Problems solved by technology

But there is a problem: in the process of lateral flow of coolant, the temperature gradually rises, which will lead to poor cooling effect in the area far away from the water inlet, and there is also the problem of insufficient cooling in the high temperature area. The cooling water jacket of this structure restricts Further increase in engine temperature; more complicated structure and higher manufacturing cost

Abstract

The invention discloses an engine cooling water jacket comprising a cylinder body water jacket and a cylinder cover water jacket. The cylinder cover water jacket includes a first auxiliary water outlet, a second auxiliary water outlet and three sets of cooling liquid inlets at the air exhaust side of a cylinder cover, and three sets of cooling liquid outlets at the air inlet side of the cylinder cover. Each set of cooling liquid inlets and the corresponding set of cooling liquid outlets correspond to one cylinder. Each cylinder corresponds to one cylinder cover air exhaust duct area and one cylinder cover inlet duct area. The nose bridge area in the middle of each cylinder cover air exhaust duct area is provided with a cooling water channel. Two partitions are arranged in the cylinder body water jacket to divide the cylinder body water jacket into an air exhaust side cylinder body water jacket and an air inlet side cylinder body water jacket. The front of the air exhaust side cylinder body water jacket is provided with a main water inlet, the bottom of the front end of the air inlet side cylinder body water jacket is provided with an auxiliary water inlet, and the rear end of the air inlet side cylinder body water jacket is provided with a main water outlet. The engine cooling water jacket of the invention enables all parts of an engine to cool uniformly.

Description

technical field [0001] The invention belongs to an automobile engine cooling system, in particular to an engine cooling water jacket. Background technique [0002] The engine cooling water jacket is composed of a cylinder block water jacket and a cylinder head water jacket. At present, there are two common cooling water jacket arrangements: [0003] 1. After being pressurized by the water pump, the coolant enters the water jacket of the cylinder block, flows through the water hole of the cylinder head gasket, enters the water jacket of the cylinder head, and then flows out of the engine body through the water jacket of the cylinder head. This kind of water jacket has a simple structure and is easy to control, but for Ensure that the temperature of each cylinder of the engine is similar, resulting in the change of the water hole on the cylinder gasket with the increase of the distance from the water pump, the flow rate uniformity in the water jacket is poor, and the cooling e...
