Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile engineering, in particular to a respirator pipeline, an engine system and an automobile. Background Art
[0002] The crankcase ventilation system is a system used to treat the oil vapor in the engine crankcase. The system has two structures, one is an open structure and the other is a closed structure. The open structure directly discharges the treated gas into the atmosphere, while the closed structure transmits the treated gas back to the engine's intake pipe through the breather pipe for reburning. The system includes components such as a crankcase breather and a breather pipe. Among them, the crankcase breather is the core component of the ventilation system. It is responsible for filtering and / or treating oil vapor, and effectively discharging or circulating combustion through the breather pipe to maintain the pressure balance in the crankcase and reduce pollution to the environment.
[0003] However, in low-temperature environments, the breather pipes of the above two structures are prone to ice blockage, which causes the crankcase pressure to increase, and then causes serious problems such as oil seal leakage and oil pan rupture.
[0004] In order to solve this problem, existing technical solutions usually include optimizing the direction of the respirator pipeline to avoid windward cooling, adding insulation materials to the respirator pipeline, and adding local electric heating to the outside of the respirator pipeline. However, these solutions have limited effects and still fail to effectively solve the problem of respirator pipeline icing. Utility Model Content

[0023] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.
[0024] There are currently several solutions to solve the problem of ice blockage in the breather pipe of the crankcase ventilation system, but all of them have limitations and cannot solve the above problems well. For example, if the direction of the breather pipe is optimized to avoid windward cooling, multiple factors such as pipe length and bending angle need to be considered; if insulation materials are added to the outside of the breather pipe, additional material and energy costs will be consumed; if local electric heating is added to the outside of the breather pipe, issues such as heating uniformity and safety need to be considered.
[0025] Based on this, an embodiment of the present disclosure provides a respirator pipeline that can effectively solve the problem of icing in different parts of the respirator pipeline.
[0026] Figure 1 FIG. 1 is a schematic diagram of a respirator circuit according to an exemplary embodiment. Figure 1 As shown, the breather pipeline includes a pipeline body 1 and a heating element 2 . The pipeline body 1 is connected to the crankcase breather; the heating element 2 is arranged inside the pipeline body 1 and penetrates the inside of the pipeline body 1 .
[0027] In some embodiments, the arrangement direction of the heating element 2 is consistent with the direction of the pipe body 1 so as to heat various parts inside the pipe body 1.
[0028] In some embodiments, the heating element 2 may be one or more heating wires. Since the pipe body 1 is a hollow structure, one or more heating wires may be introduced from one end of the pipe body 1 and passed through the hollow structure and led out from the other end.
[0029] In a specific embodiment, the heating element 2 can be a heating wire. For example, a heating wire with a length of 2 m can be selected to pass through the interior of the pipe body 1, so as to achieve heating of various parts inside the pipe body 1. It should be noted that since the heating wire runs through the interior of the pipe body 1, the gas inside the pipe body 1 can directly contact the heating wire, and the heat on the heating wire can be evenly transferred to the gas inside the pipe body 1, so as to achieve heating of the gas inside the pipe body 1 and prevent it from condensing into ice at low temperatures.
[0030] In another specific embodiment, the heating element 2 may be a plurality of heating wires. For example, three heating wires of the same length may be selected and evenly spaced inside the pipe body 1. For example, the three heating wires may be arranged inside the pipe body 1 by fixing them with slots at both ends of the lead-in and lead-out to ensure that they are evenly arranged in the hollow structure of the pipe body 1. That is, the three heating wires are evenly arranged in the hollow structure of the pipe body 1.
[0031] It is understandable that providing multiple heating wires can increase the contact area between the gas inside the pipe body 1 and the heating wires, thereby increasing the heating power and improving the heating efficiency of the inside of the pipe body 1. However, it should be noted that although multiple heating wires can increase the heating power, the more the better. Excessive heating power will burden the engine and may cause the internal pressure of the pipe body 1 to be too high. Therefore, it is necessary to reasonably control the heating power to ensure that the gas inside the pipe body 1 can be heated smoothly while avoiding unnecessary damage to the engine.
[0032] In the above embodiments, one or more heating wires are arranged inside the pipeline body 1 by threading. This threading method has the following advantages: 1. It can ensure that the heating wires are evenly distributed inside the pipeline, so as to achieve average heating of the entire pipeline. 2. It can avoid problems such as excessively high or low local temperatures in the pipeline, thermal stress, deformation, etc. 3. The heating wire can be relatively easy to install and disassemble, which is convenient for maintenance and replacement. 4. Compared with other heating methods, such as outer layer heating, patch heating, etc., the threading method can achieve pipeline heating without taking up too much space, saving space resources and costs.
[0033] It should be noted that the arrangement of the above-mentioned multiple heating wires can be at least one of spiral winding, parallel arrangement, cross arrangement, and mesh arrangement. In the embodiment of the present disclosure, the heating wires can be arranged in a suitable arrangement based on the specific conditions of different parts of the respirator pipeline, and this is not specifically limited in the embodiment of the present disclosure.
[0034] See also Figure 1 In some embodiments, the respirator circuit further includes a heater connector 3 , which is respectively connected to the heater 2 and an engine wiring harness (not shown in the figure) for providing current to the heater 2 .
[0035] Furthermore, the respirator pipeline also includes a heating control switch 4, and the heating element connector 3 is connected to the engine wiring harness through the heating control switch 4 to control the connection or disconnection of the current of the heating element 2 when the heating control switch 4 is turned on or off. Among them, adding the heating control switch 4 can flexibly control the heating time of the heating element 2 as needed.
[0036] The above technical solution of the embodiment of the present disclosure realizes uniform heating of the inside of the respirator pipeline by building a heating element 2 into the structure of the original pipeline body 1, which can effectively solve the problem of ice formation in different parts of the respirator pipeline in a low temperature environment.
[0037] Figure 2 is a schematic block diagram of an engine system according to an exemplary embodiment. Figure 2 As shown, the engine system 100 includes: a crankcase 110 and a crankcase ventilation system 120. The crankcase ventilation system 120 includes a crankcase breather 121 and the above-mentioned breather pipeline 122. The crankcase 110 is connected to the crankcase breather 121, and the crankcase breather 121 is connected to the breather pipeline 122.
[0038] In some embodiments, the structure of the crankcase ventilation system 120 can be an open structure or a closed structure. In the open structure, the end of the breather pipe 122 is directly connected to the atmosphere, and the crankcase breather discharges the filtered gas into the atmosphere through the breather pipe 122; in the closed structure, the end of the breather pipe 122 is connected to the intake pipe of the engine, and the crankcase breather transmits the filtered gas back to the intake pipe of the engine through the breather pipe 122. The breather pipe 122 provided in the embodiment of the present disclosure can be applicable to but not limited to the crankcase ventilation systems of the above two structures.
[0039] Specifically, when the engine is started, oil vapor is generated in the crankcase 110, and the crankcase breather 121 can filter the oil vapor generated in the crankcase, and transmit the filtered air to the engine or the atmosphere through the breather pipe 122 to maintain the pressure balance in the crankcase 110. These three work together to ensure the normal operation and high efficiency of the engine system.
[0040] The disclosed embodiment improves the respirator pipe 122 (i.e., adds a heating element inside it), which can effectively prevent the problem of ice forming in different parts of the respirator pipe, avoid engine damage, vehicle breakdown and other problems caused by blockage of the respirator pipe, and improve transportation efficiency.
