Woodward’s SOGAV solenoid-operated gas admission valves are a family

of electrically actuated, high-response gas admission valves for in-manifold

(port) fuel admission. They are used on four-cycle, turbocharged,

natural gas or dual-fuel engines and are IGF-code zone “0” compliant.

Features & Functionality

The performance and characteristics of a gas and dual-fuel internal combustion

engine are significantly influenced by Gas Admission Valves (SOGAV).

Woodward’s SOGAV valves are a family of electrically actuated, high-response

gas admission valves for in-manifold (port) fuel admission.

They are used on four-cycle, turbocharged, natural gas or dual-fuel engines.

One SOGAV valve is required for each cylinder. The SOGAV valve is designed

as the valve portion of an overall gaseous fuel admission system delivering precise

gas mass flow-metering per cylinder. This enables gas engines and dual-fuel

engines to operate with lean burn – with increased efficiency and reduced emissions.

SOGAV valves provide reliable and precise control of gas fuel admission in multipoint

gas and dual-fuel engines. Woodward SOGAV valves are used in power generation,

marine, rail and mining vehicle applications. Available in gas mass flow-metering

capacities ranging from 70kw/cyl to 1500kw/cyl.

Self‐Diagnostics

The In-Pulse™ ll has integrated diagnostics to determine the control and IO integrity.

Memories, processor, IO, and baseline power supply monitoring are included in the diagnostic tests.

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.

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.

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 other Woodward 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.
