Description

  The present invention relates to a reducing agent replenishing container that houses and carries a reducing agent (urea water) used in an exhaust gas purification device of a diesel engine.

As an exhaust gas purification device for diesel engines such as trucks and buses, an SCR (Selectvee) that uses urea as a reducing agent to purify nitrogen oxides (NOx) in the exhaust gas.
The use of a catalytic reduction catalyst has been put into practical use.
An exhaust gas purification apparatus using an SCR catalyst is an SCR having the property of selectively reacting nitrogen oxide (NOx) in exhaust gas with a reducing agent in the middle of an exhaust pipe through which exhaust gas flows, even in the presence of oxygen. And NOx in the exhaust gas is selectively adsorbed on the SCR catalyst for purification.
Injecting urea water into the exhaust passage upstream of the SCR catalyst, hydrolyzing urea in the urea water to generate ammonia (NH ₃ ) as a reducing agent, supplying ammonia to the SCR catalyst, and the SCR catalyst NOx adsorbed on the NOx is reduced, decomposed into nitrogen and water and discharged, thereby reducing the NOx discharge concentration.

  In a vehicle using such an exhaust gas purification apparatus using an SCR catalyst, a urea water tank for storing urea water is provided in order to inject quantity water into the exhaust passage on the upstream side of the SCR catalyst. When the urea water in the water tank runs out, it is necessary to purchase and supply it at a stand having a dedicated facility, a dealer, or the like.

  However, urea water is also limited in stores and cannot be easily obtained like fuel. Therefore, the driver often carries several liters of urea water in a general-purpose container in order to reduce the risk of running out of urea water as much as possible. When the acquisition timing is lost, the urea water stored in the replenishment container in advance may be replenished into the urea water tank to ensure the function of the exhaust gas purification device.

The following known examples are known as general portable liquid containers.
