Under the different load of engine, microcontroller 15 measures the revolving speed of engine by speed probe 14, passes through
The aperture of the throttle position of the aperture measurement high pressure fuel pump 11 of actuator 12, actuator 12 is 0-100%, and aperture is bigger, generation
Table throttle position is bigger, and the fuel delivery of high pressure fuel pump 11 is bigger, revolving speed and combustion of the microcontroller 15 (i.e. ECU) according to engine
Oil pump throttle position calculates the aperture for air throttle 3 of offering advice, and the aperture of air throttle 3 is 0-100%, and aperture is bigger, natural gas flow
Amount is bigger, and microcontroller 15 outputs signal to electronic throttle 3 and then controls 3 aperture of electronic throttle, and then can control day
The ratio of right gas and diesel oil.
Debugging and control explanation of the invention: when engine is run, there are two types of operational mode, manual modes for microcontroller 15
And automatic mode, in a manual mode, the aperture of electronic throttle 3 is manually entered by controller 15 to control.In automatic mode
Under, the aperture of electronic throttle 3 is automatically controlled by microcontroller 15, and microcontroller 15 is believed according to engine speed and throttle position
It number controls.Manual mode is mainly used for the engine tune-up stage, and engine tune-up has got well microcontroller 15 and has been switched to automatic mold
Formula.
The debugging process of engine is illustrated with QTA3240 dual fuel engine.
QTA3240 dual fuel engine parameter: cylinder diameter 170mm, stroke 195mm, discharge capacity 53L, twin-six, idling
700r/min, rated speed 1500r/min, rated power 1600KW.
When QTA3240 dual fuel engine is debugged, it is switched to manual mode on the display 16, starts engine, passes through
Engine speed is set as rated speed 1500r/min by display 16, by Dynamometer Control engine output, respectively
Control engine power is the 0%, 25%, 50% of rated power, 75%, 100%, i.e. 0KW, 400KW, 800KW, 1200KW,
1600KW。
When engine output is 0KW, it is manually entered the aperture of electronic throttle 3, electronics section on the display 16
The aperture of valve 3 is 0-100%, and the aperture of input electronic throttle 3 gradually increases from small to large when debugging, electronic throttle 3
Aperture it is bigger, the flow of natural gas is also bigger, and under identical load, the consumed flow of natural gas is bigger, the consumption of diesel oil
Amount is just smaller, passes through the ratio of aperture adjustment the control natural gas and diesel oil of electronic throttle 3.By inputting electronic throttle 3
Aperture gradually increase, gas discharge gradually increases, and diesel oil flow gradually reduces, when the aperture of electronic throttle 3 increases to
When some value, the very little of diesel stream quantitative change, diesel oil flow is not easy the compression ignition in cylinder, engine speed start to fluctuate it is unstable,
The aperture that gradually reduce electronic throttle 3 at this time records electronic throttle 3 until engine peed stable at this time
Aperture is M1, and the aperture of actuator 12 is L1.
In 25%, 50%, 75%, 100% load (i.e. 400KW, 800KW, 1200KW, 1600KW), with identical side
To debugging, the aperture for recording electronic throttle 3 is respectively M2, M3, M4, M5, and the aperture of actuator 12 is L2, L3, L4, L5.
On the display 16 there are two table, table 1 indicates revolving speed, the aperture of actuator 12 and the aperture of electronic throttle 3
Unit and value range, table 2 indicates electronic throttle of engine when different rotating speeds and different 12 apertures of actuator
3 aperture, the revolving speed (X) 1500 when filling in debugging on table 2,12 aperture of actuator (Y) M1, M2, M3, M4, M5, electronics section
Valve opening (Z) L1, L2, L3, L4, L5.
Table 1
| Revolving speed (r/min) | X | 0-10000 |
| Actuator aperture (%) | Y | 0-100 |
| Electronic throttle aperture (%) | Z | 0-100 |
Table 2
After debugging, it is set as automatic mode on the display 16, under automatic mode, the aperture of electronic throttle 3 is
It automatically controls, electronic throttle 3 controls aperture by interpolation method according to the data of table 2, and then controls natural gas and diesel oil
Ratio, reach optimal fuel oil substitution rate.
It should be noted that revolving speed is fixed rotating speed when engine is used for generating set, it is only necessary to be lowered in rated speed
Examination, when engine is for other purposes, engine speed is variation, at this moment needs to debug the multiple revolving speed points of setting.
