Description
Technical field
the present invention relates to a kind of control gear of gas engine combustion gas charge flow rate, particularly relate to a kind of gas engine combustion gas air inlet by-pass collar.
Background technique
gas engine is compared with diesel engine, petrol engine, and cleaning, environmental protection are the desirable power generating equipments of industry such as power station, gas station, colliery more.Its burning control mode mainly contains two kinds: a kind of is to adopt manually control; Manually control when another kind has been machine, play machine success back and adopt control automatically.Along with the development of control technique, the existing latter that adopt more.Its control procedure is: air and combustion gas get in the mixer after through valve separately and mix, and again by turbocharger supercharged, are assigned to then in the middle of each cylinder.Generally, the aperture of air valve is fixed, through the aperture of control gas valve regulate empty so than.When the machine of rising (lambda sensor does not have work), need the aperture of manual tune fuel valve, after successfully playing machine lambda sensor proper functioning, the aperture of gas valve is come control automatically according to the signal that lambda sensor feeds back to ECU.Wherein lambda sensor is installed in the outlet pipe; Judge that according to oxygen concentration in the waste gas of burning back air fuel ratio is below or above chemically correct fuel; Come the accurately aperture size of control gas valve; Change the concentration of mixed gas, air fuel ratio be strict controlled near the very narrow scope the chemically correct fuel guaranteeing, make motor can be normally, work efficiently.
The shortcoming of
existing technology is: under the situation that existing technology is constant at gas concentration or fluctuation is very little, can realize automatic control.But in practice, gas concentration and pressure fluctuate at any time, and in CMM Power Generation, combustion gas (gas) concentration and pressure surge are particularly evident.
when source of the gas concentration, when pressure is constant, in the process of the machine of rising, control system is controlled the aperture of fuel valve according to preset parameters; When source of the gas constantly changes, just need constantly reset fuel valve aperture parameter.Owing to be equivalent to idle running during the gas engine starting; Load is very little, the gas quantity of need supplying with seldom, but the size of gas control valve is the demand design of combustion gas during according to the motor proper functioning; This just causes controlling small flow with a large diameter valve; The regulation range of fuel valve is less, needs trace, frequently changes Control Parameter, and gas engine plays very difficulty of machine.
Summary of the invention
the objective of the invention is to solve existing gas engine and play machine difficult technologies problem; A kind of gas engine combustion gas air inlet by-pass collar is provided; The real-time change of this device can well adapt to motor when playing machine gas concentration and pressure, solve source of the gas change cause play the machine difficult problem.
the objective of the invention is to realize through following technical proposal: gas engine combustion gas air inlet by-pass collar; Comprise controller, mixer, admission line, gas control valve and air shut-off valve; Wherein mixer is by controller control operation, and mixer one end connects the gas inlet pipe road, and the other end is connected with the air inlet end through air shut-off valve; Gas control valve is arranged on the flow that is used to control combustion gas on the admission line; Comprise a by-pass line, by-pass line is communicated with the admission line at gas control valve two ends, and by-pass line is provided with the bypass valve of a control gas flow.
in such scheme, said bypass valve diameter is less than the diameter of gas control valve.
are in such scheme; Said mixer rear end is connected with turbosupercharger; The turbosupercharger rear end connects each cylinder, and the end that inblock cylinder goes out gas is provided with lambda sensor, and lambda sensor detects the oxygen concentration of discharging in the gas and numerical value is transferred to controller.
in such scheme, said bypass valve is manually-operable, and gas control valve is by controller control operation automatically, and bypass valve is merely use when starting shooting.
Can find out from each item technical characteristics of the present invention, the invention has the advantages that:
1, this device adopt the less bypass valve of diameter when the machine of rising, after the machine of rising success, adopt the bigger gas control valve of diameter, have made machine operation simple, and automaticity is high; The real-time change that 2, can adapt to gas concentration, pressure has solved source of the gas and has changed a machine difficult problem that causes.
Description of drawings
The present invention will explain through embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a control principle schematic representation of the present invention;
Reference character wherein: the 1st, controller 2 is that mixer 3 is admission lines
The 4th, gas control valve 5 is that air shut-off valve 6 is by-pass lines
the 7th, bypass valve 8 are that turbosupercharger 9 is that cylinder 10 is lambda sensors.
Embodiment
are done further explanation below in conjunction with accompanying drawing to the present invention.
The gas engine combustion gas air inlet by-pass collar that
are as depicted in figs. 1 and 2; In order to have solved the problem of machine difficulty; The present invention is provided with the less fuel bypass valve of diameter between mixer and gas control valve; According to the aperture of gas pressure, concentration adjustment fuel bypass valve, solved the difficulty that causes with large-diameter valve gate control small flow during the machine of rising.
