Exhaust emissions are measured using a 2013 model year AVL iGem i60 CVS dilute emissions bench. The bench is capable of measuring tailpipe exhaust emissions produced by gasoline and diesel engines. The AWD dynamometer Test Cell temperature can be set for vehicle testing between 20F (-6C) and 100F (38C). [6]
A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]
The NTE cap is set at 1.25 times the FTP emission limit as described in the subsection above. For 2005 model year heavy-duty engines, the NTE emission cap for NMHC plus NOx is 1.25 times 2.5 grams per brake horsepower-hour, or 3.125 grams per brake horsepower-hour. The basic NTE control area for diesel engines has three basic boundaries on the ...
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
Grade 2 diesel fuel is available with 2 different sulfur levels depending on the population density of the location where it is retailed. Grade 3 diesel fuel, also known as GASOIL ULTRA, is the highest quality diesel fuel and is supposed to be available starting February 1, 2006. Sale of Grade 3 diesel at retail outlets is optional until 2008.
Test cycles specify the conditions under which the engine or vehicle is operated during the emission test. There are many different test cycles issued by various national and international governments and working groups. [1] Specified parameters in a test cycle include a range of operating temperature, speed, and load. Ideally these should ...

More efficient design. Longer service life. Fuel savings. Ultra-low emissions. Improved wheel to rail adhesion capability. With multiple engine gensets, should one genset engine fail, the others can keep the train going, albeit at reduced speed.
