The detector includes a detection part and a fixed part installed on it, and the detection part is divided into oxygen sensor and arranged on the exhaust pipe of the motorcycle through the fixed screwdriver of the fixed part. Said oxygen sensor is zirconia pipe type oxygen sensor. The utility model is arranged with oxygen sensor on motorcycles, matching with electrically fuel spraying system, it is energy-saving and environment-protecting, and it is installed in the fixed screwdriver method, secure and reliable, with simple structure and convenient making, and has a small size and low cost.
Description
Technical field
The utility model relates to the sniffer of motorcycle engine combustion position, whether fully it is a kind of detection motorcycle engine mixed gas burning detective device, by its sensing signal, deliver to fuel feeding closed-circuit system on the car, adjust air and fuel ratio in good time, reach optimal combustion state, realize saving the purpose of fuel oil and exhaust environmental protection.
Background technique
At present, the air of mixed gas and fuel ratio in the motorcycle engine cylinder, preestablish realization by the mechanical-type Carburetor, this hybrid mode exists the air fuel ratio inaccuracy, exhausting air after the burning can't detect, problem such as can not adjust in good time, make engine fuel can not reach best fully combustion regime, have fuel oil waste and air-polluting problem.
The model utility content
In order to overcome the problem that exists in the empty combustion mixing of existing motorcycle engine burning, the invention provides a kind of sniffer of motorcycle engine combustion position, in the motor exhaust pipeline, lambda sensor is installed, at any time monitor the oxygen content in the engine exhaust, oxygen content height in the waste gas, then mixed gas is rare, oxygen content in the waste gas is low, then mixed gas is dense, and lambda sensor changes the oxygen content in the waste gas into electrical signal, offers the fuel feeding closed-circuit system on the motorcycle, handle by computer in the system, adjust the fuel feeding amplitude, thereby realize the optimal proportion that the engine air fuel oil mixes, reach energy-conservation, the purpose of environmental protection.
The technical solution of the utility model is:
A kind of sniffer of motorcycle engine combustion position comprises probe portion and the standing part that is mounted thereon, and probe portion is a lambda sensor, and the fixedly Luo button that probe portion is offered by standing part is installed on the motorcycle exhaust pipe.
Described lambda sensor is a zirconium oxide cast lambda sensor.
Described zirconium oxide cast lambda sensor, comprise tubular zirconium-oxide, sheath, hexagonal pedestal, tail cover, sheath, hexagonal pedestal, tail cover are connected into housing in mechanical crimping mode successively, tubular zirconium-oxide places the sheath inboard, the fixedly Luo button that hexagonal pedestal one side is offered is installed in lambda sensor on the motorcycle exhaust pipe, and negative electrode platinum layer electrode, anode platinum layer electrode on the tubular zirconium-oxide are drawn by conducting plate, lead respectively.
Establish resistance heater in the described tubular zirconium-oxide.
Described tubular zirconium-oxide is the pipe member of end sealing; the inside and outside platinum layer that is coated with of tubular zirconium-oxide; platinum layer is provided with extraction electrode and makes gas sensitive element; skin is a negative electrode platinum layer electrode; internal layer is an anode platinum layer electrode; gas sensitive element by the sheath protection places the motorcycle engine exhaust duct, and the skin of zirconium oxide gas sensitive element contacts with discharging waste gas, and the internal layer of zirconium oxide gas sensitive element contacts with atmosphere.
The utility model adopts motorcycle Luo to detain fixed zirconium oxide cast lambda sensor, utilizes zirconium oxide (high temperature and platinum catalysis) under certain condition, when the oxygen concentration of both sides, zirconium inside and outside has difference, produce potential difference, and concentration difference is big more, the characteristic that potential difference is big more.Zirconium oxide sintering is made the pipe member of a sealing; and inner tube layer and skin coated platinum; the platinum skin is coated with netted pottery protection; platinum layer is provided with extraction electrode; make gas sensitive element, gas sensitive element is protected through metallic case, place the motorcycle engine exhaust duct; the skin of zirconium oxide gas sensitive element is contacted with discharging waste gas, and internal layer contacts with atmosphere.When the waste gas of engine emission passes through the zirconium oxide gas sensitive element, because the oxygen content in the atmosphere is than the oxygen content height in the waste gas, the a tubulose gas sensitive element side attached more negative ion of a side draught that communicates than with waste gas that communicates with atmosphere, thereby the ion concentration of both sides is poor, just can produce electromotive force, the size of electromotive force changes with the oxygen concentration of gas sensitive element waste gas one side, when oxygen concentration hangs down, voltage height between the electrode, on the contrary voltage is then low.Voltage signal is sent to the computer processor of motorcycle oil supply system, computer processor is regarded high voltage signal as rich mixture, low voltage signal is regarded as weak mixture, according to the voltage signal of sensor, computer control engine fuel system is regulated and is given oil mass, make air-fuel mixture enrichment or dilution, all the time keep optimum mixture ratio, be in good combustion regime, reach energy-conservation and purpose environmental protection to guarantee motor.In order to satisfy the characteristics that zirconium oxide is at high temperature worked, in lambda sensor, install resistance heater additional, work immediately when motorcycle initial start, the engine cold state to guarantee lambda sensor.
The beneficial effects of the utility model are:
The utility model is installed lambda sensor on motorcycle, cooperate the fuel oil electric injection system, can reach the effect of energy-saving and environmental protection, installs with Luo button means of fixation, and is solid and reliable, and simple in structure, easy to make, and volume is little, cost is low.
