| Abgase der Industrie | waste industrial gases | |
| Abgasemission | waste gas emission (The direct or indirect discharge of exhaust gas into the atmosphere) | |
| Abgasemission | waste gas emission | |
| Abgasentgiftung | decontamination of waste gases | |
| Abgasentschwefelung | desulphuration of exhaust gases | |
| Abgasentschwefelung | flue-gas desulphurisation | |
| Abgasentstickung | denitrification of waste gas | |
| Abgasentstickung | denitrification of waste gas (Current methods for controlling NOx emissions in motor vehicles include retardation of spark timing, increasing the air/fuel ratio, injecting water into the cylinders, decreasing the compression ratio, and recirculating exhaust gas. For stationary sources, one abatement method is to use a lower NOx producing fuel or to modify the combustion process by injecting steam into the combustion chamber) | |
| Abgasfahne | exhaust plume | |
| Abgasfahne | plume | |
| Abgaskatalysator | catalytic converter (Catalytic converters are designed to clean up the exhaust fumes from petrol-driven vehicles, which are otherwise the major threat to air quality standards in congested urban streets and on motorways. Converters remove carbon monoxide, the unburned hydrocarbons and the oxides of nitrogen. These compounds are damaging to human health and the environment in a variety of ways. The converter is attached to the vehicle' s exhaust near the engine. Exhaust gases pass through the cellular ceramic substrate, a honeycomb-like filter. While compact, the intricate honeycomb structure provides a surface area of 23.000 square metres. This is coated with a thin layer of platinum, palladium and rhodium metals, which act as catalysts that simulate a reaction to changes in the chemical composition of the gases. Platinum and palladium convert hydrocarbons and carbon monoxide into carbon dioxide and water vapour. Rhodium changes nitrogen oxides and hydrocarbons into nitrogen and water, which are harmless) | |
| Abgasminderung | waste gas reduction | |
| Abgasminderung | waste gas reduction (Reduction of the quantity of gaseous emissions in the atmosphere, from motorvehicles, industrial and heating plants, etc. by the adoption of clean technologies, the effectiveness of process operations, the improvement of fuel quality and the installment of chimney stacks high enough to ensure the dispersion of gases) | |

| Abgasreinigungsanlage | abatement equipment | |
| Abgasreinigungssystem | flue gas cleaning system | |
| Abgasrückführung | exhaust gas recirculation | |
| Abgasrückführung | exhaust-gas-recirculation | |
| Abgasrückführungssystem | EGR system | |
| Abgasrückführungssystem | exhaust gas recycle system |
