Abstract
The utility model discloses a kind of cavaera hair net shells with pressure sensor, the pressure sensor for PCV diagnosis including valve chamber housing ontology and on the valve chamber housing ontology, sensor mounting hole is provided on the valve chamber housing ontology, the pressure sensor probe of the pressure sensor is deep into sensor mounting hole, the stitch of the pressure sensor is connect with the connector at harness end, and the sensor mounting hole is set on PCV pipelines.The utility model will be arranged in valve chamber housing for the pressure sensor that PCV is diagnosed, pass through the chip of sensor internal, detect engine with supercharger crankcase ventilation pressure, and it is converted to electric signal and passes to ECU, the OBD that engine with supercharger Pcv system can be achieved by identification is monitored, and engine management system can be made to realize the closed loop fuel management control of system early.
Description
Technical field
The utility model belongs to engine component field, is related to a kind of valve chamber housing with pressure sensor.
Background technology
According to six regulation of state page 285, J.4.9.1 crankcase ventilation（PCV）System monitoring requirement：If vehicle uses
Pcv system, manufacturing enterprise are monitored Pcv system, it is ensured that system integrity.To the vehicle of no crankcase scavenged control requirement
It does not need to carry out Pcv system monitoring.To ensure the integrality of bent axle ventilating system, energy waste, engine with supercharger PCV systems are reduced
The OBD monitorings of system have become research and development focus.
Invention content
The purpose of this utility model is to provide a kind of valve chamber housing with pressure sensor, is meeting the prior art
Under the premise of, it will be arranged on valve chamber housing for the pressure sensor that PCV is diagnosed, it can be achieved that engine with supercharger Pcv system
OBD is monitored, it is ensured that and the integrality of crankcase ventilation system improves emission performance and fuel economy, to save the valuable energy,
Pollution of the automobile oil gas discharge to environment is reduced, protects the health of people.
The purpose of this utility model is achieved through the following technical solutions：
A kind of cavaera hair net shell with pressure sensor, including valve chamber housing ontology and mounted on the gas
The pressure sensor for PCV diagnosis in door room shroud body is provided with sensor installation on the valve chamber housing ontology
Hole, the pressure sensor pressure sensor probe is deep into sensor mounting hole, the stitch of the pressure sensor with
The connector connection at harness end, the sensor mounting hole are set on PCV pipelines.
The beneficial effects of the utility model are：
1st, valve chamber housing will be arranged in for the pressure sensor that PCV is diagnosed, passes through the chip of sensor internal, inspection
Engine with supercharger crankcase ventilation pressure is surveyed, and is converted to electric signal and passes to ECU, engine with supercharger can be achieved by identification
The OBD monitorings of Pcv system can make engine management system realize the closed loop fuel management control of system early.
2nd, the OBD monitorings of engine with supercharger Pcv system can be achieved, engine management system can be made to realize closing for system early
Ring fuel management controls, it is ensured that the integrality of crankcase ventilation system.
3rd, convenient for pollution of the diagnostic monitoring crankcase emissions to environment, the demand for the different clients that are content with very little.

Cover in the scope of protection of the utility model.
As shown in Figs. 1-2, the cavaera hair net shell provided by the utility model with pressure sensor includes valve cover
Shell ontology 1 and the pressure sensor 2 for PCV diagnosis on the valve chamber housing ontology 1, the valve cover
Sensor mounting hole 4 is provided on shell ontology 1, the pressure sensor 2 includes pressure sensor body 7, pressure sensor
Probe 3, fixing screw hole 5, stitch 6, the pressure sensor probe 3 are deep into sensor mounting hole 4, pressure sensor sheet
Body 7 is fixed on by fixing screw hole 5 on valve chamber housing ontology 1, and stitch 6 is connect with the connector at harness end, the sensing
Device mounting hole 4 is set on PCV pipelines.
The fixing screw hole of the pressure sensor 2 is M5 type screw holes.
The sensor mounting hole 4 is set on the PCV pipelines of inlet port or exhaust port side.
The pressure sensor 2 should ensure that pressure sensor pops one's head in 3 pressure ports downward when installing, with vertical direction angle
It 0 ~ ± 60 °, is fixed, is attached by the stitch 6 and the connector at harness end of sensor, harness with the screw and mounting surface of M5
The pairing connector at end allows for waterproof.
The utility model, which will be arranged on valve chamber housing for the pressure sensor that PCV is diagnosed, it can be achieved that being pressurized, to be started
The monitoring of the OBD of machine Pcv system, it is ensured that the integrality of crankcase ventilation system, convenient for diagnostic monitoring crankcase scavenged substance environment
Pollution, the demand for the different clients that are content with very little.
