Abstract

The invention discloses an SCR urea supply system device and particularly relates to a connecting method for an SCR urea supply system assembly for a vehicle. The SCR urea supply system device comprises a urea pump, a urea sensor connector and a urea tank assembly. The urea pump is communicated with the urea tank assembly through the urea sensor connector. By means of the structure, during operation of an SCR system, the urea pump and the urea tank are integrated, urea inlet lines are saved, and urea is sucked in a filling mode. A water cooling liquid of a motor heats the urea pump and then heats urea in the urea tank through the urea sensor connector, so that heating lines are saved. According to the method, a plurality of accessory costs can be saved, and the whole SCR system prices is reduced; and the size is small, mounting is compact, and convenience is provided for adding of an SCR exhaust purification system to the vehicle.

Description

The connecting means of automobile-used SCR urea supply system assembly
Technical field
The present invention relates to motor-vehicle tail-gas equipment for after-treatment technical field, relating in particular to a kind of SCR urea supply system and urea storage device thereof, urea pump connecting means.
Background technique
Along with the progress of emission control technique and constantly adding sternly of standard, from implementing " state's I standard " to " state's IV standard ", Motor Vehicle bicycle discharging accumulative total has reduced the pollutant more than 97%, has advanced the process of automobile pollution control work greatly.Existing known, reduce by the SCR technology that nitrogen oxide is a kind of general technology path in the diesel engine vent gas, existing automobile-used SCR urea supply system is European countries' design mostly and produces, all be to adopt urea pump mostly, urea box is installed in the method for car body respectively, is connected to each other by the urea line, to installing and using and caused certain inconvenience, increased the cost of urea line, and installing space has been had certain requirement.
Summary of the invention
The present invention is in order to overcome the more efficient of above technical deficiency design, volume is littler, function is more complete, the automobile-used SCR urea supply system assembly connecting means that cost is lower, save a large amount of urea lines and heating pipe line, urea pump and urea box are integrated, so easy for installation, once mounting just can be finished the placement of a whole set of SCR urea supply system.Functional level of integration height can while heating urea pump and urea box inside during heating.
Useful explanation
The beneficial effect that adopts the present invention to produce is as follows:
Installation cost reduces, and installing space reduces, and for the installation of SCR urea supply system provides convenience, prior art is optimized, and particularly heating system has improved the efficiency of heating surface to urea greatly.Save urea feed liquor line, also improved the extraction efficiency of urea.
