As EPA Tier 4 Final emissions regulations are being phased in, with final compliance due by 2015, we’re starting to see more and more engine manufacturers releasing new models that meet these stringent standards. Scania, a major worldwide supplier of industrial, commercial, military, and heavy-truck engines, has just announced a line of engines that meet EPA Tier 4 Final and EU Stage IV emissions without the need for a diesel particulate filter.
Saying Goodbye To DPFs
Scania’s DC Industrial line of engines includes both 9.0L and 13.0L inline-six cylinder engines, along with the 16.4L V-8. This engine family ranges in horsepower from 275 all the way up to 700. Developed in-house, the DC Industrial engines utilize Scania’s XPI (Extra High Pressure Injection) high-pressure common-rail fuel injection system and EMS engine management system. These sophisticated systems continually adjust to adapt to changing engine speeds and load situations. The XPI injection system utilizes a series of three injection events per cycle while injecting fuel at up to 34,809 psi.
In addition to the XPI common-rail fuel injection, the DC engines employ both exhaust gas recirculation (EGR), and selective catalytic reduction (SCR). Scania is utilizing a proprietary SCR system that was developed and tested in its laboratory in Sweden. Delivered with each engine is a diesel exhaust fluid (DEF) holding tank for the SCR system that holds either 38 or 60 liters of fluid and is heated using the engine’s cooling system to avoid freezing. End users provide their own exhaust piping to complete the system.
Making Power
The DC16 is the largest of the DC family of industrial engines, at 16.4L. In addition to the EMS engine management system, XPI common-rail injection, and emissions equipment, the engine comes with a host of premium features. Each engine is equipped with a single, fixed-geometry turbocharger; a fuel filtering system with an extra pre-filter and a water separator; centrifugal oil cleaner; an oil cooler that is integrated into the engine block; and a fuel heater. Blocks utilize wet cylinder liners that are easily changed, steel pistons are used for durability, and the engine has a single in-block camshaft and four valves per cylinder. The crankshaft is alloy steel with hardened and polished bearing surfaces and spins forged I-beam connecting rods. Each engine can be fitted by the end user with accessories such as air cleaners, silencers, PTOs, and flywheels to suit a plethora of different application needs. And these engines are designed to go a full 500 hours between oil changes.
