Scania K-series

Coach Design bodied Scania K480 EB6X2NI Opticruise 300x180 Scania K seriesBusloversScania K-series is a series of bus with longitudinally, straight-up mounted Euro IV engine at the rear. For the 5- and 6-cylinder engines Scania is using exhaust gas recirculation (EGR) system to fulfill the legal Euro IV emission standard. The K-series is available with 9-litre 5-cylinder engines with output of 230 hp (1050 Nm), 270 hp (1250 Nm) or 310 hp (1550 Nm) as well as the 12-litre 6-cylinder engines with output of 340 hp (1700 Nm), 380 hp (1900 Nm), 420 hp (2100 Nm) or 470 hp (2200 Nm).
With Euro 5 emissions becoming mandatory in Europe in 2009, Scania have released upgraded engines in order to meet these regulations. The 5-cylinder DC9 engines feature a larger bore and displace 9.3-litres instead of 8.9-litres. The DC12 engines feature both a larger bore and a longer stroke, and therefore displace 12.7-litres instead of 11.7-litres. Most engines also receive slight performance improvements, for example the DC9 engine that outputs 310 hp/1550 Nm has been upgraded to 320 PS/1600 Nm.
The variants of K-series bus include coach, intercity bus and citybus chassis.
The K-series replaced the K94, K114, K124 and the L94 series (with the 60 degrees inclined-engine). source Wikipedia

Engine Technology Scania

Emisi Control Scania
Exhaust gas recirculation (EGR) reduces emissions during combustion, directly in the combustion chamber.
Scania EGR lowers nitrogen oxide emissions by cooling and reusing a portion of the exhaust gases. This leads to increased fuel efficiency without additives. Whether on the open road or in the city, Scania EGR effectively reduces emissions in all conditions.scania 300x93 Engine Technology Scania
Robust and proven aftertreatment system.

Scania SCR (selective catalytic reduction) is a proven aftertreatment system, which ensures that exhaust gases are released with a minimum of nitrogen oxide (NOx) content. By injecting a urea-based additive, AdBlue, into the exhaust, a chemical reaction takes place that converts the toxic nitrogen oxides into harmless water and nitrogen gas. A process that is straightforward and robust. scania1 300x87 Engine Technology Scania
