Description

technical field

[0001] The invention relates to an EGR system of an engine, in particular to a compact EGR channel structure. Background technique

[0002] As the international community pays more and more attention to environmental protection and energy utilization, vehicle engine emission regulations are increasingly stringent. Therefore, adopting more advanced engine technology to reduce emissions and CO2 emissions has become an important means for automobile and internal combustion engine manufacturers. Among them, EGR (Exhaust Gas Recirculation) technology has become an effective means to reduce emissions and fuel consumption, and is increasingly used in vehicle engines.

[0003] The vehicle EGR system structure mainly includes exhaust gas passage, EGR control valve and exhaust gas cooling passage. At present, EGR systems on the market mostly use complex piping systems or casting pipes to introduce exhaust gas into cylinder head air passages or intake manifolds to ach...
