Embodiment
In Fig. 1, schematically show internal-combustion engine 10 and this internal-combustion engine 10 is represented with reference character 10 on the whole.This internal-combustion engine 10 has firing chamber 12, supplies combustion airs 16 by suction passage 14 to described firing chamber 12 at this.
The combustion air amount is controlled by means of throttle valve 18.Described throttle valve 18 especially mechanically trigger and in the free-runing operation process of internal-combustion engine 10 with suction passage 14 complete closed.
For the throttle valve of avoiding cutting out fully 18 is provided with first bypass passageways 20, this first bypass passageways 20 is seen in the front and back of described throttle valve 18 along the flow direction of combustion air 16 and is connected with suction passage 14.Described bypass passageways 20 can be opened fully or ends fully by means of valve mechanism 22.
For higher combustion air amount can be provided, this is favourable when the cold starting of internal-combustion engine 10 especially, be provided with second bypass passageways 24, these second bypass passageways, 24 same seeing in the front and back of described throttle valve 18 along the flow direction of combustion air 16 are connected with suction passage 14.Described second bypass passageways 24 can be opened fully or close fully by means of additional valve mechanism 26.
For the position of controlling described valve mechanism 22 and additional valve mechanism 26 is provided with controller 28, this controller 28 loads the signal of pulsewidth modulation to valve mechanism 22 and additional valve mechanism 26.
It is the needed combustion air mass flow rate of the idle running mslls that keeps internal-combustion engine 10 that described controller 28 can be set in advance in when throttle valve 18 cuts out.Because under standard conditions, draw the characteristic curve of described valve mechanism 22 and additional valve mechanism 26 usually, so described combustion air mass flow rate mslls is converted to these standard conditions, method be with mslls divided by factor ftu and fpu, thereby obtain standard combustion air mass flow rate mnlls.Here ftu equals the root of the ratio between standard temperature and the ambient temperature.Factor fpu equals the ratio between external pressure and the standard environment pressure.
Needed mass flow rate mnlls enters into combined characteristic 30 for the free-runing operation of internal-combustion engine 10, and this combined characteristic 30 is made up of with the characteristic curve 34 of additional valve mechanism 26 characteristic curve 32 of valve mechanism 22.Such as can in the state of opening fully, the combustion air mass flow rate of 4kg/h being provided and providing the maximum combustion MAF of 6kg/h by means of adding valve mechanism 26 by means of valve mechanism 22.
Can calculate total dutycycle by means of essential combustion air mass flow rate mnlls and characteristic curve 30, this total dutycycle is divided into the dutycycle talls1 of valve mechanism 22 and the dutycycle talls2 of additional valve mechanism 26.Dutycycle characterizes the time share relevant with the time lag, opens fully at valve mechanism 22 described in this time share or additional valve mechanism 26.
If such as the combustion air amount that needs 6kg/h, this is just corresponding with 133% the numerical value that can obtain from characteristic curve 30 so for the free-runing operation of internal-combustion engine.Be to determine the dutycycle talls2 of described additional valve mechanism 26, from this numerical value, deduct one 100% numerical value and from the numerical value that obtains thus and numerical value 0%, select maximum value.This maximum value is corresponding to the dutycycle talls2 of described additional valve mechanism 26.In addition, from the numerical value of trying to achieve, deduct the numerical value that calculates into described dutycycle talls2 by means of characteristic curve 30.For the illustrated example in front, for talls2 obtains 33% numerical value and is the numerical value of talls1 acquisition 100%.
Can not by beat ground (getaktet) but move described additional valve mechanism 26 (with reference to Fig. 3) as distributing valve.Can especially easily trigger additional valve mechanism 26 thus.The dutycycle talls1 of valve mechanism 22 is that the front is determined with reference to the illustrated this situation of Fig. 2.The dutycycle talls2 of additional valve mechanism 26 has numerical value 0% (additional valve mechanism 26 is closed fully) or has numerical value 100% (additional valve mechanism 26 is opened fully).
