The high pressure common rail electric-controlled engine high pressure components test unit of one of the present utility model, compared with prior art, there is following beneficial effect: test ECU sends the instruction improving or reduce electric-control motor rail pressure to Engine ECU, Engine ECU controls the rail pressure lifting of electric-control motor according to instruction, electric-control motor rail pressure is exported to test ECU by rail pressure sensor, simultaneously, timer record electric-control motor rail pressure lifting time, test ECU according to judging electric-control motor high voltage component whether fault writing time, and controls warning device and reports to the police.The utility model can when without the need to disassembling electric-control motor, and test electric-control motor high voltage component whether fault, less to the damage of electric-control motor rapidly, in addition, use electrical control, detect accurately high, easy to connect, structure is simple, is suitable for applying on a large scale.
Accompanying drawing explanation
Fig. 1 is the structural representation of specific embodiment of the utility model.
In figure, 1, electric-control motor; 2, rail pressure sensor; 3, warning device; 4, Test Switchboard.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is elaborated, and following examples are to explanation of the present utility model, and the utility model is not limited to following embodiment.
As shown in Figure 1, the high pressure common rail electric-controlled engine high pressure components test unit of one of this programme, comprises electric-control motor 1.One test ECU is connected with an Engine ECU by CAN, Engine ECU is connected with electric-control motor 1, test ECU sends the instruction of raising or reduction rail pressure setting value to Engine ECU, and Engine ECU controls the rail pressure lifting of electric-control motor according to the instruction received.One rail pressure sensor 2 is arranged on electric-control motor 1, for detecting the rail pressure of electric-control motor 1, and the rail pressure value collected is transferred to test ECU.Test ECU also records electric-control motor 1 rail pressure lifting time timer with one is connected, and it is inner that timer is arranged on test ECU.Timer comprises first timer of record electric-control motor 1 rail pressure rise time and records second timer of electric-control motor 1 rail pressure fall time.Test ECU also connects a warning device 3, and warning device 3 can be phonetic alarm or pilot lamp, and when test ECU detects electric-control motor high voltage component fault, warning device 3 is reported to the police, and to remind staff, improves maintenance efficiency.For convenience of test, test ECU also connects the Test Switchboard 4 of a control.
High pressure rail pressure value P1, low pressure rail pressure value P2, the rail pressure rise time t01 of normal system, rail pressure t02 fall time of normal system is preset with in test ECU.
The working method of the proving installation of this programme is:
When testing beginning, ECU will be tested, rail pressure sensor 2 is connected in electric-control motor 1 and Engine ECU, press Test Switchboard 4, first test ECU sends the instruction improving rail pressure setting value to Engine ECU, Engine ECU is according to instruction, current for electric-control motor 1 rail pressure is risen to the high pressure rail pressure value P1 set in test ECU, rail pressure sensor 2 detects rail pressure value and exports to test ECU, first timer record is risen in test ECU by current rail pressure and sets high pressure rail pressure value P1 required time t1 simultaneously, and this rail pressure rise time t1 is transferred to test ECU, then, test ECU sends the instruction reducing rail pressure setting value to Engine ECU, Engine ECU is according to instruction, current for electric-control motor 1 rail pressure is reduced to the low pressure rail pressure value P2 set in test ECU, rail pressure sensor 2 detects rail pressure value and exports to test ECU, simultaneously the second timer record is dropped in test ECU by current rail pressure and sets low pressure rail pressure value P2 required time t2, and this rail pressure t2 fall time is transferred to test ECU, rail pressure rise time t1, rail pressure t2 fall time compare with rail pressure t02 fall time with the rail pressure rise time t01 of normal system by test ECU, as rail pressure rise time t1 is comparatively large and rail pressure t2 fall time is less, then illustrate that the high voltage component of electric-control motor 1 breaks down, now, warning device 3 is reported to the police, and operating personnel answer shutdown maintenance.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
