Embodiment
In order to make those skilled in the art understand the technical scheme in the application better, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments. Based on the embodiment in the application, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all should belong to the scope of the application's protection.
For enabling above-mentioned purpose, the feature and advantage of the application more become apparent, below in conjunction with the drawings and specific embodiments, the application is described in further detail.
See Fig. 1, it it is the long-pending carbon removing method schema of the embodiment of the present invention a kind of supercharging blower nozzle blade.
The method is applied to system as shown in Figure 2, this system comprises engine 21, the ECU26 etc. of the variable nozzle supercharging blower 22 that is connected with engine 21, charge air cooler 23, the vacuum pump 25 regulating nozzle blade 24 aperture of variable nozzle supercharging blower, control vacuum pump. Wherein, engine 21 can be diesel motor etc.
This long-pending carbon removing method can comprise:
Step 101, obtains the running status of engine.
The present embodiment can arrange independent monitoring device the running status of engine monitored; Can also in ECU the running status of integrated monitoring assembly monitor sender.
Step 102, judges whether the running status of engine meets cleared condition.
This monitoring device first can judge after the running status obtaining engine whether it meets the cleared condition preset voluntarily, if reporting ECU again. Can also be that the running status of engine is directly reported to ECU by monitoring device, judge whether the running status of engine meets cleared condition by ECU.
This cleared condition can be specifically that engine is in idling operation, also can also be other default conditions certainly, and such as motor speed is less than predetermined threshold value etc., it is also possible to be the combination of multiple condition.
If the running status of engine meets cleared condition, then perform step 103, if not meeting cleared condition, then maintaining the statusquo, not performing step 103.
Step 103, if the running status of engine meets cleared condition, then controls vacuum pump and changes vacuum tightness, the nozzle blade of variable nozzle supercharging blower is swung, with the long-pending carbon removed on nozzle blade.
