The two-stage turbocharger includes a high-pressure turbocharger coupled to the exhaust manifold and a low-pressure turbocharger coupled to the high-pressure turbocharger. The high-pressure turbocharger is arranged on a side of the exhaust manifold. The low-pressure turbocharger is arranged above the exhaust manifold. An exhaust gas outlet of the high-pressure turbocharger and an exhaust gas inlet of the low-pressure turbocharger are coupled with each other through a flexible high-pressure exhaust gas pipe.
