Integrated turbocharger and engine

The invention provides an integrated turbocharger and an engine, which can prevent condensed water from being generated at an EGR (Exhaust Gas Recirculation) valve, greatly reduce the corrosion rate of the EGR valve and prolong the service life of the EGR valve. The integrated turbocharger includes: a turbocharger shaft; the supercharger pressing end is arranged at one end of the supercharger rotating shaft; the supercharger vortex end is arranged at the other end of the supercharger rotating shaft; the supercharger vortex end comprises a volute rotationally connected with the supercharger rotating shaft, a turbine fixedly connected with the supercharger rotating shaft and an EGR valve integrated on the volute. The volute is provided with a vortex cavity for containing the turbine, an air inlet connector communicated with the vortex cavity and used for being connected with an exhaust chamber, an exhaust connector communicated with the vortex cavity and used for being connected with an exhaust pipeline, and an
