The fuel feeding of cylinder 3 is undertaken by nozzle 30, and their adjustment is implemented by lead 31 from first output terminal 32 of electronic control unit 38.The output terminal 34 that on the input end 37 of electronic control unit 38, connects electronic control unit 33 by lead 36.This control unit 33 is provided with operating mechanism, and it is designed to accelerator pedal 35 in the present embodiment.The electric connection 39 of electronic control unit 38 links together by the electric connection 41 of bus 40 with incoming mixture pipeline section 8.
Incoming mixture pipeline section 8 has a compressed air joint 42, and it is connected with the outlet connection 44 of compression gas tank 45 by pipeline 43.The air connector 46 of compression gas tank 45 is connected on the compressed air joint 48 of air compressor 49 by pipeline 47.In pipeline 47, pack into pressure governor 50 and air drier 51.Air compressor 49 has an air-breathing adapter 52 that is provided with air filter 53.The axle 54 of air compressor 49 is connected with the main shaft 56 of turbo-charged diesel by belt drive 55.
Fig. 2 represents incoming mixture pipeline section 8 in detail, and it is designed to tubulose and first end joint 10 is arranged and the second end joint 9, has the inner chamber 57 of a circular cross section between them.Inner chamber 57 is centered on by wall 58, supports and pass the axle 59 of valve 60 therein.Valve 60 is inner chamber 57 separated into two parts, that is at the exhaust chamber 62 of inflow chamber 61 that forms between first end joint 10 and the valve 60 and formation between the second end joint 9 and valve 60.Valve 60 position of that close an and standard-sized sheet is arranged and between them position arbitrarily, they are adjusted by rotatingshaft 59.In the present embodiment, regulating device 66 is designed to motor and is equipped with electric regulating device input end 74 and output terminal 65, and they correspondingly are connected with the joint of the bus 40 of electronic control unit 38.Regulating device 66 is by 74 power supplies of regulating device input end.Take out the signal of relevant valve 60 positions from output terminal 65.Pressurized air inflow entrance 67 of design is equipped with the compressed air joint 42 of flow regulator 68 to be attached thereto in the wall 58 between the second end joint 9 and valve 60.Flow regulator 68 also has a complete shut-down position.There is the electric control input end 69 of the flow regulator 68 of a valve 70 to be connected with the bus 40 of electronic control unit 38.
Similarly, on the bus 40 of electronic control unit 38, be fastened on the pressure transducer 72 on the wall 58 output terminal 71, extend to the pressure meter 73 that pressure transducer 72 pressure meters 73 in incoming mixture pipeline section 8 exhaust chambers 62 and pressure transducer 72 are fixed on a similar joint 71 on the wall 58 and extend to the pressure transducer 72 in the inflow chamber 61.
The working method of device 1 is as follows: turbo-charged diesel is supplied with incoming mixture by sucking pipe 4, house steward 5, incoming mixture pipeline section 8, pipeline 11, charger-air cooler 13, pipeline 15, turbocompressor 17 and air filter 19 when invariablenes turning speed.Waste gas leaves cylinder 3 by outlet pipe 27, exhaust manifold 26, exhaust gas turbine 23 and flue gas leading 29.
When the driver pressed accelerator pedal 35 soon in order to increase moment of torsion or engine speed rapidly, turbo-charged diesel 2 needed more multiple fuel and Geng Duo incoming mixture.Additional fuel oil imports in the cylinder 3, but the increase of the fresh mix tolerance that is provided by exhaust-gas turbocharger 22 is still not enough.The pressure of incoming mixture is also lower, and the pressure in the inner chamber 57 is measured by pressure meter 73 constantly and transmitted to electronic control unit 38 from pressure transducer 72.At these working state valve 60 standard-sized sheets.Electronic control unit 38 confirms that the increase of pressure in the inner chambers 57 is rapid inadequately, and the supercharging air that should implement to add by the control program regulation.
In the time should beginning supercharging air, control program has the predetermined data relevant with condition.Rotate and the pressurized air supercharging is discharged in the exhaust chamber 62 from compression gas tank 45 towards closing direction at valve 60 at the beginning.By the endurance of control program regulation supercharging air, control program is considered pressure reduction and the absolute pressure that is recorded by pressure meter 73 equally.
The mode of travelling that the long-distance car driver of any occupation or motor bus driver have him, the average accekeration of expectation, he uses the shifting points of retarder regulation, can determine, stores and draft the retarder eigenvalue.This software application of implementing in the calculating equipment of electronic control unit 38 and handling at the endurance by being used for supercharging air and valve is at electronic control unit 38.Should prevent from too much to consume the air of compression gas tank 45 by software, otherwise the brake Security is brought negative effect, because compression gas tank 45 is constituent elements of whole compressed air system, wherein the most important parts with regard to Security is a braking system.However, when auxiliary the acceleration, do not allow sudden change.
This purpose reaches in principle like this, that is, make endurance of supercharging air and valve handle the frequency that is adjusted into driver's expectation by control software and adapt.Thus air consumption is remained in the predetermined range, but in the endurance of supercharging air, flip-flop does not take place.Thereby avoid the driver when auxiliary the acceleration, to stipulate a kind of undesirable change, that is reduce.
