Description
[technical field]
The utility model relates to a kind of air induction system of injection engine motorcycle.
[background technique]
The start of motorcycle is that the firing chamber with the oil gas input engine after fuel oil and the air mixing fires, and promotes piston and moves reciprocatingly thereby produce power, drives front-wheel and rotates synchronously and promote trailing wheel, to reach the purpose of advancing.And because oil gas perfect combustion fully in the firing chamber, cause remaining oil gas to derive from outlet pipe, and then generation waste gas causes the pollution of air, for this reason, the dealer imports secondary air in outlet pipe, make waste gas burning once more in outlet pipe of engine emissions, reach and reduce the pollution of waste gas air.Known air induction system 1, see also shown in Figure 1, it is air induction system for the Carburetor engine motorcycle, this air induction system 1 has a conduit 11, this conduit 11 is provided with an one-way valve 12, these one-way valve 12 1 ends are to be connected with second air-strainer 13, the other end then is connected to the dummy pipe 22 that is communicated with outlet pipe 21 with ingress pipe 14, the waste gas of engine 2 then is disposed to dummy pipe 22 and enters in the outlet pipe 21, and the air that is imported by the external world is after by second air-strainer 13 and one-way valve 12, and enter in the outlet pipe 21 by dummy pipe 22 through ingress pipe 14, because it is to be a condition of high temperature that engine 21 is discharged the waste gas that contains oil gas, therefore the air that contains oxygen by one-way valve 12, can have the combustion-supporting effect waste gas burning of ordering at oxygen, oil gas in the waste gas is reduced, and reduce the atmospheric pollution that waste gas caused that outlet pipe 21 is discharged.Because the secondary air intake method of commonly using is the negative pressure by outlet pipe 21, to do burning once more in the extraneous secondary air importing outlet pipe 21, when engine running is too fast, can cause the negative pressure of outlet pipe 21 to diminish making the gettering quantity deficiency, and make the waste gas in the outlet pipe can't fully do secondary combustion, and then cause the raising of exhaust emission pollution degree, cause motorcycle its toxic emission when running at high speed can't reach the requirement of environmental regulation.
Because environmental regulation is got over strict, the motorcycle manufacturer has released the injection engine motorcycle that can effectively reduce the exhaust emission pollution degree, injection engine motorcycle is in order to make engine when running up, also can reach the purpose that reduces the exhaust emission pollution degree, the dealer has developed another air induction system 3, see also shown in Figure 2, this air induction system 3 mainly is to establish a secondary air conduit 31 in outlet pipe 4 sides, this secondary air conduit 31 is provided with an one-way valve 32, one solenoid valve (Air Injection Solenoid Value), 33 and one secondary air jar 34, wherein, this outlet pipe 4 is provided with an oxygen sensor 41, this oxygen sensor 41 and solenoid valve 33 be with fuel injection be that the electronic controller (Electronic Control Unit) 5 of system connects, distance and oil mass during these electronic controller 5 may command fuel-injecteds, make nozzle 51 with the press atomization fuel oil, before suction valve, fully mix, when INO, enter combustor inner cylinder again with air.
When engine E after starting, when general rotating speed, being arranged at oxygen sensor 41 on the outlet pipe 4 can continue detecting and discharged oxygen content in the oil gas by engine E firing chamber E1, and signal is sent to electronic controller 5, and the solenoid valve 33 of control air induction system 3 is the states for opening, extraneous secondary air can be imported by secondary air jar 34 and do burning once more in the outlet pipe 4, at this moment, oxygen sensor 41 meeting transmitting signals are to electronic controller 5, and this electronic controller 5 can not listed this signal in the parameter (being so-called BY PASS); And when engine E is in the default state that runs up, even these electronic controller 5 solenoid valves 33 are closing state, at this moment, oxygen sensor 41 can continue the oxygen content in the detecting outlet pipe 4, when the oxygen sensor 41 of outlet pipe 4 detects oxygen content in the outlet pipe 4 when not enough, can transmit signal to electronic controller 5, this electronic controller 5 can transmit a signal control electromagnetic valve 33 and cut out, and send the fuel injection quantity of signal control fuel nozzle 51 simultaneously, adjust air fuel ratio (air/fuel), make fuel oil in the firing chamber of cylinder, do burning more completely, by oxygen sensor 41, solenoid valve 33 and electronic detection device 5 threes' cooperation, can reduce the contaminant capacity of waste gas, to reach the control of the accurate blowdown flow rate of motorcycle.
Though above-mentioned air induction system 3 mainly can be controlled the fuel injection quantity of nozzle 51 by electronic controller 5, make it reach accurate blowdown flow rate, yet, the control ability of this solenoid valve 33 is also very important for accurate blowdown flow rate, therefore how to allow solenoid valve 33 not be subjected to the infringement of dust and water and be damaged, to keep solenoid valve 33 normal control functions, could make the maximum function of these air induction system 3 performances, be the target of motorcycle pursuit that the dealer desires most ardently at present.
