Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to an air-driven respirator device with integrated oil heating. Background Art

[0002] The combustion products of natural gas engines contain a lot of water, so the crankcase exhaust gas has a higher water content than diesel engines. This poses a greater challenge to the icing problem of crankcase ventilation systems in cold regions. Among them, air-driven respirators have the advantages of low cost, simple structure and reliability, but the icing problem has always troubled customers.

[0003] The defects of the prior art are:

[0004] Since the combustion products of natural gas engines contain a large amount of water, there is a risk of freezing in the crankcase ventilation system in cold areas. Summary of the invention

[0005] In view of the above problems, the utility model provides an air-driven respirator device with integrated oil heating, which aims to quickly heat the respirator to prevent freezing, and does not require additional oil return pipes.

[0006] In order to solve the above problems, the technical solution provided by the utility model is:

[0007] An air-driven respirator device with integrated oil heating comprises a respirator body and a heating oil pipe, wherein: one end of the heating oil pipe is connected to the main oil channel of the engine cylinder block, and the other end is connected to the heating oil inlet on the respirator body; the respirator body is installed on the air intake side of the engine near the rear end; a heating oil outlet is provided at the connection between the respirator body and the inside of the engine; an oil channel is provided at the bottom of the respirator body; the oil channel connects the heating oil inlet with the heating oil outlet.

[0008] Preferably, a mounting flange is provided at the connection between the respirator body and the interior of the engine; after the mounting flange is fixedly connected to the corresponding position inside the engine, the internal cavity of the respirator body is connected to the crankcase and oil pan of the engine, and the oil channel is connected to the oil pan.

[0009] Preferably, the arrangement path of the oil channel passes through the oil return one-way valve at the bottom of the respirator body and the bottleneck position which is easily blocked by ice.

[0010] Preferably, the respirator body is made of cast aluminum.

[0011] Preferably, the heating oil pipe is made of metal at both ends, nylon inner layer in the middle section, and metal braided outer layer.

[0012] Preferably, the heating oil pipe has an inner diameter of 4 mm, a wall thickness of 1 mm, and a total length of 40 cm.

[0013] Preferably, the mounting flange is fixedly connected to the engine block by three M8 bolts.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. Since the utility model integrates a breather for heating the oil passage in the housing, the breather is quickly heated by the heat of the oil after the engine is started, thereby preventing freezing.

[0016] 2. Since the oil return channel is designed inside the breather of the utility model, the heated engine oil directly returns to the oil pan through the breather, so there is no need to arrange an additional oil return pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is further explained below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an air-driven respirator device with integrated oil heating comprises a respirator body 1 and a heating oil pipe 2, wherein: one end of the heating oil pipe 2 is connected to the main oil channel of the engine cylinder block, and the other end is connected to the heating oil inlet 1.1 on the respirator body 1; the respirator body 1 is installed on the air intake side of the engine near the rear end; a heating oil outlet 1.2 is provided at the connection between the respirator body 1 and the inside of the engine; an oil channel 1.3 is provided at the bottom of the respirator body 1; the oil channel 1.3 connects the heating oil inlet 1.1 with the heating oil outlet 1.2; a mounting flange 1.4 is provided at the connection between the respirator body 1 and the inside of the engine; after the mounting flange 1.4 is fixedly connected to the corresponding position inside the engine, the internal cavity of the respirator body 1 is connected to the crankcase and oil pan of the engine, and the oil channel 1.3 is connected to the oil pan at the same time.

[0025] It should be noted that the arrangement path of the oil channel 1.3 passes through the oil return one-way valve 1.5 at the bottom of the respirator body 1 and the bottleneck position which is easily blocked by ice.

[0026] It should be further explained that the heat from the oil after the engine is started can quickly heat the breather to prevent freezing, and the heated oil returns directly to the engine oil pan without the need for an additional oil return pipe.

[0027] It should be further explained that since the engine intake side is the cold side, the temperature rises slowly in a low temperature environment, so it is particularly important to use auxiliary oil heating.
