Bosch 0432217266 Diesel Fuel Injector Nozzle and Holder Assembly Direct Injection

The Bosch 0432217266 is a genuine OE diesel fuel injector nozzle and holder assembly designed for direct injection (DI) diesel engines. As a world-leading original equipment supplier of diesel fuel systems, Bosch engineers this nozzle-and-holder assembly to exacting OEM tolerances, ensuring consistent fuel delivery, proper spray pattern, and reliable combustion cycle after cycle.

The nozzle-and-holder assembly integrates the nozzle and nozzle holder into a single precision unit. Inside the nozzle holder, a compression spring acts on the nozzle needle via a pressure pin. During injection, fuel pressure lifts the nozzle needle off its seat, atomizing diesel fuel into the combustion chamber. The injection cycle ends when fuel pressure drops and the spring reseats the needle — a process that occurs with pinpoint timing hundreds of times per minute.

Key Features:

• Fuel Injector Type: Direct Injection (DI)
• Construction Material: Steel
• Number of Terminals: 1
• Genuine Bosch OE-quality component built to original manufacturer specifications
