S1-2, main powering mode test
Main powering mode is meeting unit normal operation and in the range of safety margin, and unit is under each power rating
The highest state of electricity output efficiency, i.e., unit needs the big angle of ignition and big air-fuel ratio under corresponding power, makes to export electrical efficiency most
It is high；
The test changed power gradient of the gas engine is set, according to the test changed power gradient of setting,
The power of the gas engine is successively increased up to the cylinder that the moment observes the gas engine in rated power, test is buckled
Line and gas consumption instrument data, adjusting the angle of ignition and air-fuel ratio makes institute under the secured premise for avoiding the gas engine detonation
It is minimum to state gas engine gas consumption rate, that is, tests the corresponding optimal ignition angle of the gas engine under each power gradient point value
With maximum air-fuel ratio, the angle of ignition of the main powering mode and the two-dimensional table of air-fuel ratio are drawn, the Engine ECU is stored in
It is interior；
S1-3, main heat supply mode test
Main heat supply mode is meeting unit normal operation and in the range of safety margin, and unit is under each power rating
The highest state of thermal output efficiency, i.e., unit needs the small angle of ignition and small air-fuel ratio under corresponding power, makes to export the thermal efficiency most
It is high；
According to the test changed power gradient of setting, the power of the gas engine is successively increased until specified function
Rate, observing the exhaust pipe and row's temperature of the gas Combustion booster in test not surpass safety limit, test each power gradient
The corresponding minimum ignition angle of gas engine and minimum air-fuel ratio under point value, and draw the angle of ignition and sky of main heat supply mode
The two-dimensional table for firing ratio, is stored in the Engine ECU；
Step 2: the activation of main powering mode
S2-1, press the main powering mode button, the Engine ECU detects the main powering mode button conveying
Activation signal after, transfer it is internal prestore in S1-2The two-dimensional table that step is formed；
S2-2, client set the target power value of unit according to actual needs, and be conveyed to the Engine ECU, institute
Stating Engine ECU is made using the target power value received as input quantity by adjusting the aperture of the electronic throttle
The actual power value of unit is consistent with the target power value；
The Engine ECU is inquired and is transferred in S1-2In the two-dimensional table that step is formed, with the actual power value or institute
It states target power value to light a fire accordingly angular dimensions and air-fuel ratio parameter, and according to the igniting angular dimensions and the air-fuel ratio state modulator
Unit operates in optimal gas consumption rate state, enters unit and exports the highest main confession of electrical efficiency under the target power value
Power mode；
Step 3: the activation of main heat supply mode
S3-1, press the main heat supply mode button, the Engine ECU detects the main heat supply mode button conveying
Activation signal after, transfer it is internal prestore in S1-3The two-dimensional table that step is formed；
S3-2, client situation is actually needed according to heat and sets target temperature value, and be conveyed to the Engine ECU, it is described
Engine ECU also reads the parameter of the temperature sensor in real time, knows the reality of the waste-heat recovery device output end of hot water
Temperature value, and the temperature gap between the actual temperature value and the target temperature value is calculated, the Engine ECU is to calculate
Temperature gap based on the electronic throttle is adjusted, realize that the power adjustment of unit, the Engine ECU are known
After the actual motion power of the gas engine, is transferred according to the actual motion power and inquire the S of storage inside1-3Step
The two-dimensional table of formation, and according to igniting angular dimensions corresponding in the table and air-fuel ratio parameter, it adjusts and control unit is upper

Engine ECU controls the waste heat electronic bypass valve and closes, and the waste heat bypass pipe cut-off ran the gas engine
Intercooler described in journey, the flue gas heat-exchange unit and the Heat Exchanger in Circulating Water System recycle heat exchanger tube with the corresponding waste heat respectively
Heat exchange is carried out, realizes that waste heat all recycles；Under above-mentioned working condition, the hot water outlet temperature value of the waste-heat recovery device is also
It is less than the target temperature value, client needs to increase additional heat source and carries out heat supplement；
S2-5, when the hot water outlet temperature value of the waste-heat recovery device be greater than the target temperature value when, the engine
ECU controls the waste heat electronic bypass valve and opens, by the waste heat bypass pipe by a part of unit tail in the exhaust pipe
Gas is fed directly to the exhaust gas treating device, reduces the flue gas heat-exchange unit heat exchange efficiency, until the waste-heat recovery device
Hot water outlet temperature value is consistent with the target temperature value.
The S as a preferred technical solution,3-2In step, the Engine ECU is based on the temperature gap calculated
The specific method being adjusted to the electronic throttle is,
S3-3, the temperature gap is when being negative value, the Engine ECU judges that the gas engine needs to improve power,
The aperture that the Engine ECU controls the electronic throttle increases, and increases the gas engine air inflow, and power increases
Greatly, excess heat increases, and reduces the difference between the actual temperature value and the target temperature value, until the two is equal；
S3-4, the temperature gap is when being positive value, the Engine ECU judges that the gas engine needs to reduce power,
The aperture that the Engine ECU controls the electronic throttle reduces, and reduces the gas engine air inflow, power drop
