Control method and device of stroke injection engine for reducing lubricating oil consumption. According to the current locomotive engine is still in the traditional carburetor engine, the fuel entering the combustion chamber uses the throttle opening of the air intake device to allow outside air to enter, and the vacuum attraction generated by the air is also at the throttle. At the same time, the fuel in the carburetor is brought into the combustion chamber for combustion, and the lubricating oil required for components such as pistons and connecting rods is also brought into lubrication by the air intake device. For the lubrication process, please refer to the first Figure, which is a schematic diagram of the conventional lubricating oil lubrication process (Figure, as shown in the figure, when the lubricating oil is injected into the air intake device 11, the lubricating oil, air and fuel are mixed in the air intake device 11 and flow to The crankcase 12 reaches the combustion chamber 14 and burns along the drive channel 13 and exhausts the burned gas. However, although this method can achieve the effect of lubricating the internal components of the engine, it still has the following shortcomings in practice. It is worth improving: 1. Poor lubricating effect: As soon as the lubricant enters the air intake device, it is mixed with air and fuel and enters the crankcase. At this time, the fuel easily causes the lubricant to have a washing effect and greatly reduces the lubrication. The viscosity of the lubricant affects the lubricating effect of the lubricating oil. At the same time, after the lubricating oil is dissolved in the fuel oil, it is more likely to emit white smoke during combustion, which will adversely affect the air quality. 2. Large consumption of lubricating oil: Xi Know that the lubricant of the locomotive is supplied as soon as the engine is running.
