Abstract
The present invention relates to a matching method for a catalytic cleaner of a motorcycle. The matching method has the technical scheme that according to reshaped motorcycle types, the contrast comparison of original engine emission and emission control objects, and matching principles of reasonable share of inner engine purification and outer engine purification, and antecedent inner engine purification, inner engine emissions control measures are selected with pertinency to decrease the original engine emission; through real time operating condition and temperature field measurement of an exhaust pipe, the layout of a catalytic cleaner is guided; through the real time oxygen concentration measurement of exhaust, the catalytic cleaner is determined whether secondary air is needed or not. The matching method has the advantages that the inner engine purification and the outer engine purification are reasonably shared, and has universal guiding significance for the match of catalytic purifiers and motorcycles; the matching method has good effect and high operability.
Description
Technical field
The present invention relates to catalytic cleaner matching method for motorcycle.
Background technique
China is as the first producing country of world's motorcycle and possess state, and the exhaust emissions problem of being brought by motorcycle is serious day by day, has caused government, enterprise and user's attention.The catalytic cleaner technology is to reduce the advanced technology of motorcycle exhaust discharging, and wherein the coupling of catalytic cleaner and motorcycle is a catalyst converter key in application link.
At present, disclosed patent and non-patent literature are only to having carried out reporting (catalytic converter and Engine Matching research by numerical simulation calculation from how former mechanomotive force, economic influence angle are mated, Wuhan Auto Industry University's journal, 2000 the 22nd volume first phases), but how making with the catalytic purification by matched well is the matching process that catalytic cleaner that purpose is installed is given full play to catharsis, yet there are no report.
Summary of the invention
The object of the present invention is to provide a kind of method that instructs catalytic cleaner and motorcycle coupling.Utilize outlet pipe real time temperature field measurement to instruct the method for catalytic cleaner and motorcycle coupling.
Technology of the present invention is: at being transformed the motorcycle vehicle, by comparing of its former machine discharging and emission control target, rationally share in line with emission controls by improving combustion and external purification, the matching principle that emission controls by improving combustion is gone ahead of the rest, control techniques reduces former machine discharging in the selector targetedly, instructs the layout of catalytic cleaner by the measurement in outlet pipe real-time working condition temperature field.
Concrete steps are that some thermocouples are arranged at the position that catalytic cleaner might be installed on former machine outlet pipe, in carrying out the behavior method discharging process of the test, the temperature curve of different points for measuring temperature in the real time record process of the test, in conjunction with the initiation temperature characteristic of catalytic cleaner, thereby can determine the layout area of catalytic converter.
The advantage of this matching process is to follow emission controls by improving combustion and external purification is rationally shared, the matching principle that emission controls by improving combustion is gone ahead of the rest, from the purifying effect of the potentiality of giving full play to motorcycle itself and catalytic cleaner as starting point, from influencing temperature factor that catalytic cleaner plays a role as point of penetration, coupling for catalytic cleaner and motorcycle has general directive significance, effective, workable.
Description of drawings
Fig. 1: AXIS90 outlet pipe thermocouple is arranged schematic representation;
Fig. 2: the temperature curve of corresponding each measuring point of AXIS90 outlet pipe;
Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments:
Example 1: the application of outlet pipe real time temperature field measurement on AXIS90 two-stroke motorcycle catalytic converter coupling.
Fig. 1 arranges schematic representation at AXIS90 outlet pipe thermocouple, we are along the flow direction of waste gas in outlet pipe, in the area arrangements that may arrange catalytic cleaner thermocouple, wherein point for measuring temperature 1 is represented delivery temperature, point for measuring temperature 2 expressions flow into the temperature before the outlet pipe cavity, and point for measuring temperature 3,4 is represented the temperature of first and second expansion chamber respectively.
Fig. 2 for the AXIS90 two-stroke motorcycle in carrying out ECE40 behavior method discharging process of the test, the temperature curve of corresponding each point for measuring temperature.The abscissa of Fig. 2 is the time of behavior method discharging test, y coordinate is a temperature value, temperature curve shows, 1,2,3 corresponding temperature range can reach the requirement of general catalytic cleaner initiation temperature, that is to say, have only catalytic cleaner is arranged in the scope that 1,2,3 measuring points are surrounded, catalytic cleaner just might have been given play to catharsis.
Claims (1)
1. a catalytic cleaner matching method for motorcycle is characterized in that utilizing outlet pipe real time temperature field measurement to instruct the method for catalytic cleaner and motorcycle coupling; The position of catalytic cleaner might be installed on former machine outlet pipe arrange thermocouple, in carrying out the behavior method discharging process of the test, the temperature curve of different points for measuring temperature in the real time record process of the test in conjunction with the initiation temperature characteristic of catalytic cleaner, is determined the layout area of catalytic cleaner.
