Woodward OH-Series Engine Control Systems
Proven electronic control systems for gas- and propane-fueled,
medium- or heavy-duty vehicles
Woodward’s OH-Series engine control systems provide clean-burning engines, strong performance and outstanding fuel economy, essential to OEMs worldwide. Whether you’re running CNG (compressed natural gas), LNG (liquified natural gas) or LPG (liquid propane gas) in your medium- or heavy-duty vehicle, Woodward has a control solution for you.
Our integrated system of electronic controls, sensors, valves, and actuators work together to control precisely the air flow, fuel flow, exhaust flow, and combustion processes of the engine. This helps the engine meet mandated emissions levels with the fuel economy and reliability vehicle operators demand.
Operating under an OH system, an engine can meet any targeted emissions level from Euro 2 to Euro 6 (or equivalent) while maintaining diesel-like drivability and excellent fuel economy.
Woodward has extensive experience and knowledge in designing complete system solutions for any application. And, our global network of local Woodward engineering centers provides superior engineering and product support.
