X6, Y6, Z6 represent to adjust the variable quantity of the valve opening of valve.
The program of engine control is described below with reference to Fig. 2.
At first, after the engine start (S1), calculate the load variation amount (S2) of time per unit.This load variation amount is engine loading variable quantity (increment rate of engine loading).Whether ratio is as 20% little (S3) then to judge load variation amount, when load variation amount than 20% hour, the engine loading (S4) that calculates just.Then carry out the comparison (S5) of present engine loading and safe load (for example maximum output 70%), when than allowing load hour, employing is at fuel flow rate control diagram, ignition timing control diagram and the revolution control diagram corresponding with low NOx shown in Fig. 3 a, Fig. 4 a and Fig. 5 a, according to each chart control fuel flow rate, ignition timing and revolution control.Satisfy the requirement of high efficiency (low fuel expense), low NOx by the control at this interval.
In contrast, in S3, when load variation amount is bigger than 20%, the rapid load change of this regulating and controlling device prediction.In addition,, in S5, allow the load size, the rapid load change of the same prediction of this air bells conditioner at present engine loading ratio though load variation amount is littler than 20%.
For this rapid load change as mentioned above, as long as use the control diagram corresponding, follow the tracks of just difficulty with low NOx.
In the present embodiment, in S3, when load variation amount is bigger than 20%, though or load variation amount is littler than 20%, in S5, allow the load size at present engine loading ratio, in order to follow the tracks of the load change of predicting thereafter really, and adopt shown in Fig. 3 b, Fig. 4 b and Fig. 5 b with corresponding fuel flow rate control diagram, ignition timing control diagram and the revolution control diagram of height output, control (S7) according to each chart control fuel flow rate, ignition timing and revolution.The control of S6 and S7 is not as long as motor stops just to proceed (S8).
The computer program of the load variation amount in S2 then is described.
This load variation amount is calculated compressor horsepower (engine loading) according to the refrigerant pressure and temperature in the entry and exit of the compressor 16 that for example detected at interval in 1 second, calculates the power variation between 1 second then.But not limited by this, also can test example as in repeatedly (for example 5 times) at the refrigerant pressure and temperature of compressor 16, according to for the first time and the refrigerant pressure and temperature calculation engine load of the suction side of the compressor 16 of the 5th and discharge side, obtain load variation amount then again.
Above-mentioned refrigerant pressure and temperature is detected with the pressure detector 202A and the Temperature Detector 202B that are provided on the refrigerant discharge tube 16b by pressure detector 201A on the refrigerant suction pipe 16a that sets compressor shown in Figure 1 16 and Temperature Detector 201B respectively.
At first obtain the load of motor according to (1) formula.Motor output is equivalent to engine loading, and the compressor input is equivalent to compressor horsepower.
The input of motor output=compressor
