Delphi injector nozzles are precision-engineered components used in diesel fuel injection systems to atomize fuel into fine droplets for efficient engine combustion.
Key Types of Delphi Nozzles
· Common Rail Nozzles: Designed for modern electronic common rail systems to deliver precise fuel quantities, lower emissions, and enhance fuel efficiency.
· Mechanical / Conventional Nozzles: Used widely in older automotive, agricultural, and industrial diesel applications (such as Perkins and Caterpillar engines).
· Unit Injector Nozzles: Specialized tips built for integrated unit injector systems.
Main Functions
· Atomization: Breaks liquid diesel down into a fine mist so it mixes thoroughly with air.
· Spray Pattern Control: Directs fuel precisely into the combustion chamber to maximize power output.
· Flow Regulation: Opens and closes rapidly under high pressure to control injection timing and duration.
