Embodiment Construction

[0021] The method of the present invention is further described below in conjunction with the accompanying drawings, which are used to explain the method of the present invention together with the embodiments of the method of the present invention, and do not constitute a limitation to the method of the present invention.

[0022] Such as figure 1 As shown, the cooling system applicable to the degassing method of the diesel engine cooling system of the present invention includes a degassing joint 1, a water inlet pipe 3, a water jacket 5 on the cylinder head, a water jacket 11 under the cylinder head, a water jacket 13 for the cylinder block, and a water collection for the cylinder block Manager 8. The water inlet main pipe 3 is at the highest position of the cooling system. The degassing joint 1 is installed at the highest position above the water inlet main pipe 3 . The degassing connection 1 has an orifice 2.

[0023] Such as figure 1 As shown, when the diesel engine is...

Abstract

The invention relates to a method for degassing the cooling system of a diesel engine. The cooling system includes a degassing joint, a water inlet main pipe, a water jacket on the cylinder head, a water jacket under the cylinder head, a water jacket on the cylinder block and a water collection main pipe on the cylinder block; the degassing joint is installed on At the highest position above the water inlet pipe, the coolant of the diesel engine enters the upper water jacket of the cylinder head, the lower water jacket of the cylinder head, the water jacket of the cylinder block and the water collection pipe of the cylinder block from the water inlet pipe in sequence; The water jacket enters the lower water jacket of the cylinder head and the upper water jacket of the cylinder head in turn, collects the air bubbles generated by the coolant in the lower water jacket of the cylinder head and the upper water jacket of the cylinder head, enters the water inlet main pipe, and is discharged through the degassing joint. The coolant of the diesel engine cooling system and the air bubbles generated by the coolant during the operation of the diesel engine move in the opposite direction to ensure that the air bubbles generated by the coolant are discharged at any time during the operation of the diesel engine, so as to avoid air resistance in the cooling system, resulting in a decrease in the flow of the coolant, and finally the occurrence of diesel engine coolant. The phenomenon of boiling the pot.

Description

technical field [0001] The invention relates to a method for degassing a cooling system of a diesel engine, in particular to a method for removing air bubbles generated in cooling liquid during the operation of a heavy-duty diesel engine. Background technique [0002] Generally, the coolant of the diesel engine cooling system enters the water jacket of the cylinder head and the water outlet pipe successively from the water jacket of the cylinder block. Alternatively, the coolant of the diesel engine cooling system enters the water jacket of the cylinder body and the water jacket of the cylinder head respectively, and then enters the water outlet main pipe together. The coolant of this kind of diesel engine cooling system moves in the same direction as the air bubbles generated by the coolant during the operation of the diesel engine. The air bubbles are taken out of the cylinder block water jacket and cylinder head water jacket by the coolant, and collected in the water outl...
