Abstract
The utility model relates to the anti-burning system of gas-fueled vehicles three-way catalytic apparatus, it is mainly made up of the control unit that is arranged at the various sensors of gas holder, gas ejector, motor, electromagnetic shut-off valve, air-strainer, throttle valve and be connected with these various sensor signals, between described gas holder, gas ejector, motor, electromagnetic shut-off valve, air-strainer and throttle valve, connects by tracheae.The utility model is by arranging various sensors, to ensure that unburned gas enters in three-way catalytic apparatus, contact with catalyzer and burn and cause causing that high temperature causes the inefficacy of catalysis device to overcome unburned gas, ensured vehicle driving safety in the time of the few pressure drop of gas pressure residual.
Description
Technical field
The utility model relates to the anti-burning system of a kind of gas-fueled vehicles three-way catalytic apparatus.
Background technique
What the automobile with compressed natural gas that compressed natural gas is fuel at present adopted is three-way catalytic apparatus, these gas-fueled vehicles are in the time advancing, when gas residual in CNG tank is very few, engine fuel is not enough to be occurred flame-outly, easily causes security incident to occur.In addition, under such state, if the driving of vehicle continues (as in running at high speed), when unburned gas is discharged from three-way catalytic apparatus, because of automobile low-speed travel catalyzer temperature raise, so unburned gas contacts and takes fire with the catalyzer in three-way catalytic apparatus, produce heating extremely, thereby cause the inefficacy of catalysis device.
Summary of the invention
The utility model is in order to solve existing above-mentioned technical problem, thereby proposes the anti-burning system of a kind of gas-fueled vehicles three-way catalytic apparatus, to ensure vehicle driving safety when the few pressure drop of gas pressure residual.
The utility model is realized by following scheme:
The anti-burning system of above-mentioned gas-fueled vehicles three-way catalytic apparatus, mainly formed by the control unit that is arranged at the various sensors of gas holder, gas ejector, motor, electromagnetic shut-off valve, air-strainer, throttle valve and be connected with these various sensor signals, between described gas holder, gas ejector, motor, electromagnetic shut-off valve, air-strainer and throttle valve, connect by tracheae.
The anti-burning system of described gas-fueled vehicles three-way catalytic apparatus, wherein: the outlet end of described natural gas storage tank is provided with pressure regulator, tank body gas pressure sensor and tank body gas temperature sensor; The entry end of described gas ejector is provided with the gentle temperature transducer of gas pressure sensor; The suction port of described motor is provided with air-strainer, throttle valve and throttle valve surge groove; Burning pressure sensor, cooling-water temperature sensor, engine rotation speed sensor and vehicle speed sensor are set in firing chamber; Outlet is provided with air-fuel ratio sensor; Described air-strainer inlet end is provided with temperature transducer; Described throttle valve is provided with the throttling sensor of interlock; Described surge groove air intake branch is provided with pressure transducer.
Beneficial effect:
By locating to arrange various sensors at gas holder, gas ejector, motor, electromagnetic shut-off valve, air-strainer and throttle valve etc., control gas emitted dose and discharge time thereby reach, to ensure that unburned gas enters in three-way catalytic apparatus, contact with catalyzer and burn and cause causing that high temperature causes the inefficacy of catalysis device to overcome unburned gas, ensured vehicle driving safety in the time of the few pressure drop of gas pressure residual.
