Woodward developing new fuel injection systems
By Mike Brezonick01 March 2023
Global engine fuel injection system manufacturer Woodward has announced it is developing a comprehensive new range of injection systems applicable for large engines powered by new and future fuels, including methanol and ammonia.
Designed to support the global energy transition to low carbon fuels, the comprehensive portfolio of injection systems for P2X fuels in large engines will range from 134 to 1341 hp/cyl (100 to 1000 kW/cyl) to enable all possible combustion concepts.
For applications that require the highest levels of power density and efficiency, Woodward is developing a High-Pressure Dual-Fuel (HPDF) platform for methanol and ammonia injection with full diesel backup capability.
“The combustion engine industry is accelerating its efforts to decarbonize and switch from fossil fuels to alternative fuels produced from renewable sources (P2X) such as hydrogen, methanol and ammonia, and as a leading global injector manufacturer we need to ensure we have tailor made solutions for this transition” said Dr. Michael Willmann, director of Engineering - Large Engine Systems at Woodward.
“We are currently collaborating closely with engine OEM’s to design and test a range of injector systems that will meet the performance demands of new engines. Current development stages range from full field validation through to SCE and R&D phase with extremely positive results to date.”
Woodward said the new range of direct solenoid actuated injection systems is tailored to meet market requirements for simpler and retrofitted systems, including methanol injection systems for Port Fuel Injection (PFI) and Direct Injection (DI). The injectors are designed for optimal atomization of the fuel to enable good mixing and minimize wall wetting.
For gas engines that are adapted to run on gaseous P2X fuels such as hydrogen and ammonia, Woodward’s existing SOGAV gas admission valve technology is also being optimized to withstand the properties of these fuels such as poor lubricity, corrosion behavior and hydrogen embrittlement.
“There is a broad variety of combustion concepts for these fuels, and the best choice strongly depends on the target application for the user, whether they are in the marine and shipping sector, power generation or wider industry applications where these engines will be used,” Willmann said. “We are seeing the creation of a range of solutions to meet specific needs.”
