Woodward Electronic Controls and Software for Diesel Engines

733 Digital Control
Electronic controller for power generation, marine propulsion, and industrial engines

Woodward’s 733 digital control manages and controls reciprocating engines (gas, diesel, or dual fuel) used in power generation, marine propulsion, locomotive and industrial engine, and process markets. Specifically designed for direct mounting on the engine, the 733 can also be mounted inside control cabinets, if required.
The 733 is available in two configurations: as a standalone speed control or as the main control within an engine management system.  The control is designed for network connectivity to other Woodward or customer-selected devices, such as I/O modules (remote or integrated within the 733 package), actuators, ignition controls, air/exhaust and fuel flow control valves, power management controls, and EFI solenoid drivers. It may be programmed to perform all engine functions such as speed, air and fuel control, monitoring, alarms, engine protection, and sequencing.
The 733 is programmed using Woodward’s GAP - 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.

In-Pulse
The Woodward In-Pulse system has been developed to control a range of Woodward electrical low-pressure gas admission valves and electric-hydraulic high-pressure rail valves. These valves provide a means of injecting fuel or other fluids into engines operating within a speed range of 1 to 2100 rpm (range depends on the valve being driven). Plate type solenoid operated gas admission valves (SOGAVs) are suitable for in-manifold injection only, whereas the rail valve provides actuation of both in-cylinder and in-manifold type injection devices.

The Woodward In-Pulse II fuel injection control manages and controls electronically fuel injected (EFI) reciprocating engines (gas, diesel, or dual fuel) used in power generation, marine propulsion, locomotive and industrial engine, and process markets. The Woodward In-Pulse II manages the core fuel system and injection events for many EFI fuel systems, including electronic unit injectors and pumps (EUI/EUP), common rail systems (C-R), SOGAV Solenoid Operated Gas Admission Valves, micro pilot injection systems, and electronic rail valves (ERV). The Woodward In-Pulse II can mount directly on the engine, withstanding the high temperature and vibration environment. The Woodward In-Pulse II can also be mounted inside nearby control cabinets if required.

IKD 1 Digital I/O Expansion Board
The Woodward IKD 1 is an "Intelligent Terminal" or "Extension Board". It allows an additional 8 discrete inputs and 8 relay outputs to be connected, via CAN bus, to other Woodward products such as the Woodward GCP-30 Series controller. Each input can be assigned a name, alarm class, NO/NC configuration and time delay. The name and class are then displayed on the digital readout panel on the controller face. The Woodward IKD 1 output relays are controlled over the CAN bus connection from the main controller. Configuration for the Woodward IKD 1 is also accomplished from the main controller by a code entered via the controllers relay manager.

GAP Graphical Application Programmer
Woodward's Graphical Application Programmer (GAP) is a Windows based software program that allows controls engineers to create block format application programs for a number of Woodward control systems. Once the control logic is entered using the program's graphical programming environment, the GAP software compiler function generates code that runs in the control. GAP software blocks are written in C code, which is a transportable language, allowing it to be used on many different hardware platforms. Because of this feature, the same control logic software that has been used and proven in thousands of controls is available for use in the creation of future controllers, without introducing system bugs.

721 Digital Control (obsolete*)
The Woodward 721 Digital Control can share load between multiple engines driving a common mechanical or electrical load. It offers automatic bumpless transfer of load between engines and adjustable load and unload ramp rates. The control also provides a limiter to prevent engine overfueling or flooding during start-up. The Woodward 721 control governs gas or diesel reciprocating engines driving generators through flexible couplings. Using inputs from both the engine and generator sides of the coupling, the Woodward 721 control filters out torsionals in the speed signals, thus improving transient performance without sacrificing steady-state stability.
