Dr Klaus Harth, responsible for research on automotive catalytic converters at BASF, remarks: "Catalytic converters are now capable of removing considerably more than 95 per cent of the undesired substances from the exhaust gas
An Automotive News 2015 PACE Award finalist, BorgWarner's new exhaust gas
recirculation (EGR) module is the first EGR module designed specifically for gasoline engines.
Among the features enabling this engine to comply with Tier 4 interim exhaust emission standards are an external exhaust gas
recirculation system and a diesel particulate filter with active regeneration.
The air intake throttle valve controls the amount of air entering the engine and the EGR valve controls the amount of exhaust gas
to be recirculated into the engine.
Nitrogen oxide enters the catalyst in the exhaust gas
, and is selectively reduced to nitrogen and water.
Fine substances based on carbon (C) contained in the exhaust gas
from diesel engines.
recirculation (EGR) technique involves NOx abatement during the combustion process.
Inside the container is a porous ceramic structure through which the exhaust gas
They've also developed a low-pressure EGR system, which extracts exhaust gases
downstream of the particulate filter, then returns them upstream of the turbocharger (as contrasted with the high-pressure EGR, which extracts exhaust gas
upstream of the turbocharger and reroutes it to the intake system downstream of the compressor).
The DF300 meets exhaust gas
emission criteria of both the American Environmental Protection Agency (EPA) and the Japan Boating Industry Association.
Other companies introduced engines with various forms of exhaust gas
recirculation (EGR), a process that returns exhaust gases
to the combustion chamber.
Modine Manufacturing Company recently announced that its Joplin, MO facility has produced its millionth exhaust gas
recirculation (EGR) cooler.
Sensors within the motor provide feedback to a closed-loop control system to position the valve and ensure precise control of recirculated exhaust gas
today announced it has developed a next-generation diesel engine that reduces exhaust gas
emissions to a level equal to a gasoline engine.
As a result, there is an emergence of new exhaust systems technologies for both diesel engines such as close-coupled diesel particulate filters, NOx traps, and clean exhaust gas
