Embodiment Construction

[0014] As shown in Fig. 1 and Fig. 2, there is a water pump volute 2 integrated with the cylinder body by casting at the V angle in the middle of one side of the V-shaped engine cylinder block 8. The water pump 1 is installed in the water pump volute 2, and the two parts of the water pump 1 The left water channel port 3 of the water pump and the right water channel port 4 of the water pump are respectively connected to each other. Port 3 is slightly higher than water pump right channel port 4. The water jacket 5 on the intake side and the water jacket 6 on the exhaust side are composed of three connected cylinders of the same diameter, and the upper parts of the two cylinders have X-shaped water channels 7 connected at corners and the upper edges of the cylinders have interval distribution. The extension part 9 is formed.

[0015] As shown in Figure 3, between every pair of cylinder bores of the three cylinder bores 10 is the nose bridge area 11, and each cylinder bore 10 on ...

Abstract

A water-jacket and water-pump assembly of cylinder on engine in V form consists of two sets of water-jackets and water-pumps distributed at periphery of cylinder hole on said cylinder. It is featured as setting water-pump at V angle position in side-middle portion of said cylinder, arranging water channel opening at each side of water-pump and connecting these said opening separately to two sets of water-jackets distributed at periphery of cylinder hole.

Description

technical field [0001] The invention relates to an engine cooling system, in particular to a cylinder body water jacket and a water pump assembly of a V-type engine. Background technique [0002] At present, the V-type engine cylinder block has two sets of cylindrical cylinder holes, and cylinder water jackets through which cooling water flows are distributed around the cylinder holes. There is a water pump at the lower corner of the cylinder water jacket located on one side of the V-type engine cylinder block. The water inlet of the water pump is connected with the water jacket. When cooling, the water enters the group of cylinder water jackets connected with it from the water inlet of the water pump first. , and then flow through another set of cylinder water jacket. In this way, the flow distribution in the water jacket is uneven, the water pressure loss in the water jacket on both sides of the cylinder is also different, and the heat transfer coefficient is also differe...
