Abstract

The invention relates to an air intake system for an engine of a vehicle, which comprises a compressor inlet pipe installed to connect an EGR valve to an inlet of a compressor of a charger and is made of a thermally conductive material; a gas pocket formed at the compressor inlet pipe; a gas supply device configured to draw gas from an outlet of the compressor of the charger and supply the gas to the gas pocket; and a gas discharge device configured to discharge the gas in the gas pocket.

Description

technical field [0001] The present disclosure relates to an engine intake system of a vehicle, and more particularly, to a technology related to an intake system including a charger. Background technique [0002] A supercharger for an engine may be used to compress air and supply the compressed air to a combustion chamber to improve the boosting efficiency of the engine and thereby increase engine power. The supercharger can be divided into a turbocharger and a supercharger (supercharger), wherein the turbocharger is driven using exhaust gas discharged from the engine, and the supercharger is driven using a separate motor such as an electric motor. power source to drive. In many cases, engines include exhaust gas recirculation (EGR) devices for recirculating a portion of exhaust gases through the engine intake system to the combustion chambers to reduce emitted nitrogen oxides and improve fuel efficiency. [0003] In addition, blow-by gases generated in the engine may be c...
