Injection Systems Support Transition to PX2 Fuels

March 16, 2023
Woodward is developing a portfolio of injection systems for P2X fuels for large engines to enable all possible combustion concepts.

A portfolio of injection systems for P2X fuels in new and future fuel-powered engines including methanol and ammonia support the global energy transition to low-carbon fuels. The systems for large engines will range from 100 to over 1,000 kW/cylinder 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 range of direct solenoid actuated injection systems meet 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, SOGAV gas admission valves are also being optimized to withstand the properties of these fuels such as poor lubricity, corrosion behavior, and hydrogen embrittlement.
