Multiquip 6212123320 Tip Nozzle SA6D140E

The Multiquip 6212123320 Tip Nozzle SA6D140E is a genuine OEM fuel injection nozzle tip designed for the DCA400SSK ultra-silent diesel generator. As a direct OEM replacement, this part is manufactured to the same specifications as the original component installed at the factory, ensuring proper fuel atomization and combustion performance in the SA6D140E engine. Sourced directly through authorized Multiquip supply channels, the part is the correct service part for DCA400SSK units requiring nozzle tip replacement.

Key Features

• Genuine OEM Fuel Injection Precision — Manufactured to exact OEM tolerances for the SA6D140E engine, ensuring correct spray pattern and fuel atomization critical to diesel combustion efficiency.
• Direct-Fit Replacement — Installs directly into the existing injector assembly on the DCA400SSK without modification, using the same mounting interface as the original component.
• Confirmed DCA400SSK Fitment — Verified for use with the Multiquip DCA400SSK ultra-silent diesel generator powered by the SA6D140E engine.
• Combustion Performance — A correctly functioning nozzle tip delivers consistent fuel delivery and spray geometry; a worn or damaged tip leads to misfiring, increased fuel consumption, and black smoke under load.
• Fuel System Integrity — Proper nozzle tip seating and spray control are essential for maintaining safe, stable diesel engine operation under generator load — making this a critical service part rather than a routine wear item to delay.

The tip nozzle is the terminal point of the fuel injector assembly, responsible for atomizing diesel fuel into a fine mist before it enters the combustion chamber. The shape, aperture, and condition of the nozzle tip directly control spray angle and droplet size, both of which affect how cleanly and completely the fuel burns. When a nozzle tip wears, corrodes, or becomes clogged, the result is poor fuel atomization — leading to hard starts, rough running, elevated exhaust emissions, and reduced power output from the generator.
