Problems solved by technology
[0002] When the engine is working, the high-pressure gas formed by fuel combustion pushes the piston to move in the cylinder, thereby driving the crankshaft to rotate. The gap between the moving pairs in the cylinder causes the high-pressure gas to leak into the crankcase, gear chamber, oil pan, etc. into the connected cavity. As a result, the air pressure in the cavity rises, causing damage to the seal and other failures, and the air pressure in the cavity must be released
At the same time, if the oil and gas in the crankcase are directly discharged into the atmosphere, it will not only increase the fuel consumption of the engine, but also pollute the environment, so it is necessary to separate the oil and gas

The invention discloses an engine respirator air pipe. The respirator connecting pipe is a straight-through pipe structure arranged vertically, and the upper end communicates with the air outlet of the respirator; the main air outlet pipe is a straight-through pipe structure arranged vertically; the auxiliary air outlet tee joint includes: a respirator connecting pipe And the main outlet pipe joint, as well as the auxiliary outlet pipe of the vertical respirator joint and the main outlet pipe joint; the respirator connection is connected with the lower end of the respirator connection, and the upper end of the main outlet pipe is connected with the lower end of the main outlet pipe joint, making the auxiliary outlet tee The connector is located near the intake end of the engine breather snorkel; the auxiliary outlet is set laterally. The air pipe of the engine respirator adopts an auxiliary air outlet tee joint at the upper part. When the end of the main air outlet pipe is frozen and blocked, the exhaust gas is discharged from the auxiliary air outlet pipe of the auxiliary air outlet tee joint, which can prevent blockage under low temperature conditions and cause exhaust gas of the respirator. It cannot be ruled out to cause oil leakage.
Description
technical field [0001] The invention relates to the field of engines, in particular to an engine respirator vent pipe. Background technique [0002] When the engine is working, the high-pressure gas formed by fuel combustion pushes the piston to move in the cylinder, thereby driving the crankshaft to rotate. The gap between the moving pairs in the cylinder causes the high-pressure gas to leak into the crankcase, gear chamber, oil pan, etc. into the connected cavity. As a result, the air pressure in the cavity rises, causing failures such as damage to the seal, and the air pressure in the cavity must be released. At the same time, if the oil and gas in the crankcase are directly discharged into the atmosphere, it will not only increase the fuel consumption of the engine, but also pollute the environment, so it is necessary to separate the oil and gas. These problems all need to be solved by the engine breather device. [0003] For the natural ventilation crankcase ventilati...
