The invention discloses a high-pressure exhaust gas recirculation (EGR) system of a vehicle engine and relates to an EGR system. The high-pressure EGR system of the vehicle engine passes through the engine, wherein the engine is provided with a gas inlet and a gas outlet and comprises a gas inlet pipeline, a gas outlet pipeline, an EGR pipeline and an electronic pressurizer. The gas inlet pipeline is arranged in front of the gas inlet. The gas outlet pipeline is arranged behind the gas outlet. The ERG pipeline is connected between the gas inlet and the gas outlet pipeline of the engine and used for conducting ERG on part of gas exhausted by the gas outlet pipeline and then sending the exhaust gas to the engine again. The electronic pressurizer is arranged on one side of the gas inlet pipeline through a pipe. The electronic pressurizer is arranged on the gas inlet pipeline of the high-pressure EGR system, so that parts are fewer, the application cost is low, and the arrangement difficulty is relatively low; and actuators needing to be controlled are fewer, so that calibration is easy to conduct, the oil-saving effect of the electric pressurizer and the high-pressure EGR technology which are applied to a pressurizing gasoline engine is improved, and application of the electric pressurizer and the high-pressure EGR technology to the pressurizing gasoline engine is promoted.
