Problems solved by technology

Before the mixed gas enters the engine, it needs to be cooled by the intercooler. However, the temperature of the intercooler will be different under different operating conditions of the engine. Under high load conditions, the intake air temperature is relatively high. The air cooler is used for cooling, and under low load conditions, it is generally below 25%. At this time, the intake air temperature is low. If the low-temperature water enters the intercooler to cool the air at this time, the intake air temperature will be too low, which will affect the combustion efficiency.

Abstract

The invention belongs to the technical field of ship engine producing and manufacturing, and particularly relates to a cooling water bypass valve of an engine. The cooling water bypass valve comprisesa valve cavity. The valve cavity is provided with a water inlet for cooling water inflow and two water outlets for cooling water outflow, wherein the water outlets include the first water outlet andthe second water outlet. A valve element is arranged in the valve cavity and movably arranged in the valve cavity. The valve element moves in the valve cavity and can control the water inlet to selectively communicate with the first water outlet or the second water outlet. The first water outlet communicates with a water inlet of an engine intercooler, the second water outlet communicates with anengine body cooling water cavity, and the water inlet communicates with a water outlet of an engine cooling water pump. The bypass valve can selectively control the low-temperature water to flow intothe intercooler according to needs, the intercooler can cool air to the adaptive temperature according to needs of various work conditions, and the combustion efficiency of the engine is ensured.

Description

technical field [0001] The invention belongs to the technical field of marine engine production and manufacturing, and in particular relates to a cooling water bypass valve for an engine. Background technique [0002] In order to improve the combustion efficiency of marine engines, the inventors provided a new engine air supply method, that is, the air is mixed with the exhaust gas of the engine breathing system and then passed into the piston cylinder for combustion support. This air supply method can effectively improve the combustion efficiency of the marine engine. fuel combustion efficiency. Before the mixed gas enters the engine, it needs to be cooled by the intercooler. However, the temperature of the intercooler will be different under different operating conditions of the engine. The air cooler is used for cooling, and under low-load conditions, it is generally below 25%. At this time, the intake air temperature is low. If low-temperature water enters the intercool...
