How does the urea box wash | and urea filling machine?
The shape of the observation window of urea liquid level also has its own characteristics for example there are round Windows there are tubular columns and white boxes are used for easy observation and more direct lines are used. There may be some confusion why not fill it up?
The urea solution will freeze in the cold leaving the tank with an expansion volume.
The first thing we need to understand is that the urea solution will freeze in cold conditions like water and once it freezes it will have a certain expansion rate. At the current widely used in 32.5% of the urea solution - 11 ℃ when will start to freeze and a crystal precipitation therefore urea would provide 10% of the volume expansion in the box. The addition of urea to the freezing may damage the box and the sensor.
What is the cause of the sudden increase in fuel consumption of the four vehicles in China?
Recently in the truck BBS there was a very hot news. A brother bought a five truck from a country and then ran 30000 kilometers feeling inadequate and consuming more and more oil. Go to the repair shop to check the result is the front end of the SCR system catalytic converter good and urea refueling machine has been blocked by a large white solid block.
We know through professional processing plant maintenance technician analysis that in addition to using urea solution quality may not be qualified there is a very important also is a large part of the cause of the truck driver is not familiar with that is not on the SCR urea system for regular maintenance.
Under normal circumstances if the vehicle does not burn urea the SCR system will report the failure of exceeding 5g/kw. H and over 7g/kw. H and then the car will be limited (usually the opportunity is limited to 60% of the power output). State IV vehicles consume 100L of diesel fuel equivalent to 3l-5l of urea and if it is beyond this range no matter more or less is abnormal work phenomenon it needs to be repaired. Main urea consumption is relatively short or the long-distance transportation vehicle city road vehicles more and more than in the winter and summer the reason is urea injection conditions need exhaust temperature of 200 degrees of above.
