Description

[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple air venting method for cooling water in a water-cooled engine system, which uses an apparatus for simultaneously cleaning the inside of the water-cooled engine system and regenerating the coolant (also referred to as cooling water). It is about.
[0002]
2. Description of the Related Art In recent years, internal cleaning of a water-cooled engine system and coolant regeneration processing have been performed, and these coolants are returned to the engine system again after regeneration processing, so there is no need to dispose of them. The natural environment is being protected. For such an internal cleaning of a water-cooled engine system and a coolant regeneration process, there have been known several documents such as those for cleaning the radiator and those for cleaning the engine and the radiator together. For example, a cooling means including a cooling water treatment tank, a diaphragm pump, a filter, and a switching area. After introducing an additive into the cooling water treatment tank, the inside of the water-cooled engine system is washed using the washing means. And the cooling water cleaning process simultaneously, the cleaning means connects two pipes of the cooling water processing tank to the switching area respectively, while the pipe extending from the switching part of the switching area is a diaphragm pump. , Connect to the filter in turn, and then connect the pipes that exit from the filter to the other switching sections in the switching area. There is disclosed a method for simultaneously performing the internal cleaning of the water-cooled engine system and the cleaning treatment of the cooling water, wherein the cleaning means has a T-shaped connection portion and a radiator connection portion. (For example, refer to Patent Document 1).
[0003]
Also, it has an engine side connection part, a radiator side connection part and a connection part for sucking coolant in the radiator, and a pair of circulation cleaning / regeneration circuits connected to these are respectively connected to the discharge port and suction port of each pump of the diaphragm pump. In an apparatus that simultaneously performs internal cleaning of a water-cooled engine system and coolant regeneration processing that are independently connected, the circulation cleaning / regeneration circuit is connected to a filter through a conduit to the suction port of the pump. The pipe connected to the discharge port of the pump is connected to the engine connection portion, and the pipe is connected to a pipe having a pressure gauge, a safety valve, and an open / close valve leading to the tank, and The suction connection part is connected to the switching valve via a pipe line, and one pipe line coming out of the switching valve is connected to the filter, and the other pipe line is connected to the tank, The radiator-side connecting portion, simultaneously apparatus and a reproduction processing inside cleaning and coolant water-cooled engine system, characterized in that it consists are connected is disclosed to the tank (see Patent Document 2). All of these devices perform internal cleaning of the water-cooled engine system and coolant regeneration at the same time, and it is possible to protect the natural environment without causing environmental pollution in that there is no need to drain coolant around. It can be done.

In recent years, there have been many opportunities to perform operations such as replacement of cooling water for automobile radiators, accidents and repairs, and at that time, it has been necessary to fill or replenish the extracted cooling water. It is necessary to replenish the cooling water and remove the air in the filled cooling water, and the current situation is that it takes 3 hours to several hours depending on the type of vehicle. Therefore, the present invention has been studied in order to solve these problems, and as a result, the interior of the water-cooled engine system is washed in a vehicle type, in particular, a vehicle type having a rear heater core (for example, Nissan Largo, Serena, 5 number model). It was found that air can be easily ventilated by connecting a device that simultaneously performs a coolant regeneration process and introducing cooling water. Therefore, the problem to be solved by the present invention is that it is possible to easily remove air from a vehicle having the rear heater core by using an apparatus that simultaneously performs internal cleaning of the water-cooled engine system and coolant regeneration processing. The object is to provide a simple air venting method for cooling water of a water-cooled engine system.
