In-Pulse II and ECM3 Fuel Injection Controllers

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

    In-Pulse II Digital Control    ECM3 

    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.

    • Controls up to 18 outputs
    • Multiple sensor detection options
    • Redundant speed sensor options
    • Up to 7 injection events per cylinder
    • Programmable current profiles for each injection event
    • Woodward GAP™ programming environment
    • Redundant single propulsion marine configurations
    • CSA and CSAUL listed
    • CE Compliant  
    The In-Pulse II or ECM3 controllers can be used as the main control unit within an engine management system. The controls are designed for network connectivity to other Woodward or customer-selected devices, such as:
    • remote I/O modules
    • actuators
    • ignition controls
    • air/exhaust and fuel flow control valves
    • power management controls 

    The controls can be programmed to perform all engine functions such as speed, air and fuel control, monitoring, alarms, engine protection, and sequencing.

    The In-Pulse II improves engine management or plant control system reliability by offering many redundant options, including redundant networks, redundant speed and position sensors, redundant power supply inputs, and a second In-Pulse II wired as a hot stand-by for critical applications or where marine classification requires it.
