Abstract

The invention discloses a diagnosis type crankcase ventilation pipe. The diagnosis type crankcase ventilation pipe comprises a connector, wherein the connector comprises a female connector and a maleconnector, the female connector is connected with the male connector in a clamped mode, an outer connector is arranged outside a connecting position of the female connector and the male connector, anda diagnosis circuit is arranged between the female connector and the male connector and is mutually extruded and communicated when the female connector and the male connector are connected. Accordingto the diagnosis type crankcase ventilation pipe disclosed by the invention, the female connector and the male connector are connected in a clamped mode, meanwhile, the outer connector is used for reinforcing connection, and reliable connection of the connectors is guaranteed; and through arrangement of the diagnosis circuit, the real-time vehicle-mounted detection is realized, when the connectoris loosened, the diagnosis circuit is disconnected, the control unit cannot receive a signal, and an alarm is given.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and more specifically relates to a diagnostic crankcase ventilation pipe. Background technique [0002] In order to prevent excessive crankcase pressure, prolong the service life of engine oil, reduce wear and corrosion of parts, and prevent engine oil leakage, crankcase ventilation must be implemented. In addition, in order to meet increasingly stringent emission requirements and improve economy, crankcase ventilation system design must also be carried out in the automotive engine design process. [0003] In the prior art, the ventilation pipes in the crankcase ventilation system, in order to improve the reliability of the connection and avoid problems such as air leakage, make it difficult to install or disassemble the ventilation pipes, and there is no good on-board testing equipment to detect them. The real-time monitoring of the ventilation pipe often makes it difficult for the user to fin...
