Abstract
The utility model provides an engine exhaust backpressure measuring tool, includes: sensor seat, set up screw and thru hole on sensor seat, through the bolt fastening on sensor seat pressure sensor and pass to the pipe, pressure sensor 1's probe is arranged in the thru hole, pass to tub upper end and close soon through thread head I and be fixed in the thru hole, its lower extreme through thread head II close soon be fixed in the blast pipe on, pressure sensor signal connection in engine ECU. Through in passing to tub the thru hole that gets into among the sensor seat, pressure sensor recorded pressure signal through the probe and feeds back to ECU when the engine combustion gas flow through the blast pipe, testing personnel can through the control computer real -time gather with the change in valuel of control engine exhaust backpressure, made things convenient for on the vehicle data acquisition work to the engine exhaust backpressure greatly. This engine exhaust backpressure measuring tool has small in size, the simple characteristics of installation simultaneously.
Description
Technical field
The utility model relates to survey instrument technical field, is specifically related to a kind of engine exhaust back pressure survey instrument.
Background technology
In vehicle after sale service process, often encounter because vehicle preprocessor carrier subsides or exhaust box damages, cause engine exhaust back pressure excessive, and vehicle is occurred, and engine is difficult to start, or be short of power after starting, the situations such as engine speed fluctuations.Traditional back pressure measuring equipment is adapted at static test engine exhaust back pressure on engine pedestal, is not easy to be assembled on vehicle, the concrete numerical value of dynamic implementing monitoring exhaust back pressure.
Summary of the invention
The utility model in order to overcome the deficiency of above technology, provide a kind of install simple, can the engine exhaust back pressure survey instrument of monitor engines in real time exhaust back pressure situation of change.
The utility model overcomes the technical scheme that its technical matters adopts:
A kind of engine exhaust back pressure survey instrument, comprise: sensor holder, screw and the open-work be arranged on sensor holder, be secured by bolts in the pressure transducer on sensor holder and pass to pipe, the probe of pressure transducer 1 is arranged in open-work, pass to pipe upper end to be screwed by thread head I and be fixed in open-work, its lower end is screwed by thread head II to be fixed on gas outlet, and pressure sensor signal is connected to Engine ECU.
The beneficial effects of the utility model are: by passing in open-work that pipe enters in sensor holder when the waste gas that engine is discharged flows through gas outlet, pressure transducer records pressure signal by probe and feeds back to ECU, testing crew can pass through the numerical value change of monitoring computer Real-time Collection and monitoring engine exhaust back pressure, greatly facilitates the data collection task to engine exhaust back pressure on vehicle.This engine exhaust back pressure survey instrument has compact, installs simple feature simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is installment state structural representation of the present utility model;
In figure, 1. pressure transducer 2. sensor holder 3. bolt 4. screw 5. open-work 6. passes to pipe 7. thread head I 8. thread head II 9. gas outlet.
Embodiment
Be described further below in conjunction with accompanying drawing 1, accompanying drawing 2 pairs of the utility model.
A kind of engine exhaust back pressure survey instrument, comprise: sensor holder 2, be arranged at screw 4 on sensor holder 2 and open-work 5, be fixed on the pressure transducer 1 on sensor holder 2 by bolt 3 and pass to pipe 6, the probe of pressure transducer 1 is arranged in open-work 5, pass to pipe 6 upper end to be screwed by thread head I 7 and be fixed in open-work 5, its lower end is screwed by thread head II 8 to be fixed on gas outlet 9, and pressure transducer 1 signal is connected to Engine ECU.By passing in open-work 5 that pipe 6 enters in sensor holder 2 when the waste gas that engine is discharged flows through gas outlet 9, pressure transducer 1 records pressure signal by probe and feeds back to ECU, testing crew can pass through the numerical value change of monitoring computer Real-time Collection and monitoring engine exhaust back pressure, greatly facilitates the data collection task to engine exhaust back pressure on vehicle.This engine exhaust back pressure survey instrument has compact, installs simple feature simultaneously.
