Effect of Diesel and Water Co-injection with Real-Time Control on Diesel Engine Performance and Emissions

From Delphi
 

 

A system for injection of diesel fuel and water with realtime control, or real-time water injection (RTWI), was developed and applied to a heavy-duty diesel engine. The RTWI system featured electronic unit pumps that delivered metered volumes of water to electronic unit injectors (EUI) modified to incorporate the water addition passages.
