The exhaust gas recirculation (EGR) tube diverts gases from the exhaust manifold through the EGR system for burning in the combustion chamber. The symptoms of a faulty EGR tube are rough idling, stalling, knocking sounds, and an illuminated check engine light.

EGR:全称为排气再循环（Exhaust Gas Recirculation），内燃机在燃烧后将排出气体的一部分分离出、并导入进气侧使其再度燃烧的技术（手法或方法）。主要目的为降低排出气体中的氮氧化物（NOx）与分担部分负荷时可提高燃料消耗率。 EGR工作机理

In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1] EGR works by recirculating a portion of an engine's exhaust gas back to …

Integral to the vehicle’s engine management system, the aptly named exhaust gas recirculation valve, or EGR valve for short, recirculates finely metered quantities of exhaust gas to the engine intake system for increased engine efficiency, reduced fuel …

2019年10月3日 · The EGR system reduces the combustion temperature by diverting a small portion of the exhaust gases back into the intake manifold. How does it work? Exhaust gases are no longer combustible.

2020年9月19日 · EGR stands for exhaust gas recirculation, a vehicle emissions control concept used in both gasoline and diesel engines. The EGR valve — which works differently …

Tutorial on the main components of the EGR system, principle of operation, advantages and disadvantages: EGR valve, EGR cooler and EGR intake throttle.

2016年10月4日 · The EGR valve is connected to an EGR pipe, which helps distribute molecules through your vehicle’s EGR system. A bad pipe leads to performance issues.

Maintaining a clean EGR tube ensures peak engine performance and reduces harmful emissions. By ensuring proper exhaust gas recirculation, a clean EGR tube plays a crucial role in decreasing the emissions that contribute to air pollution.

To change an EGR valve on most types of vehicles, you’ll need the following tools and items: Ratchet and sockets for removing bolts and nuts; Torque wrench to ensure proper bolt tightening; Gasket scraper or knife to remove old gasket materials; New EGR valve for your specific model and engine size; New gasket to seal the new EGR valve to the ...
