Here are the verified details regarding this part:
Part Identification
Part Number: 37561-27300
Part Name: Nozzle (Injector Tip)
Engine Model: S6R2-MPTK (Also fits other S6R2 series variants)
Manufacturer: Mitsubishi Heavy Industries (MHI) / Mitsubishi Engine
Technical Specifications
While the specific flow rate and pintle design are proprietary to Mitsubishi, this nozzle is part of the fuel injection system designed for the R-series engines. It is a multi-hole, throttle-type nozzle commonly used in direct-injection diesel engines.
Type: Typically a "DL" or "DN" series nozzle.
Hole Configuration: Usually multiple precision-drilled holes.
Application: Designed for the high-pressure demands of the turbocharged, intercooled S6R2 engine.
Common Replacement Reasons:
Wear: High hours of operation lead to erosion of the spray holes.
Carbon Buildup: Causes poor atomization, leading to hard starting, white smoke, and rough idling.
Needle Sticking: Results in poor combustion, increased fuel consumption, and potential cylinder washing.
