The power of a double-cylinder engine in a low-power engine is 20-40 KW, the engine can be used in plateau, and the supercharger matching technology is not found in the industry at present. As more plateau areas of 2500m are located in China, the requirement of a 20KW low-power engine matched supercharger is more, and the requirement of the engine matched supercharger is more urgent especially when the engine is applied to national defense and satellite base stations.
The turbocharger in the turbocharger directly connects the turbocharger with the exhaust gas discharge part of the engine, and the turbine rotor assembly in the turbocharger is pushed to rotate by applying work through the exhaust gas power through the special flow channel of the turbocharger, so that the turbine rotor assembly is a main power source for applying work by using the exhaust gas of the engine, and the whole turbine rotor in the turbocharger is pushed to rotate at high speed and can rotate at more than 20 thousands of revolutions per minute.
However, because the traditional supercharger is widely matched with an engine with more than three cylinders, when the two-cylinder engine is matched with the supercharger, the two-cylinder engine has exhaust only 1/2 time. The engine exhaust flow is unstable up and down, and the traditional supercharger is unstable in working state due to periodic exhaust pressure rise and fall and intermittent conditions, so that the traditional supercharger cannot be matched and can achieve the performance suitable for the engine; it can be seen that the conventional supercharger has not been able to match a low power two cylinder engine.
