Inter-cooling pressure-stabilizing system for single-cylinder engine turbosupercharger

The utility model provides an inter-cooling pressure-stabilizing system for a single-cylinder engine turbosupercharger. The inter-cooling pressure-stabilizing system comprises a single-cylinder engine and the single-cylinder engine turbosupercharger. A single-cylinder engine body is provided with a single-cylinder engine exhaust pipe and a single-cylinder engine air inlet pipe. A single-cylinder engine turbosupercharger body is provided with a supercharger tail gas inlet, a supercharger tail gas outlet, a supercharger air inlet and a supercharger air outlet. The single-cylinder engine exhaust pipe and the supercharger tail gas inlet are communicated through a first pressure-stabilizing device. The supercharger air outlet and the single-cylinder engine air inlet pipe are communicated through a second pressure-stabilizing device. An inter-cooler is arranged between the second pressure-stabilizing device and the supercharger air outlet. The single-cylinder engine turbosupercharger is connected with the independent lubricating system. The inter-cooling pressure-stabilizing system effectively stabilizes pulses, and enables air inlet and exhaust of the single-cylinder engine to be stable; the temperature in a cylinder is effectively lowered, and emission of nitrogen oxides is reduced.
