Method and device capable of preventing engine oil emulsification of gas engine

Abstract

The invention discloses a method and device capable of preventing engine oil emulsification of a gas engine, and the device capable of preventing engine oil emulsification comprises an electric control oil-gas separation device, a connecting plate, a high-temperature protection and power-off prevention device, an engine body, an oil return pipe, a power supply and energy storage device, a pressuresensor, a heating device, a temperature sensor and an oil pan. The electric control oil-gas separation device and the high-temperature protection and power-off prevention device are both installed onthe connecting plate, and the connecting plate and the pressure sensor are both installed on the machine body. The oil return pipe and the electric control oil-gas separation device are both connected with the machine body. The high-temperature protection and power-off prevention device is connected with the heating device through a wire. The method and device capable of preventing engine oil emulsification are suitable for the gas engine, intelligent control is achieved, the negative effect of engine oil emulsification caused by liquid water formed by condensation of combustion product watervapor of the gas engine can be quickly eliminated, the normal operation of the engine is ensured, and the engine oil replacement time of the engine is prolonged. Engine oil cost is reduced for a user, value is created for the user, and the problem of engine oil emulsification of an existing gas engine can be solved.

Description

technical field [0001] The invention belongs to the technical field of gas engines, in particular to a method and device capable of preventing emulsification of gas engine oil. Background technique [0002] At present, the gas generators on the market are CNG gas generators and LNG gas generators. The common feature is that a large amount of water and carbon dioxide are produced after combustion. Water is water vapor under high temperature conditions. It is discharged from the combustion chamber with the exhaust gas, and some of it leaks into the crankcase along with the exhaust gas. Inside, within 1 to 3 minutes after the engine is just started, because the temperature in the crankcase is relatively low, as long as it is lower than 60°C, the high-temperature water vapor will condense into water, and the water and engine oil will form oil emulsification after mixing, and the engine oil will turn white. , especially when the engine is started for 1 to 3 minutes and then shuts...

[0002] At present, the gas generators on the market are CNG gas generators and LNG gas generators. The common feature is that a large amount of water and carbon dioxide are produced after combustion. Water is water vapor under high temperature conditions. It is discharged from the combustion chamber with the exhaust gas, and some of it leaks into the crankcase along with the exhaust gas. Inside, within 1 to 3 minutes after the engine is just started, because the temperature in the crankcase is relatively low, as long as it is lower than 60°C, the high-temperature water vapor will condense into water, and the water and engine oil will form oil emulsification after mixing, and the engine oil will turn white. , especially when the engine is started for 1 to 3 minutes and then shuts down, or in low temperature places, the water vapor will condense more, which will cause the water content of the engine oil to exceed the standard! In places where the engine is far away from high temperature or relatively low temperature, local oil emulsification points will be formed
