The embodiment also relates to a crankcase breather pipe which can prevent the pressure of a crankcase from being too high, prolong the service life of engine oil, reduce the abrasion and corrosion of parts and prevent the oil leakage of an engine. The intake pipe body and the crankcase breather pipe are connected by a crankcase breather pipe joint 1.

In fig. 4, the direction of the gas flow in the crankcase breather pipe is indicated by a solid line, and the direction of the gas flow in the intake pipe body is indicated by a broken line. Fig. 1 is an exploded view of an engine intake pipe structure according to an embodiment of the present invention. According to an embodiment of the present invention, with the opposite direction of the air flow direction in the intake pipe main body as a reference direction, the intake pipe main body can be divided into a front-stage outer shell 4 and a rear-stage pipeline 2, the inner core 3 is disposed in the intake pipe main body and located between the front-stage outer shell 4 and the rear-stage pipeline 2, and the front-stage outer shell 4 is connected to the crankcase breather pipe through the crankcase breather pipe joint 1, so that in the intake pipe main body, the gas from the crankcase breather pipe must pass through the inner core 3 after being merged with the gas in the intake pipe main body.
According to one embodiment of the invention, the inner core 3 is generally tubular so as to be arranged inside the intake pipe body, and the wall of the inner core 3 is provided with small holes 313, so that a cavity for collecting cold and hot gases of the engine is formed between the wall of the inner core 3 and the intake pipe. It will be appreciated that the cavity is defined by the air inlet tube body and the walls of the inner core 3 and that the walls of the inner core 3 block the cavity from the interior of the inner core 3 so that the temperature within the cavity is different from that of the inner core 3.
Fig. 1 is an exploded view of an engine intake pipe structure according to an embodiment of the present invention. Fig. 2 is a schematic view of a first core construction according to an embodiment of the present invention. Fig. 3 is a schematic view of a second core structure according to an embodiment of the present invention. According to one embodiment of the present invention, the inner core 3 comprises a first inner core 31 and a second inner core 32 coaxially arranged, the first inner core 31 comprises a first core tube 311 and a first baffle 312 arranged at the periphery of the first core tube 311, the second inner core 32 comprises a second core tube 321 and a second baffle 322 arranged at the periphery of the second core tube 321, and the section of the first inner core 31 between the first baffle 312 and the second baffle 322 is provided with small holes 313. The first baffle 312 and the second baffle 322 are both annular, and the outer edges of the first baffle 312 and the second baffle 322 are connected with the inner edge of the air inlet pipe main body. Since the first inner core 31 and the second inner core 32 are coaxially disposed and both the first inner core 31 and the second inner core 32 are located in the intake pipe main body, the first barrier 312 and the second barrier 322 define the boundary of the cavity, so that the cavity communicates with the core pipe through the small hole 313.
According to an embodiment of the present invention, the first core 31 and the second core 32 are separately provided so as to be fittingly installed in the main air inlet pipe. When the connection is carried out, the first core tube 311 of the first inner core 31 is inserted into the front section outer shell 4, the second core tube 321 of the second inner core 32 is inserted into the rear section pipeline 2, and the front section outer shell 4 and the rear section pipeline 2 are connected through a common technical means, the connection has certain sealing performance, and the common technical means can be bolt connection or welding or riveting.

In yet another embodiment, the first core tube 311 has at least a gap 315 with the inlet pipe body, while the second core tube 321 has at least a gap 315 with the inlet pipe body. The air flow from the crankcase breather tube may have a longer stroke within the cavity.
According to one embodiment of the present invention, the small hole 313 in the first core tube 311 is provided around the first core tube 311. One circle here means that the small holes 313 on the first core tube 311 are surrounded by a circle at a set interval, so that the number of the small holes 313 is larger, and when one small hole 313 is blocked by frost, the other small holes 313 can be ventilated normally.
