FIELD: machine building.
SUBSTANCE: claimed group of inventions relates to engine building, namely to spent gas recirculation diffusers. Exhaust gas recirculation system (EGR) for internal combustion engine (10) comprises air intake channel (46) configured to supply inlet air to internal combustion engine (10). EGR diffuser (50) configured to supply recycled exhaust gases from internal combustion engine (10) to air intake channel (46) through outlet channel. At that, EGR diffuser (50) comprises a body part, a movable element movable relative to the body part. Movable element is made with possibility to change sizes of outlet channel. Movable element comprises pressure surface installed so that at least inlet air or recirculated exhaust gases act on pressure surface causing movement of movable element in first direction and change of dimensions of outlet channel. Movable element is configured to displace in the second direction. Vehicle is also disclosed.
EFFECT: technical result is enabling more uniform mixing of recirculated exhaust gases in a wide range of engine operating conditions.
