[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 t

Example Embodiment
[0028] Example 1:
[0029] This example gives a device that prevents emulsification of gas machine oil, such as Figure 1-5 As shown, including the electronically controlled oil and gas separation device 1, the connecting plate 2, the high temperature protection and the power distribution device 3, the body 4, the return pipe 5, the power supply device 6, the pressure sensor 7, the heating device 8, the temperature sensor 9 and oil The bottom case 10, wherein the electronically controlled oil gas separation device 1 and the anti-high temperature protection and the power off device 3 are mounted on the connecting plate 2, and the connecting plate 2 and the pressure sensor 7 are mounted on the body 4;
[0030] The oil return pipe 5 and the electronically controlled oil gas separation device 1 are connected to the body 4;
[0031] The high temperature protection and power-off device 3 and the heating device 8 are connected by a wire;
[0032] The oil base case 10 is mounted below the ...
Example Embodiment
[0040] Example 2:
[0041] This example gives a method of preventing gas engine oil emulsification, the specific steps are as follows:
[0042] S1, the system is pre-designed with the electronically controlled oil and gas separation device 1 working procedure;
[0043] S2, the electronically controlled oil and gas separation device 1 is activated, and the water vapor inside the engine quickly discharges the outer surface of the crankcase;
[0044] S3, when the pressure sensor 7 is induced to the crankcase pressure reaches -2kPa, the electronically controlled oil gas separation device 1 stops, when the pressure rises, the electronically controlled oil and gas separation device 1 starts working until the auxiliary exhaust of 3 minutes is completed;
[0045] S4, when the engine stops, due to the delay operation setting of the system, the electronically controlled oil gas separation device will continue to work for 3 minutes until the residual gas in the crankcase is emptied, and the ...

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...
