Based on a half-century of expertise controlling diesel locomotive engines, Woodward offers a wide range of technologies that enhance reliability, performance and emissions. A variety of diesel fuel injection technologies, from simple mechanical injection to the latest in low-emissions, high-pressure common rail systems, provide reliable service. Electronic engine controls and rapid control system development tools interface with locomotive control systems to optimize performance and efficiency. Actuation and valve technology can precisely control exhaust gas flow, turbocharger boost pressures, air flows, and other processes to improve power output, efficiency, and emissions. Aftertreatment control units provide automatic regeneration of particulate filters and dosing control.
