Description
Technical field
The present invention relates to be used for throttle body and gas fuel mixer on the motor car engine.
Background technique
Gas fuel mixer on the automobile is that gaseous fuel and air are fully mixed formation inflammable mixture supply engine.Mixer should be able to air fuel is fully, uniform mix, and according to the variation of engine speed and load, adjust the concentration and the supply of mixed gas, to adapt to the needs of motor normal operation under different operating conditionss such as starting, idling, acceleration, guarantee power character, Economy and the emission performance of motor.
Throttle body on the automobile is the mixed gas supply engine by throttle and control panel.Throttle body should be installed electric control element to satisfy the performance need of motor under different operating conditionss, guarantees the power character and the Economy of motor.
Present employed mixer and throttle body are two component that separate, and be bulky, and it is many to take up room, and needs 2～3 bend pipes and transfer tube just can be installed on the motor, and dismounting is also very inconvenient.
Nowadays car load is more and more higher to the requirement of idling, from power character, Economy still be the driving this link of idling all stand in the breach; And along with the requirement difference of different types of vehicle to idling, as the air-conditioning power of luxurious air-conditioned passenger train up to more than 20 kilowatts; Motor can be used to travel and can be used for generating (generally using two motors division of labor to finish); Also have various engineerings can utilize motor to finish with the lifting of car, upset etc.In order to adapt to the requirement of various different vehicle, the traffic demand during engine idle is just different, considers all to use the idling mechanism of big flow from aspect of performance without exception, so just needs a kind of idle speed controller that can conveniently change the idling peak rate of flow.
Summary of the invention
In order to make part more succinct, light, volume is smaller and more exquisite, dismounting is easier, and the power of assurance motor, economy and discharging, make idle speed control more convenient, more comprehensively, the invention provides that a kind of gas collection fluid fuel sprays (can select to install two kinds of different types of nozzles by changing the nozzle installed module), mixer, idling bypath air control (can conveniently change the idling peak rate of flow), throttle body function split type automatically controlled gaseous fuel sprays throttle body.
For this reason, the technical solution of the utility model is as follows: split type automatically controlled gaseous fuel sprays throttle body, comprise a body, the cylindrical body that the one band cavity of giving prominence to is arranged on the body, cylindrical cavity is a main airway, be provided with the choke valve sheet in the hypomere of main airway, the middle part of choke valve sheet is connected with the rotating shaft of radial arrangement; A side is provided with nozzle installation cavity, air collecting chamber from outside to inside on main body, nozzle installation cavity, air collecting chamber coaxial arrangement; The side of nozzle installation cavity, air collecting chamber is provided with pressure stabilizing cavity, and pressure stabilizing cavity communicates with the nozzle installation cavity; End at pressure stabilizing cavity is the gaseous fuel inlet hole; Air collecting chamber communicates with the circular groove of cylindrical body outer wall, and cylindrical inner chamber epimere partly is provided with along a plurality of fumaroles uniform on the circumference and communicates with circular groove; On the main airway between fumarole and the choke valve sheet, be provided with the idling by-pass hole.
Technique scheme is further improved, on pressure stabilizing cavity, can be provided with temperature transducer mounting hole and pressure transducer mounting hole.
In technique scheme, the nozzle installation cavity is an independent module, has two kinds of modules can be installed on the throttle body nozzle of every kind of each corresponding a kind of pattern of module.
In described technological scheme, also be provided with the bypath air hole on the body, the inlet hole by this Kong Keyu idling bypass valve is communicated with, thereby crosses the suction tude that the air outlet hole of blowing air valve enters motor by the step motor control air flow stream again.This idling bypass valve is an independent structure, and the peak rate of flow of its circulation can be changed according to the demand of vehicle, can conveniently satisfy the idling demand under the different situations.
Below, use rock gas to introduce its function, purposes with the utility model as example.During use, need to give the supporting installation nozzle of this throttle body, throttle position sensor, the rotating shaft and the gas pedal of idle speed step motor, choke valve sheet are in transmission connection.Air enters from main airway, rock gas enters pressure stabilizing cavity through the decompression back from the rock gas inlet hole, enter nozzle through behind the pressure stabilizing cavity, flow through the flow and the opportunity of nozzle installation cavity by nozzle control rock gas, the rock gas that flows out from nozzle all enters air collecting chamber at last, enters main airway and air mixing then; Air is with after rock gas fully mixes, and just regulated the mixed gas air inflow that enters motor by the open and close of gas pedal control closure valve block.When the closure valve block was closed, motor was in idling mode, and mixed gas can enter motor from the bypath air hole.
Temperature transducer mounting hole and pressure transducer mounting hole are set on pressure stabilizing cavity, and mounting temperature sensor, pressure transducer are the states for the ease of the monitoring gaseous fuel, make air inlet mixing, air fuel ratio more accurate.
The idling by-pass hole is set on body, and the idling bypass valve is independent structure, on the idling bypass valve, idle speed step motor is installed, is regulated discharge value with the flow area of control bypath air passage by idle speed step motor and enter main airway again, thus the throttling action of playing.According to conveniently replaced idling bypass valve of the demand of different vehicle and idle speed step motor, to avoid directly changing whole body.
The summary the beneficial effects of the utility model are as follows: the utility model by one-piece element integrated gaseous fuel injection (can select to install two kinds of different types of nozzles), mixer, throttle body, idling bypath air control (can conveniently change the idling peak rate of flow), installation multiple sensors function by changing the nozzle installed module, do not need transfer tube just can install, make part more succinct, light, volume is smaller and more exquisite, dismounting is easier, satisfies power, economy and the emission performance of motor simultaneously.
