Description
Technical field
The utility model belongs to engine component field, is related to a kind of Venturi tube assembly with pressure sensor.
Background technology
According to the detection requirement of six regulation of state page 280 J.4.4 vapo(u)rization system：OBD system should monitor the de- of vapo(u)rization system
Attached flow and the integrality for monitoring the entire vapo(u)rization system in addition to pipeline and connector between carbon tank valve and inlet manifold,
To prevent fuel-steam from leaking into air.Should according in J.4.14 to the detection requirement of comprehensive component（Such as circuit continuity, number
It is worth over range, reasonability, functional response etc.）To each component of vapo(u)rization system（Such as valve, sensor）It is monitored.Detection evaporation
The integrality and desorption flow of system realize that each component detection of vapo(u)rization system has become research and development focus.
Invention content
The purpose of this utility model is to provide a kind of Venturi tube assembly with pressure sensor, is meeting the prior art
Under the premise of, start being arranged between carbon tank valve and Venturi tube for the pressure sensor of discharge vaporization, it can be achieved that being pressurized
The monitoring of machine pressure duct part OBD improves emission performance and fuel economy, to save the valuable energy, reduces automobile oil
Gas discharges the pollution to environment, protects the health of people.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of Venturi tube assembly with pressure sensor, including Venturi tube, the canister being arranged in Venturi tube
Valve and discharge vaporization pressure sensor, the upper tube wall of the Venturi tube are provided with pressure sensor installation duct, the evaporation
The pressure sensor probe of discharge pressure sensor be deep into sensor mounting hole the road in and be located at carbon tank valve and Venturi tube it
Between, the stitch of the discharge vaporization pressure sensor is connect with the connector at harness end.
The beneficial effects of the utility model are：
1st, discharge vaporization pressure sensor is arranged between carbon tank valve and Venturi tube, passes through the core of sensor internal
Piece, detects the pressure of engine with supercharger high-pressure side pipeline, and is converted to electric signal and passes to ECU, and supercharging can be achieved by identifying
The monitoring of engine high pressure pipeline portions OBD can make engine management system realize the closed loop fuel management control of system early.
2nd, Automobile emission control is conducive to the harm of health and environmental pollution data convenient for monitoring emission
And environmental protection, the demand for the different clients that are content with very little.
3rd, emission performance and fuel economy are improved, to save the valuable energy, reduces automobile oil gas discharge to environment
The health of people is protected in pollution.
Description of the drawings
Fig. 1 is the partial schematic diagram of the utility model.
Fig. 2 is the side view of the discharge vaporization sensor of the utility model.
Specific embodiment
The technical solution of the utility model is further described below in conjunction with the accompanying drawings, however, it is not limited to this, every
Technical solution of the present invention is modified or replaced equivalently, it, should all without departing from the spirit and scope of technical solution of the present invention
Cover in protection scope of the present invention.
As shown in Figs. 1-2, the Venturi tube assembly provided by the utility model with pressure sensor includes Venturi tube
1st, the carbon tank valve 2 and discharge vaporization pressure sensor 3 being arranged in Venturi tube, the upper tube wall of the Venturi tube 1 are provided with
Sensor mounting hole road, the sensor mounting hole road and the connecting pin of carbon tank valve 2 and Venturi tube 1 are located on same circumference,
The discharge vaporization pressure sensor 3 includes pressure sensor body 4, pressure sensor probe 5, fixing screw hole 6, stitch 7,
The pressure sensor probe 5 is deep into sensor mounting hole road and between carbon tank valve 2 and Venturi tube 1, the pressure
Fixing screw hole 6 is provided on force snesor ontology 4, pressure sensor body 4 is fixed on Venturi tube by fixing screw hole 6
On 1, the stitch 7 is connect with the connector at harness end.
The fixing screw hole 6 of the discharge vaporization pressure sensor 3 is M5 type screw holes.
The discharge vaporization pressure sensor 3 should ensure that pressure port downward when installing, with vertical direction angle 0 ~ ±
It 60 °, is fixed with the screw and mounting surface of M6, is attached by the stitch 7 and the connector at harness end of sensor, harness end
Pairing connector allows for waterproof.
During utility model works, discharge vaporization pressure sensor 3 is arranged between carbon tank valve 2 and Venturi tube 1, is led to
The chip of sensor internal is crossed, detects the pressure of engine with supercharger high-pressure side pipeline, and is converted to electric signal and passes to ECU, is led to
The monitoring that engine with supercharger pressure duct part OBD can be achieved in identification is crossed, engine management system can be made to realize system early
Closed loop fuel management controls.
