In-Pulse II and ECM3 Fuel Injection Controllers

Precision fuel injection and engine control for gas, diesel, and dual-fuel engines

Woodward’s In-Pulse™ II and ECM3 fuel injection controls manage and control electronic fuel injection (EFI) reciprocating engines used in power generation, marine propulsion, locomotive, and industrial engine, and process markets.

The controllers manage the core fuel system and injection events for many EFI fuel systems, including electronic diesel unit injectors and pumps (EUI/EUP), diesel common rail systems (CR), solenoid-operated gas admission valves SOGAV™ , micro pilot injection systems, and electronic rail valves (ERV).

The controller mounts directly on the engine or it can be mounted inside a control cabinet, if required.

The In-Pulse II (with the addition of an 18-channel driver board), shares the same packaging, digital core, software tools, communication ports, I/O, and features of Woodward’s 733 Control. Therefore, where common engine types utilize different fuel systems, seamless interchangeability of the core fuel control can be easily accomplished without redesigning the complete engine management system.

Programming is fast and accurate with Woodward’s Graphical Application Programmer (GAP™). GAP is a dedicated, high-level, block-oriented programming language specifically designed for simple and quick implementation of difficult engine control strategies. GAP functions are easily modified and expanded, allowing fast creation of new applications.
