An engine block cooling guide system

Abstract

The invention provides an engine cylinder cooling flow guide system which comprises a cylinder body and a flow guide tube, wherein a water inlet and a water outlet are formed in the cylinder body; cylinder tubes are arranged in the cylinder body; the water inlet is close to an exhaust side of the cylinder body; the water outlet is close to an air inlet side of the cylinder body; one end of the flow guide tube is fixedly connected with the water inlet, and the other end of the flow guide tube is closed and is fixed on one side, relative to the water inlet, of the cylinder body; and a plurality of flow guide holes are formed in the side wall of the flow guide tube. According to the engine cylinder cooling flow guide system, through arranging the flow guide tube in the cylinder body, one end of the flow guide tube is connected with the water inlet of the cylinder body, and the other end of the flow guide tube is closed and is fixed in a water sleeve of the cylinder body; and the flow guide holes are transversely formed in the flow guide tube, and cooling water flows into the flow guide tube and then flows out simultaneously via the flow guide holes, so that the cylinder tubes are cooled simultaneously to ensure consistency of thermal deformation of the cylinder body and further optimize combustion and oil consumption of an engine.

Description

Technical field [0001] The invention relates to the field of engines, in particular to an engine cylinder block cooling and diversion system. Background technique [0002] As one of the important components of the engine, the cooling system meets the cooling requirements of various parts of the engine. Among them, cylinder cooling is the most important and important part of the engine cooling system. In the prior art, after being pressurized by a water pump, cooling water directly enters the water jacket of the cylinder block from the front end of the engine, and sequentially passes through the cylinders of the engine to cool the cylinder block. [0003] As the cooling water flows in from the water inlet of the cylinder block and flows out from the water outlet of the cylinder block, heat will be dissipated in the combustion chamber of the cylinder block during the period, resulting in inconsistent temperature of the cooling water flowing through the water jacket of each cylinder,...

AI Technical Summary

Problems solved by technology

[0003] Since the cooling water flows in from the water inlet of the cylinder block and flows out from the water outlet of the cylinder block, it will dissipate heat to the combustion chamber of the cylinder block during this period, resulting in inconsistent temperatures of the cooling water flowing through the water jackets of each cylinder, which is close to the temperature of the cooling water at the front end of the engine Low, the temperature of the cooling water away from the front end of the engine is high, resulting in inconsistent cooling temperature of each cylinder of the engine block, resulting in inconsistent thermal deformation of the block, affecting the fit gap between the piston ring and the block, and deteriorating the combustion and oil consumption of the engine
