Abstract
The utility model discloses a calibration instrument of a synthetic parameter tester for engines. The utility model is characterized in that the utility model comprises a speed regulation motor, a rotary disc, an electricity distributor, a spark plug, a high-voltage pulse generator and a display instrument; the output end of the speed regulation motor, the front side of the rotary disc, the back side of the rotary disc and the front end of the electricity distributor are connected through couplers; the back end of the electricity distributor and the spark plug are connected through a high-voltage ignition line; the high-voltage pulse generator is connected with the back end of the electricity distributor through a conducting wire. The utility model completely simulates the signal of the rotation speed of the engine, conforms to the uniform principle of test and use, and has accurate calibration and simple operation.
Description
The utility model relates to the measurement instrument that is used to detect with adjustment engine comprehensive parameter tester.
The engine comprehensive parameter tester is under the situation that engine does not disintegrate, and by its multiple parameter detecting being carried out a kind of instrument of performance evaluation and fault diagnosis, in order to ensure its accuracy, must regularly carry out measurement verification to it.Owing to lack corresponding metering and measuring equipment in the prior art, make the staking-out work of engine comprehensive parameter tester be difficult to carry out, manufacturer and metrological service rely on electronic device with in the signal direct input circuit or rely on motor car engine as factory inspection test or measurement verification means.The method of this direct input electrical signal has got around the measurement of sensor, has run counter to calibrating and has used corresponding to principle.And engine is the source that various parameters constantly change, and it also is inappropriate coming the calibrating instrument parameter as standard.
The purpose of this utility model is: a kind of engine comprehensive parameter tester marking apparatus is provided, and energy is the tach signal of simulated engine fully, and meets calibrating and use one principle mutually, and it is accurate, simple to operate to demarcate.
The technical solution of the utility model is: a kind of engine comprehensive parameter tester marking apparatus is characterized in that: comprise buncher, rotating disk, ignition distributor, spark plug, high-voltage pulse generator and Displaying Meter; Be connected by shaft joint between the rear side of the output terminal of described buncher and the front side of rotating disk, rotating disk and the front end of ignition distributor; Be connected by high-pressure ignition wire between the rear end of described ignition distributor and the spark plug; Described high-voltage pulse generator is connected with the rear end of described ignition distributor by lead; Described Displaying Meter is connected with described ignition distributor by lead.
Above-mentioned calibration device, its ignition distributor, high-pressure ignition wire and spark plug have constituted the firing system of engine together.By regulating the buncher of this marking apparatus, can make motor be in different rotating speed states, because the effect of shaft joint, the also run-in synchronism of rotating disk and ignition distributor, the rotation of ignition distributor has driven the closed and disconnection of its inner circuit breaker, will produce the high-voltage pulse ignition signal, its Displaying Meter is sampled to this signal and is handled the tachometer value that just can obtain engine.On the one hand, marking apparatus shows as standard signal tach signal on Displaying Meter; On the other hand, utilize the engine comprehensive parameter tester to measure the tachometer value of synchronization, by relatively just obtaining the tachometric survey error of indication of engine comprehensive parameter tester.When using this marking apparatus to demarcate engine speed, the speed probe of engine comprehensive parameter tester can be installed on the relevant position of marking apparatus and do as a whole the demarcation, this just meets calibrating fully and uses corresponding to principle, thereby has guaranteed the accuracy of demarcating.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of an exemplary embodiments of the utility model marking apparatus;
Fig. 2 is the vertical view of marking apparatus shown in Figure 1.
Engine comprehensive parameter tester marking apparatus as depicted in figs. 1 and 2 comprises buncher 3, rotating disk 5, ignition distributor 6, spark plug 9, high-voltage pulse generator 10 and Displaying Meter 11; Be connected by shaft joint between the front end of the front side of the output terminal of described buncher 3 and rotating disk 5, the rear side of rotating disk 5 and ignition distributor 6; Be connected by high-pressure ignition wire 12 between the rear end of described ignition distributor 6 and the spark plug 9; Described high-voltage pulse generator 10 is connected by the rear end of lead with described ignition distributor 6; Described Displaying Meter 11 is connected with described ignition distributor 6 by lead.
In the present embodiment, buncher 3 is furnished with speed regulator 2, connects by lead between the two.
The speed probe of the tested instrument of 7 expressions among the figure, in the present embodiment, this sensor clip is contained on the high-pressure ignition wire 12 of marking apparatus; 1 expression support, all parts all directly or indirectly are fixed on the support; 4 and 8 is support, and support 4 is used to support parts such as buncher 3, rotating disk 5 and ignition distributor 6, and support 8 is used to support spark plug 9.
Rotating disk 5 in the present embodiment has two effects, and the one, as the dish of tracing to the source of tach signal, the 2nd, its end face is carved with the rotation number of degrees, can carry out the calibrating of ignition advance angle.
