Embodiment
Below, a preferred mode of execution of the present invention is described with reference to the accompanying drawings in detail.
As shown in Figure 1, motor (being diesel engine in the present embodiment) 1 comprises cylinder (inflator) 2, cylinder head 3, piston 4, intakeport 5, relief opening 6, Aspirating valves 7, outlet valve 8 and sparger (fuel injection system) 9 etc.Firing chamber 10 is formed, from sparger 9 to firing chamber 10 inner direct fuel in the space divided by cylinder 2, cylinder head 3 and piston 4.Intakeport 5 is connected with air suction way (sucking pipe) 11, and relief opening 6 is connected with exhaust passageway (outlet pipe) 12.
The stop control of present embodiment possesses: suction throttling valve (air inlet shutter) 13, can openedly and closedly be arranged in air suction way 11, can close in air suction way 11; And control mechanism (hereinafter referred to as ECU) 14, control suction throttling valve 13.
The suction throttling valve 13 of present embodiment is the valve of butterfly.Suction throttling valve 13 has: valve (valve body) 15, can close air suction way 11 and be configured in air suction way 11 interiorly; And drive the driver (motor etc.) 16 of valve 15.
ECU14 reads the operating condition of motor 1 from various sensor class, according to the operating condition of this motor 1, controls suction throttling valve 13 with the aperture making the aperture of suction throttling valve 13 become regulation.As the sensor class, comprise the Measuring opening mechanism (valve opening sensor) 19 etc. to engine rotation sensor 17, the accelerator open degree sensor 18 of detection accelerator open degree and the aperture of detection suction throttling valve 13 (valve 15) that the rotating speed of motor 1 detects, the checkout value of these each sensors is transfused to ECU14.
Suction throttling valve 13, when the usual running of motor 1, is controlled the aperture of the regulation for obtaining the suction air quantity corresponding with the operating condition of motor 1 by ECU14.
In addition, ECU14, when making engine stop, in order to the motor 1 when suppressing engine stop vibrates, controls suction throttling valve 13 and closes in air suction way 11 to make valve 15.
Below, the action of the suction throttling valve 13 when utilizing Fig. 2 and Fig. 3 that engine stop is described.
As shown in Figure 3, if ignition key 20 becomes the cut-off S1 of t0, Fig. 2 (moment) from conducting, then ECU14 stops being sprayed to the fuel in firing chamber 10 by sparger 9, and control suction throttling valve 13 and become regulation aperture (aperture o1) near full cut-off fast to make suction throttling valve 13 (valve 15), and with not using filter by suction throttling valve 13 quick closedown to the regulation aperture o1 near full cut-off the S2 of t1, Fig. 2 (moment).
Then, ECU14 confirms whether valve 15 is stabilized in the regulation aperture o1 (whether the aperture of suction throttling valve 13 becomes the regulation aperture o1 near full cut-off) (S3 of Fig. 2) near full cut-off.
In the present embodiment, ECU14 is according to the aperture of the suction throttling valve 13 detected by valve opening sensor 19, being judged to not have the overshoot of valve 15 and undershoot, the aperture of suction throttling valve 13 (valve 15) is when converging on the regulation aperture o1 near full cut-off, is judged as that valve 15 is stabilized in the regulation aperture o1 (aperture of suction throttling valve 13 becomes the regulation aperture o1 near full cut-off) near full cut-off.
And, if ECU14 is judged as that valve 15 is stabilized in the regulation aperture o1 (aperture of suction throttling valve 13 becomes the regulation aperture o1 near full cut-off) near full cut-off, then control suction throttling valve 13 and become full cut-off with roughly certain speed lentamente to make suction throttling valve 13 (valve 15), more lentamente by the suction throttling valve 13 full cut-off S4 of t2, Fig. 2 (moment) till the regulation aperture o1 using filter to compare near full cut-off.
Here, the regulation aperture o1 near above-mentioned full cut-off is set to following aperture: the valve body 15 of overshoot and undershoot does not impact with the limiter in the internal face of air suction way 11 or air suction way 11 repeatedly.
In the present embodiment, when making engine stop, by by the regulation aperture o1 near suction throttling valve 13 quick closedown to full cut-off, the air in air suction way 11 can be cut off rapidly, and the burning reduced rapidly in firing chamber 10, engine speed can be made to reduce fast (with reference to Fig. 3).Therefore, it is possible to effectively suppress the motor 1 during engine stop to vibrate.
In addition, in the present embodiment, do not make suction throttling valve 13 with fast speed full cut-off, and make suction throttling valve 13 temporarily stop at regulation aperture o1 near full cut-off, and by suction throttling valve 13 from the regulation aperture o1 near full cut-off to becoming full cut-off, compare near full cut-off regulation aperture o1 close more lentamente, the impact of the valve 15 of suction throttling valve 13 can be avoided thus.
Above, according to the present embodiment, when making engine stop, control suction throttling valve 13 to make the regulation aperture o1 near suction throttling valve 13 quick closedown to full cut-off, when the aperture of suction throttling valve 13 becomes the regulation aperture o1 near full cut-off, in order to not produce excessive impact when suction throttling valve 13 is closed in air suction way 11, and control suction throttling valve 13 with making suction throttling valve 13 become full cut-off, close more lentamente till comparing the regulation aperture o1 near full cut-off, the suppression that motor 1 when can take into account engine stop thus vibrates, prevent with the impact of the valve body 15 of suction throttling valve 13.
Above, the preferred embodiment of the present invention is illustrated, but the present invention is not limited to above-mentioned mode of execution, and other various mode of executions can be adopted.
