Applications

The PG-PL Governor is widely used for controlling speed for all types of diesel or gas

engines and steam turbines, driving pumps and compressors.

Standard Features

An internal oil pump, relief-valve, and accumulator system controls governor

operating pressure. A self-contained sump stores oil and reduces contamination from

outside sources.

Oil flow to and from the governor cylinder assembly is controlled by a centrifugal

flyweight-head and pilot-valve assembly. A power cylinder (servomotor) positions

the fuel racks, fuel valve, or steam valve of the engine or turbine.

A pneumatic (direct or reverse) operated bellows-type mechanism sets governor speed.

A knob on the governor provides a means of manual speed adjustment.

Governor stability is provided by an adjustable needle valve and spring-loaded

buffer compensation system.

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.

• 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.