For the cold starting of internal-combustion engine 10 and the additional valve mechanism 26 that is configured to distributing valve, this additional valve mechanism 26 is opened fully, that is to say the dutycycle operation with 100%.Extra combustion air amount demand is controlled by the beat (Taktung) of valve mechanism 26.In case necessary combustion air mass flow rate is reduced to one corresponding to can be by means of the numerical value of opening the maximum flow that valve mechanism 22 provides fully for the free-runing operation of internal-combustion engine 10, that just closes described additional valve mechanism 26.
For determining the on off state of additional valve mechanism 26, from the numerical value of trying to achieve, deduct one 100% numerical value by means of characteristic curve 30.Check in the scope of condition 36 whether thus obtained numerical value is positive.In this case, so switch the switching mechanism 38 of additional valve mechanism 26, make and to open (talls2=100%) fully by additional valve mechanism 26.If do not satisfy condition 36, the switching mechanism 38 that just so switches described additional valve mechanism 26 makes additional valve mechanism 26 cut out (talls2=0%) fully.
The dutycycle talls1 of described valve mechanism 22 correspondingly obtains by this mode of dutycycle talls2 that will deduct additional valve mechanism 26 by means of the numerical value that characteristic curve 30 is tried to achieve.
About and structure shown in Figure 1 between common point, below under the situation of reference Fig. 4 with reference to above-mentioned explanation.With by the mode of execution of Fig. 1 different be that the form with the circuit controls valve 40 of fuel tank gas outlet means 42 in by the mode of execution of Fig. 4 is provided with additional valve mechanism 26.
Described fuel tank gas outlet means 42 comprises the filtering mechanism of activated carbon filter 44 forms.Described activated carbon filter 44 is connected with fuel tank 48 by pipeline 46, has stored the fuel that is used for operation of combustion engine 10 in described fuel tank 48.In addition, described activated carbon filter 44 is connected with the gas exhaust piping 50 that opens wide in tip side and is connected with pipeline 52 in importing suction passage 14.
Described activated carbon filter 44 suppresses fuel vapours, but can exhausting air, comes exhausting air by means of gas exhaust piping 50 or rather.
If open circuit controls valve 40, that just can be drawn onto in the suction passage 14 and flow to firing chamber 12 and be used to support combustion process being stored in fuel mass in the active carbon of activated carbon filter 44.
Can be when the internal-combustion engine cold starting with circuit controls valve 40 as additional valve mechanism 26.When temperature was low, activated carbon filter 44 did not discharge the fuel vapour of being stored, thereby opening of circuit controls valve 40 can not cause to the extra fuel of firing chamber 12 conveyings in this state.More definite theory only makes extra combustion air arrive in the firing chamber 12 of internal-combustion engine by opening of circuit controls valve 40.The air quantity of needed increase when can be provided in cold starting in this way forms and do not distort mixture in the mode of not expecting in this case.
Trigger circuit controls valve 40 with reference to Fig. 5 illustrated as following.Necessary standard combustion air mass flow rate mnlls enters into characteristic curve 30 for the free-runing operation of internal-combustion engine 10, thereby reads total value.
The dutycycle talls of described valve mechanism 22 tries to achieve by the dutycycle tatev that the total value that will read from characteristic curve 30 deducts circuit controls valve 40.
Preestablish the dutycycle tatev of described circuit controls valve 40 by controller 28, described controller 28 also is used to control fuel tank vent systems 42.This dutycycle is represented with tate in Fig. 5.Deduct 100% numerical value that obtains in the numerical value that will read if dutycycle tate is higher than from characteristic curve 30, that just comes operating loop control valve 40 with dutycycle tate.Otherwise come operating loop control valve 40 with dutycycle tatev, described dutycycle tatev deducts 100% by the numerical value that will read and determines from characteristic curve 30.
