By reading instructions, those of ordinary skills will understand feature and the content of these technical schemes better.
The accompanying drawing explanation
Below by the reference accompanying drawing and in conjunction with example, the utility model is described particularly, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explaining to of the present utility model, and do not form the restriction of going up in all senses of the present utility model, in the accompanying drawings:
The structural representation of the engine exhaust system temperature that Fig. 1 is the utility model the first embodiment or the measurement mechanism of pressure.
The structural representation of the engine exhaust system temperature that Fig. 2 is the utility model the second embodiment or the measurement mechanism of pressure.
The engine exhaust system temperature that Fig. 3 is the utility model embodiment or the measurement mechanism of pressure are installed to the structural representation on exhaust manifold.
Embodiment
As Fig. 1, shown in Fig. 2, the utility model provides the measurement mechanism of a kind of engine exhaust system temperature or pressure, comprise: web member 10, one end is set to through hole nut 12, for the arbitrary sensor connector with on exhaust manifold, is connected, and at least is provided with a sensor crossover sub 11 on the other end; At least one in temperature sensor 30 and pressure transducer 40, be connected with this sensor crossover sub 21, for temperature or the pressure of measuring engine exhaust system.
As wherein the time of the temperature that only needs to measure engine exhaust system and pressure, as shown in Figure 1, only need to arrange a sensor crossover sub 11 on this web member 10, for connecting temperature sensor 30 or pressure transducer 40; When the temperature that need to simultaneously measure engine exhaust system and pressure, as shown in Figure 2, two sensor crossover subs 11 are set on this web member 10, be respectively used to connect temperature sensor 30 and pressure transducer 40.
Referring again to Fig. 3, in the specific implementation, the sensor connector 21 for being connected with web member 10 on above-mentioned exhaust manifold 20 is selected the lambda sensor joint, because when carrying out the long duration test test, the lambda sensor be connected on the lambda sensor joint does not participate in engine system control, more a lot of effects to a sealing are the carrying out that can not affect test so utilize this lambda sensor joint.The M22 WELD NUTS that all adopts standard due to most of producers, as the lambda sensor joint, so the through hole nut 12 on this web member 10 specifically is set to the through hole nut of M22, is connected for the lambda sensor joint 21 with on exhaust manifold 20.If certainly on exhaust manifold 20, have other idle sensor connector also to can be used for being connected with web member 10, now the through hole nut 12 on this web member 10 can be arranged to the corresponding element of the sensor connector idle with this.
Because web member 10 directly is connected with the lambda sensor joint that does not participate in test on exhaust manifold 20 by the through hole nut 12 on it, so when completing all test events, without this exhaust manifold 20 is transformed, the original state that has kept exhaust manifold 20, guarantee that the engine that each is taken one's test takes same test point simultaneously, more be conducive to the analysis to data.
When measuring the temperature of engine exhaust system, can directly be connected on sensor crossover sub 11 by temperature sensor 30; The diameter of above-mentioned sensor crossover sub 11 is less than on exhaust manifold the diameter of 20 sensor connector 21, and in the present embodiment, the diameter of this sensor crossover sub 11 is 3 millimeters.
When measuring the pressure of engine exhaust system, because high-temp pressure sensor 40 can't directly carry out contact measurement as temperature sensor 30.Referring to Fig. 3, in the present embodiment, this sensor crossover sub 11 is direct-connected is capillary tubing 51, if the diameter of this sensor crossover sub 11 is 3 millimeters, the diameter of this capillary tubing 51 is also 3 millimeters.This capillary tubing 51 can not directly be connected with pressure transducer 40 equally, and it need to pass through teflon pipe 53 Bonding pressure sensors 40, that is to say, and the direct Bonding pressure sensor 40 of an end of teflon pipe 53, the other end is connected with capillary tubing 51.But, in general, the diameter of this teflon pipe 53 is greater than the diameter of capillary tubing 51, and the diameter of teflon pipe 53 can be 6～10 millimeters, such as being 8 millimeters etc., so also need to be connected by X-over 52 between this teflon pipe 53 and capillary tubing 51.
As can be seen here, no matter be to the measurement of engine exhaust system temperature or the measurement of pressure, its structure is all very simple, and installs also very convenient.
The utility model provides the measurement mechanism of a kind of engine exhaust system temperature or pressure, and this apparatus structure is simple, easy for installation; Employing is provided with the web member of sensor crossover sub and is connected with the lambda sensor joint on exhaust manifold the measurement that realizes engine exhaust system temperature or pressure.Thereby take full advantage of the lambda sensor joint test generation not affected on exhaust manifold, without exhaust manifold is transformed, the structure of exhaust manifold do not damaged.And because the engine that each is taken one's test is taked same test point, so more be conducive to the analysis of measurement data.
Above with reference to the accompanying drawings of preferred embodiment of the present utility model, those skilled in the art do not break away from scope of the present utility model and essence, can have multiple flexible program to realize the utility model.For example, the feature that illustrates or describe as the part of an embodiment can be used for another embodiment to obtain another embodiment.These are only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalence that all utilization the utility model instructionss and accompanying drawing content are done changes, within all being contained in interest field of the present utility model.
