Exhaust gas - Wikipedia
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, [1] or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle.
Exhaust gas recirculation - Wikipedia
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 …
What are the Car Exhaust Gases & Emissions? - Walker Exhaust …
Most modern internal combustion engine emissions are relatively harmless, so what are the harmful exhaust chemical compounds to be aware of?
What are the Health Effects of Exhaust Emissions? - News-Medical.net
2021年10月22日 · Exhaust emissions which result from internal combustion engines have become increasingly regarded as a potential health risk.
P0401 code – Exhaust Gas Recirculation Flow Insufficient Detected ...
2024年10月23日 · The Exhaust Gas Recirculation (EGR) system relies on a proper mixture of air and exhaust gases to function effectively. When the air filter is clogged, it restricts airflow into the engine. This limitation can lead to an imbalance in the combustion process. If there isn’t enough clean air for optimal combustion, the EGR system may struggle to ...
How Exhaust Gas Recirculation (EGR) system works
2019年10月3日 · The Exhaust Gas Recirculation or EGR system is one of several vehicle emission control systems. It helps reduce the amount of the nitrogen oxides (NOx) in the exhaust gases. Nitrogen oxides are normally formed in the process of combustion in the engine cylinders.
EGR Valve: What Is It and What Does It Do? - Cars.com
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 depending on how old the car is and...
Vehicle exhaust emissions | What comes out of a car exhaust?
Exhaust emissions are a mix of different gases and particles emitted by vehicles when the engine is running. These emissions can reduce the quality of the air around us, particularly in big cities that are congested with cars.
Exhaust system - Wikipedia
An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of the following: Cylinder head and exhaust manifold
Emission control system | Description, Components, & Facts
Emission control system, in automobiles, means employed to limit the discharge of noxious gases from the internal-combustion engine and other components. There are three main sources of these gases: the engine exhaust, the crankcase, and the fuel tank and carburetor.
