Engine block cross flow cooling circulation system

Abstract

The invention discloses an engine block cross flow cooling circulation system. The engine block cross flow cooling circulation system comprises a first main water channel, a cooler water jacket, a second main water channel and cylinder jacket water sleeves, wherein the water inlet end of the first main water channel is communicated with a water pump; the water inlet end of the cooler water jacket is communicated with the water outlet end of the first main water channel; the water inlet end of the second main water channel is communicated with the water outlet end of the cooler water jacket; and water inlets of the cylinder jacket water sleeves are respectively communicated with the second main water channel, so that engine cooling water of the second main water channel uniformly flows into the cylinder jacket water sleeves, thereby cooling the cylinder jackets. Water enters the engine cylinder jackets from the engine oil cooler water jacket to cool the cylinder jackets and then flows out upwards, thereby greatly enhancing the cooling uniformity of the cylinders. The engine block cross flow cooling circulation system improves the power performance, economical efficiency and emission of the engine, lowers the risk of boiling, and prolongs the service life of the engine.

Description

technical field [0001] The invention relates to the field of engine cooling systems, in particular to a body cross-flow cooling circulation system. Background technique [0002] The engine cooling system, after the coolant is pressurized by the water pump, flows through the body, passes through the oil cooler to cool the lubricating oil, and then enters the inner cylinder hole of the engine to cool the cylinder liner of each cylinder hole of the engine. The current commonly used cooling cycle passes through After the oil cooler enters the cylinder bore from the rear end of the engine block, it flows longitudinally forward from the jacket water jacket of the last cylinder to cool the cylinder liner cylinder by cylinder. Each cylinder is designed with a coolant outlet hole that flows upward to the cylinder head. The coolant flows out from the first cylinder at the front end to the cylinder head (each cylinder has part of the coolant flow out, and the total flow decreases gradu...

AI Technical Summary

Problems solved by technology

[0003] The existing technology mainly has the following problems: the coolant enters the cylinder jacket of each cylinder of the engine after passing through the water jacket of the cooler, and is cooled from the back to the front. The cooling efficiency of the rearmost cylinder is the best, and the cooling efficiency of the first cylinder is the worst. It is easy to cause the working state of each cylinder to be inconsistent with the combustion effect, which will have a certain impact on engine power, economy and emissions; and the cooling temperature of each cylinder is inconsistent, and the engine water temperature continues to rise. When the combustion temperature of each cylinder is roughly the same, The first cylinder cooler has the largest temperature rise and is most likely to boil over
