Abstract

The invention discloses a connection structure between an intake manifold and an EGR system. One end of the intake manifold is used to connect with the throttle valve of the engine, and the other end of the intake manifold is used to connect with the intake valve of the engine. The pipe includes a manifold body and a connection assembly. The manifold body includes a plurality of intake branch pipes for communicating with the throttle valve respectively; The number of intake branch pipes is corresponding and connected to the connection hole. The connection cover protrudes away from the intake branch pipe to form a channel. The channels are respectively connected to the through hole and the connection hole. It is used to connect with the engine cylinder head and cover the intake valve. By opening a through hole on the connection cover, the EGR gas can flow directly from the through hole into the engine cylinder, so that the EGR gas flow into the engine cylinder is consistent and improves the efficiency of the engine.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a connection structure between an intake manifold and an EGR system. Background technique [0002] The engine is equipped with an intake valve and a throttle valve. The throttle valve is used to control the amount of gas entering the engine, and the intake valve is used to control the amount of gas entering the engine cylinder. [0003] At present, in order to improve the economy of the engine and reduce fuel consumption, EGR (Exhaust Gas Recirculation, exhaust gas recirculation) technology is usually used. EGR refers to reintroducing part of the exhaust gas discharged from the exhaust hole (or three-way catalytic converter) to the intake manifold. In the tube, part of the exhaust gas and fresh air are introduced into the combustion chamber for combustion. [0004] EGR in the prior art usually introduces the EGR gas drawn from the gas outlet of the three-way catalytic converter ...
