Diesel engine emissions regulations have historically been directed at the manufacturer level and the development of technologies have not only lowered emissions but also provided end-users with additional power, fuel efficiency and production our of the equipment. The Tier IV emissions levels and ...
The improvement of air quality requires a further reduction of pollutant emissions, especially in urban areas. The Euro 7 regulations aim at the developmen... T Kossioris,R Maurer,S Sterlepper,... - 《Emission Control Science & Technology》 被引量: 0发表: 2024年 Strategies for emission contr...
Regulatory Acts.Emissions from marine diesel engines (compression ignition engines) have been regulated through a number of rules—the first one issued in 1999—applicable to different engine categories. Certain overlap also exists with the regulations for mobile, land-basednonroad engines, which may ...
The transient operation of turbocharged diesel engines can prove quite demanding in terms of engine response, systems reliability and exhaust emissions. It is a daily encountered situation that drastically differentiates the engine operation from the respective steady-state conditions, requiring careful and...
With respect to their emissions, today's diesel engines are considered as feed-forward controlled systems. To meet the emission regulations for the entire lifetime of an engine despite sensor and actuator drift, developers introduce certain design tolerances. However, future emission regulations leave ...
3. Diesel industry confronts the emissions settlement: the engine technical landscape changes again, as EPA hits diesel hits diesel industry with emissions "cheating" settlement; timing of standards move up, hello EGR & aftertreatment? [J] . Mike Osenga Diesel ...
Scientific consensus asserts that global greenhouse gas (GHG) emissions must be reduced by 45% from 2010 levels by 2030 to limit global warming to 1.5 °C and minimize climate catastrophe1. The US freight rail sector provides a unique opportunity for aggressive near-term climate action. It tr...
Gaseous emissions were measured at the exhaust. Lower exhaust emissions were measured when the engine runs with pure RME with respect to diesel fuel in terms of CO, HC, NOx, PM and particle number. From the analysis of the data it can be argued that a proper engine calibration could ...
Average ammonia emissions are not to exceed 25 ppm for engines with SCR aftertreatment; If the engine is equipped with a vanadium containing SCR catalyst, data demonstrating that vanadium emissions will not occur during the useful life is required and SCR inlet temperatures above 550°C are not ...
The influence of fuel aromatics type on the particulate matter (PM) and NOx exhaust emissions of a heavy-duty, single-cylinder, DI diesel engine was investigated. Eight fuels were blended from conventional and oil sands crude oil sources to form five fuel pairs with similar densities but with ...
