Woodward In-Pulse ll Fuel Injection Control

The in-Pulse ll manages the core fuel system and injection events for many EFl fuelsystems,

including electronic unit injectors and pumps (EUl/EUP), common railsystems (C-R),

$OGAV™ Solenoid Operated Gas Admission Valves, micro pilotinjection systems,

and electronic rail valves (ERV).The In-Pulse ll can mount directly on the engine,

withstanding the high temperatureand vibration environment.

The In-Pulse ll can also be mounted inside nearby controlcabinets if required.

The In-Pulse ll, with the addition of an 18-channel driver board, uses the samepackaging,

digital core, software tools, communication ports, l/O, and features of the733 Digital Control.

Therefore where commonengine types utilize different fuel systems,

seamless interchangeability of the corefuel control can be easily accomplished

without redesigning the complete enginemanagement system.

If required, the In-Pulse ll can be used as the main control unit within an enginemanagement system.

The control is designed for network connectivity to otherWoodward or customer-selected devices,

such as remote l/O modules, actuators.ignition controls, air/exhaust and fuel flow control valves,

and power managementcontrols.it may be programmed to perform all engine functions such as speed,

airand fuel control, monitoring, alarms, engine protection, and sequencing.

The In-Pulse ll improves engine management or plant control system reliability byoffering many

redundant options, including redundant networks, redundant speedand position sensors,

redundant power supply inputs, and a second In-Pulse ll wiredas a hot stand-by for critical

applications or where marine classification requires it.

Because of the many philosophies with respect to sensing speed and crank position,

the control incorporates multiple sensing algorithms that include missing tooth andpin

detection on the crank or cam for sensing speed and crank position.

lf sensorfailure protection is required, redundant sensors can be employed.

Programming

The In-Pulse ll is programmed using Woodward’s proven GAP™ Graphical Application Programmer.

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.

Adjustments

Adjustments can be made quickly and easily through the Woodward Watch Window or Control

View PC configuration interfaces. Both adjustment methods are menu-driven.

The control saves all set points to non-volatile memory uponcommand.

Communications

The In-Pulse ll provides two isolated serial interfaces—one RS-232 and the other RS-485.

Both ports feature an industry-standard Modbus® * protocol (ASCII or RTU) that can interface

to a Modbus master or slave device such as a Human/Machine Interface (HMI).

These ports also support Woodward ServLink protocol for a Watch Window or Control View PC interface.

Baud rates are tunable to meet specific user requirements.

The In-Pulse ll also provides three CAN ports, one of which is isolated if requested.

All ports feature J1939 and CANOpen protocols. These ports can be used for distributed

control with other devices such as actuators, valves, other In-Pulse ll controls and 733’s 

(to load share for example), and to communicate with other on-engine devices such as I/O

modules and displays.

The isolated port is well suited for communication to off-engine components like PLCs,

ship and building systems.
