Embodiment Construction

[0019] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0020] Such as figure 1 As shown, the vehicle pipeline connection joint of this embodiment includes a joint body 1 and a central hole 2, and the central hole 2 runs through the joint body 1. The vehicle pipeline connection joint also includes a bracket 3, which is located in the middle section of the joint body 1, and the bracket It includes a through hole 31 in the middle and an extension portion 32 surrounding the through hole. The through hole 31 communicates with the central hole 2 . Such as figure 2 As shown, the vehicle pipeline connection joint of this embodiment can be installed in cooperation with the pressure sensor 6 to monitor the pressure change of the mixed gas in the pipeline and prevent leakage.

[0021] Such as figure 1 with figure 2 As shown, the bracket 3 further includes a threaded bush 33 integrally ...

Abstract

The invention discloses a connector for a vehicle pipeline and a vehicle crankcase ventilation pipeline with the connector for the vehicle pipeline. The connector for the vehicle pipeline comprises aconnector body and a center hole. The center hole penetrates through the connector body. The connector for the vehicle pipeline further comprises a support. The support is located in the middle section of the connector body. The support comprises a through hole in the middle and an outer extension portion surrounding the through hole. The through hole communicates with the center hole. The vehiclecrankcase ventilation pipeline comprises the connector for the vehicle pipeline and a pressure sensor. The pressure sensor is installed on the support. The connector for the vehicle pipeline and thepressure sensor can be installed in a matched manner. The vehicle crankcase ventilation pipeline with the connector for the vehicle pipeline can monitor the pressure change of mixed gas in the pipeline, and leakage is prevented.

Description

technical field [0001] The invention relates to the technical field of vehicle crankcase ventilation pipelines, in particular to a vehicle pipeline connection joint and a vehicle crankcase ventilation pipeline including the same. Background technique [0002] When the engine is working, the high-pressure combustible mixture and burned gas in the combustion chamber will leak into the crankcase through the gap between the piston group and the cylinder, causing blow-by. The components of blow-by gas are unburned fuel gas, water vapor and exhaust gas. This will dilute the oil, reduce the performance of the oil, and accelerate the oxidation and deterioration of the oil. Moisture condenses in the oil, forming sludge and clogging the oil passage. The acid gas in the exhaust gas is mixed into the lubrication system, which will cause corrosion and accelerated wear of engine parts; the blow-by gas will also cause the pressure of the crankcase to be too high and damage the seal of th...
