Description

Mounting structure of on-vehicle urea jar

Technical Field

The utility model belongs to the technical field of construction machinery's technique and specifically relates to a mounting structure of on-vehicle urea jar is related to.

Background

The slag car, also called as a soil pulling car and a slag transport car, is not specific to which car, but refers to a truck for transporting building materials such as sand and stone. Because of large carrying capacity requirements, most of the muck trucks use a diesel engine as power, and the current diesel engine needs to meet the discharge standard of national IV. The SCR solution has significant advantages in the tail gas emission treatment system of national iv diesel vehicles, whereas automotive urea is a necessary additive for the SCR solution. Since the vehicle-mounted urea is alkaline, the vehicle-mounted urea tank is mostly made of plastic.
