcase waste gas directly enters in the cabin, causes waste gas to remove; Testing crew and environment have been caused very big harm; The characteristics in combining environmental storehouse self have been studied a kind of crank case of internal combustion engine waste gas gatherer assembly, can reduce the harm of waste gas to environment storehouse testing laboratory like this.
Summary of the invention
The purpose of the utility model provides a kind of crank case of internal combustion engine waste gas purification guiding device assembly; It adopts the air guide of open type guiding device in oil gas shunting back; Avoided because of the excessive pressure to engine crankcase of engine exhaust pipeline negative pressure impacts, guaranteed to accomplish waste gas purification under engine self the crankcase normal operating conditions.
The technical scheme of the utility model is achieved in that a kind of crankcase waste gas purifies the guiding device assembly; By fuel-air mixture pipeline, bolt, pipeline positioning pipe, flow-guiding mouth, gas-oil separation material, gas-oil separation case, form; It is characterized in that: the fuel-air mixture pipeline is connected with the gas-oil separation case and stretches in the gas-oil separation material in the gas-oil separation case; Gas-oil separation case one side is connected with flow-guiding mouth, and flow-guiding mouth is fixedly connected with the test-bed offgas duct through pipeline positioning pipe, bolt.
The good effect of the utility model is to have avoided because of the excessive pressure to engine crankcase of engine exhaust pipeline negative pressure impacts, and is guaranteeing to accomplish waste gas purification under engine self the crankcase normal operating conditions.
Description of drawings
Fig. 1 is mechanism's diagrammatic cross-section of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further: as shown in Figure 1; A kind of crankcase waste gas purifies the guiding device assembly; By fuel-air mixture pipeline 1, bolt 2, pipeline positioning pipe 3, flow-guiding mouth 4, gas-oil separation material 5, gas-oil separation case 6, form; It is characterized in that: fuel-air mixture pipeline 1 is connected with gas-oil separation case 6 and stretches in the gas-oil separation material 5 in the gas-oil separation case 6; Gas-oil separation case 6 one sides are connected with flow-guiding mouth 4, and flow-guiding mouth 4 is fixedly connected with test-bed offgas duct 7 through pipeline positioning pipe 3, bolt 2.
Embodiment:
As shown in Figure 1, after crankcase waste gas enters into gas-oil separation case 6 from fuel-air mixture pipeline 1, separate through gas-oil separation material 5; Rely on gravity sensing simultaneously, machine oil will stay in the gas-oil separation case 6, and gas will flow into flow-guiding mouth 4 along pipeline; Under the effect of negative pressure, gas will enter into test-bed offgas duct 7, because flow-guiding mouth belongs to open type; Therefore both can be incorporated into exhaust pipe to waste gas, guarantee not destroy self pressure of engine crankcase again, realize successfully that crankcase waste gas handled; The environment in storehouse free from environmental pollution does not work the mischief to the people yet, and this installation cost is very low simultaneously.
