Description
Technical field
The utility model relates to a kind of engine controlling unit, especially relates to a kind of engine air inlet tube butterfly-valve controller of controlling air input of engine by air.
Background technique
China's utility model patent 200520016071.7 discloses a kind of microcomputer control gas internal-combustion engine, and be characterized in: the air cylinder of gas supply system is connected successively with solenoid valve, automatically controlled evaporation filter regulator, fuel injection electromagnetic valve, the intake manifold of gas internal-combustion engine, the firing chamber of gas internal-combustion engine, outlet pipe, three-way catalytic converter; The heating chamber of the automatically controlled evaporation filter regulator of water circulation system is communicated with the cooling jacket of gas internal-combustion engine by pipeline; The input end of Control System of Microcomputer respectively with air flow sensor, throttle position sensor, the cooling-water temperature sensor of gas internal-combustion engine cooling jacket, detonation sensor, the crank position ignition timing rotating speed integrated transducer of gas internal-combustion engine oil spout on the gear shaft given in installation, lambda sensor is electrically connected, its output terminal respectively with the fuel injection electromagnetic valve, the spark coil of spark plug is electrically connected.The microcomputer of this microcomputer control gas internal-combustion engine is only according to the aperture of the SC sigmal control fuel injection electromagnetic valve of air flow sensor, throttle position sensor, cooling-water temperature sensor, detonation sensor, crank position ignition timing rotating speed integrated transducer and lambda sensor, and the suction tude of gas internal-combustion engine is not controlled, the charging efficiency of gas internal-combustion engine can not guarantee to be in higher level, and the output power of gas internal-combustion engine can reduce.
In view of above deficiency, those skilled in the art have proposed technological scheme as shown in Figure 1, the vacuum actor, vacuum solenoid, vacuum chamber, one-way valve, the suction tude that comprise electronic engine management system ECU, crankshaft rotational speed sensor, be connected in series successively by connecting tube; This suction tude is provided with the butterfly valve assembly, and the pull bar of vacuum actor is connected with the valve of butterfly valve assembly, and pull bar can spur valve to control the switch of this valve; This vacuum solenoid is a two-position three-way valve, the air bag of vacuum actor can be communicated with vacuum chamber or the air bag of vacuum actor is communicated with atmosphere; Electronic engine management system ECU is communicated with vacuum chamber or is communicated with atmosphere according to the SC sigmal control vacuum solenoid of the crankshaft rotational speed sensor air bag with vacuum actor: when electronic engine management system ECU gives the vacuum solenoid power on signal, the vacuum solenoid energising is with the air bag and the vacuum chamber of vacuum actor, gas in the final controlling element in the air bag flows to vacuum chamber by solenoid valve and pipeline, inhale lower link, the valve closing of butterfly valve assembly; When electronic engine management system ECU gave the vacuum solenoid power-off signal, the vacuum solenoid outage was communicated with the air bag of vacuum actor with atmosphere, and air bag is extensive previous condition under the effect of elastic force, and pull bar resets, the valve opening of butterfly valve assembly.
Engine start moment vacuum intracavity gas flows to suction tude by one-way valve, and vacuum actor is closed the dish valve.Vacuum chamber pressure approaches the air pressure of suction tude during idling.When suction press rises owing to adopt one-way valve to connect, by vacuum actor, vacuum solenoid, vacuum chamber, and the system pressure formed of connecting pipeline constant.When engine speed reached certain value, for example during 4500rpm, electronic engine management system ECU cut off the power supply to vacuum solenoid, the air bag of vacuum actor is communicated with atmosphere and opens butterfly valve.The system pressure that be made up of vacuum chamber, one-way valve, vacuum solenoid sealed end this moment is constant.
Butterfly valve assembly with aforesaid way control suction tude, have following shortcoming: when fully loaded motor when high rotational speed changes continuously, for example at 4000rpm to changing continuously between the 5000rpm, the dish valve assembly needs repeatedly opening and closing, and this moment, vacuum chamber constantly was drawn into air in vacuum actor, and the air pressure in the vacuum chamber progressively rises; When the vacuum chamber internal air pressure rose to certain stage, vacuum actor just can't be worked again.The vacuum that stores when idling of vacuum chamber on the suction tude can only be inhaled the vacuum actor 2 to 3 times of leaving behind fully after tested, and later final controlling element just can not be opened fully.Therefore, if engine speed 4000rpm between the 5000rpm up and down repeatedly the fluctuation after, the dish valve assembly just can not be opened.
