Maceió Urban Rail (Portuguese : Sistema de Trens Urbanos de Maceió) is the 32.1-kilometre (19.9 mi) metre gauge diesel commuter rail line that serves the city of Maceió, Alagoas, Brazil. The line connects Maceió with two cities in the metropolitan area, Satuba and Rio Largo (the line's northern terminus). [1]
Portuguese is a Western Romance language originating in the Iberian Peninsula. It is the sole official language of Portugal, Brazil, Cape Verde, Guinea-Bissau, Mozambique, Angola, and São Tomé and Príncipe. It also has co-official language status in East Timor, Equatorial Guinea and Macau in China. As the result of expansion during colonial times, a cultural presence of Portuguese and Portuguese creole speakers are also found in Goa, Daman and Diu in India; in Batticaloa on the east coast of Sri Lanka; in the Indonesian island of Flores; in the Malacca state of Malaysia; and the ABC islands in the Caribbean where Papiamento is spoken, while Cape Verdean Creole is the most widely spoken Portuguese-based Creole. Reintegrationists maintain that Galician is not a separate language, but a dialect of Portuguese. A Portuguese-speaking person or nation is referred to as "Lusophone" (Lusófono).
The Diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel, which is injected into the combustion chamber, is caused by the elevated temperature of the air in the cylinder due to the mechanical compression. Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised Diesel fuel injected into the combustion chamber ignites spontaneously. With the fuel being injected into the air just before combustion, the dispersion of the fuel is uneven; this is called a heterogenous air-fuel mixture. The process of mixing air and fuel happens almost entirely during combustion, the oxygen diffuses into the flame, which means that the Diesel engine operates with a diffusion flame. The torque a Diesel engine produces is controlled by manipulating the air ratio; this means, that instead of throttling the intake air, the Diesel engine relies on altering the amount of fuel that is injected, and the air ratio is usually high.
Commuter rail, also called suburban rail, is a passenger rail transport service that primarily operates between a city centre and middle to outer suburbs beyond 15 km and commuter towns or other locations that draw large numbers of commuters—people who travel on a daily basis. Trains operate following a schedule at speeds varying from 50 to 225 km/h. Distance charges or zone pricing may be used.
