The heater relay is a normally-open contact relay. The temperature switch is a normally-closed contact relay. An output terminal A of four terminals of the controller is connected with the heater relay through the temperature switch, a power supply terminal B is connected with a power supply through the ignition switch, a signal terminal C is connected with a trigger coil of a magneto and the magneto, and a grounding terminal E is connected with a negative pole of the storage battery. The device is novel in design and reasonable in structure, and can use the temperature sensor to sense the low-speed running of an engine and send a signal to turn on the primary heating circuit to realize heating of the exhaust muffler, so that the temperature of exhaust is raised to an initiation temperature of the catalytic converter to convert the exhaust quickly.
Description
Technical field
The invention belongs to the exhaust muffler for motorcycle technology, mainly propose a kind of heating type exhausting silencer of motorcycle.
Background technique
At present, motorcycle is in order to satisfy three stage emission compliance standards (GB14622-2007) of the new promulgation of State Bureau of Environmental Protection, must install catalytic converter additional in exhaust muffler for motorcycle, by catalysis, the harmful gas in the tail gas changes innocuous gas into the most at last; Because catalytic converter needs certain temperature when ignition is worked, thereby catalytic converter can't be worked when starting a cold engine, consequently: the tail gas before the ignition can not be transformed, and this part tail gas has very big discharge amount to atmospheric pollution, so must take certain measure to be controlled.
Summary of the invention
The objective of the invention is to propose to make the catalytic converter ignition work at short notice in the exhaust system for motorcycle and motorcycle, effectively reduce discharge amount at a kind of motorcycle heating type exhausting device.
Purpose of the present invention can adopt following technological scheme to realize: a kind of motorcycle heating type exhausting device, it comprises outlet pipe and silencing apparatus and catalytic converter, outlet pipe and silencing apparatus combine as a whole and constitute the exhaust passage, catalytic converter is installed in the silencing apparatus front portion, and heating resistor and temperature transducer are set between outlet pipe and catalytic converter.
Heating resistor is by protective tube and ignition switch and add thermorelay and thermal switch and storage battery connect and compose the heating major loop, and adding thermorelay is the normally opened contact relay, and thermal switch is the normally-closed contact relay; In the control loop, controller has four terminals, wherein output terminals A by thermal switch with add thermorelay and be connected, power end B is connected with power supply by ignition switch, signal end C is connected with magnetogenerator trigger winding, magnetogenerator, the negative pole end ground connection of grounding end E and storage battery.
Modern design of the present invention, rational in infrastructure, after being installed on the car load, can pass through the sensor senses time of engine low speed, thereby transmitting signal makes the conducting of heating major loop realize the exhaust silencer heating, make delivery temperature rise to Temperature of Catalytic Converter at short notice, fast waste gas is transformed; In case behind the catalytic converter ignition, a large amount of heat releases of self meeting, promptly sustainable assurance is to the changing effect of tail gas; After catalyst entry end delivery temperature reached 240 ℃, temperature transducer transmits signal disconnected thermal switch, thereby makes heating resistor stop heating.

Embodiment
The embodiment who provides in conjunction with the accompanying drawings further specifies the present invention:
As shown in Figure 1, the present invention includes outlet pipe 5 and silencing apparatus 1 and catalytic converter 2, outlet pipe 5 and silencing apparatus 1 combine as a whole and constitute the exhaust passage, and between silencing apparatus 1 and outlet pipe 5, catalytic converter 2 is set, heating resistor 4 and temperature transducer 3 are set between outlet pipe 5 and catalytic converter 2; Working procedure of the present invention is: after the engine start, tail gas flows into catalytic converter 2 by outlet pipe 5 and after heating resistor 4 heating, enters atmosphere by silencing apparatus 2 at last; When motor just starts, the exhaust exhaust temperature at temperature transducer 3 places is lower, can not reach the initiation temperature of catalytic converter, but after heating resistor 4 heating, the very fast delivery temperature of catalytic converter 2 inlets that can make rises to initiation temperature, behind the ignition, catalytic converter 2 can be converted into innocuous gas CO with the harmful gas CO/HC/NOX in the tail gas rapidly

2, finally realized emission compliance; Because the resistance wire heating need expend storage battery energy,,, 3 pairs of resistance wire heating of a temperature transducer control so being set so when the delivery temperature of catalytic converter inlet reaches a threshold value, it must be cut off to save electric weight.
As shown in Figure 2, heating resistor 4 is by protective tube 7 and ignition switch 14 and add thermorelay 12 and thermal switch 13 connects and composes the heating major loop with storage battery 6, adds thermorelay 12 and is the normally opened contact relay, and thermal switch 13 is the normally-closed contact relay; In the control loop, as shown in Figure 3, controller has four terminals, wherein output terminals A by thermal switch with add thermorelay and be connected, power end B is connected with power supply by ignition switch, and signal end C is connected with magnetogenerator trigger winding, magnetogenerator, and the negative pole end of grounding end E storage battery connects; The contact of described controller is open in usual, when starting motorcycle, motor is in idle state, controller is by magnetogenerator trigger winding perception slow-speed of revolution signal, and connection adds thermorelay, makes heating resistor work in the silencing apparatus, heating rapidly, make exhaust temperature reach Temperature of Catalytic Converter in time about 20S greatly, thereby catalytic converter is started working, realize that engine emission is up to standard; Behind the engine running 2 minutes, the delivery temperature of catalytic converter front end has reached more than 240 °, and temperature transducer transmission this moment signal disconnects thermal switch, adds thermorelay and quits work, and returns to the motorcycle normal state.
The working procedure of controller is as follows: shown in Fig. 2,3, during engine operation, trigger signal inputs to special chip IC through the C end, when engine speed arrives designing requirement 750r/min~1000r/min, chip IC one end output voltage, promptly resistance R 2 two ends have voltage to cause thyristor Q1 conducting, then resistance R 4 two ends have voltage to cause thyristor Q2 conducting, thereby relay J 2 conductings, the single-phase connection of normally opened contact (A end and B end: the B end is timing), the control motorcycle adds thermorelay work.
