The 2014 Navistar N13 engine with SCR (Selective Catalytic Reduction) is a powerful and efficient diesel engine designed for heavy-duty trucks. It boasts a displacement of 12.4 liters and utilizes a common-rail fuel injection system, delivering high torque output and smooth performance across a wide range of operating conditions. The N13 engine's SCR technology further enhances its environmental friendliness by reducing nitrogen oxide (NOx) emissions through the use of an exhaust aftertreatment system. This system injects a urea solution into the exhaust stream, where it reacts with NOx to convert it into harmless nitrogen gas and water vapor. The engine is also equipped with features like an electronic control module (ECM) and variable geometry turbocharger (VGT) to optimize performance and fuel efficiency.
