Key Product Variants Include

• Medium-Pressure Injection Family (MPI)

• High-Pressure Dual-Fuel Family (HPDF)

Features & Functionality

The Medium Pressure Injection (MPI) product line features a direct actuated technology

for port fuel injection or medium pressure direct injection. 

The family supports different fuels and combustion strategies and offers liquid fuels

(methanol, ethanol or ammonia) and gaseous fuels (hydrogen) injection with electronically

controlled Common Rail technology, up to 250 bar injection pressure.

The injectors can be customized to match every engine’s requirement in terms of nozzle positioning,

fuel inlet, and packaging while maintaining high commonality with the family.

The High-Pressure Dual Fuel (HPDF) product line features a twin nozzle concept,

with two injectors in one unit: one side for ammonia or methanol injection up to 700 bar

injection pressure with electronically controlled Common Rail technology,

the other side for diesel injection for pilot-ignition or full back-up capability.

The diesel-side is offered with mechanical injection (pump-line-nozzle technology, PLN) 

or state of the art Common Rail Technology, customized to engine requirements.

The twin-needle dual fuel injector concept is much easier to integrate into a cylinder

head compared to two separate injectors with the advantage of both nozzles being in the

center of the cylinder for optimized combustion. The modular approach enables adaptation

of the design to match individual customer requirements.

Woodward is committed to supporting the global transition to low carbon fuels and

helping its customers meet the performance demands of new engines.

The company has been working closely with engine OEMs to develop and validate the new product lines.

Key Product Variants Include

• Customized to every application’s unique requirements.

• Made for remanufacturing to save costs and protect the environment.

• Drift compensation, condition monitoring, digital identification of components and a load

recorder rank among the basic functions that can be implemented.

• Smart injector technology makes a significant contribution to ensuring compliant emissions

over the entire effective life of a fuel injection component.

• The smart injectors are service-oriented and user-friendly in practice: they enable simple,

fast system analysis and clear, accurate error identification.

The L’IQ Intelligent Injector ensures optimized utilization of fuel injection components over time.

The new L’IQ injectors are configured to be smart and communicate with their environment.

This opens up the potential for a number of components within a system to exchange data and

information,which in turn will lead to optimization of the entire system, sub-systems or superordinate

systems.

In the future, fuel injection along with combustion will be monitored by electronic systems.

This will enable the thermodynamic optimization of combustion based on fuels with

strong variations in characteristics, as well as the early detection of unforeseen

fuel injection behavior or even engine failure.

With the intelligent injector, the cornerstone is being laid for the digitalization of individual fuel

injection components – and for the ongoing evolution of integrated injection technology.

We have developed a High-Pressure Dual-Fuel (HPDF) and a Medium-Pressure (MPI)

Injector Family that are ready to handle many different fuel options.

They can even effectively deal with fuel switches during an engine’s lifetime.

This state-of-the-art injector technology enables the use of most greenhouse-gas-reducing

P2X fuels (Power-to-X fuels) currently under discussion.

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.
