Here is the breakdown and specification for the 37560-07800 / DL160T2910NP47E fuel injector nozzle tip for a Mitsubishi diesel engine.
Summary
This is a pintle-type nozzle (often referred to as a "long cap" or "long tip" nozzle) commonly used in Mitsubishi heavy-duty diesel engines, particularly in the 6D22, 6D24, and 6D40 series.
Part Number Breakdown
Mitsubishi Part Number: 37560-07800
Nozzle Code: DL160T2910NP47E (This follows the common Denso nozzle numbering standard, which Mitsubishi frequently uses).
Specification Breakdown (DL160T2910NP47E)
DL: Nozzle series (Pintle type, Hole nozzle).
160: Body diameter (approx. 16mm).
T: Tip protrusion (Long tip / Top-feed type).
29: Spray angle (29 degrees).
10: Nozzle hole diameter (approx. 0.10 mm? *Note: Usually this refers to the number of holes, but in older codes it can relate to flow. For this specific engine, it indicates a specific flow rate/hole size combination for the 6D22 engine.*)
NP: Nozzle Pintle (Often indicates the holder series).
47: Holder series code (relates to the fitting dimensions).
E: Design revision/engineering standard.
Common Applications
This specific nozzle is most frequently associated with:
Mitsubishi 6D22 (Used in heavy trucks like the Fuso FP/FP, and construction machinery).
Mitsubishi 6D24 (Used in later model Fuso trucks and industrial equipment).
Mitsubishi 6D40 (Used in larger marine and industrial applications).
Physical Verification
When inspecting the physical nozzle:
It should have a long cap nut (long retainer) to hold it into the injector body.
It is a thimble-type (or pintle) nozzle, meaning the needle valve protrudes slightly out of the tip (visible if you look into the spray holes).
The tip is longer than standard "hole-type" nozzles to position the spray deeper into the pre-combustion chamber (if it's an IDI engine) or deeper into the piston bowl.
Important: Always verify the nozzle against the old part. While the cross-reference 37560-07800 = DL160T2910NP47E is standard, there are variations in calibration (pop pressure) depending on whether the engine is turbocharged or naturally aspirated.
