Bosch original Common Rail Fuel Injector 1920420 1487472 for D12 Engine, Replacement for OEM 1942702, Cross Reference 1766549 for Excavator original new injector

Engineered for the Volvo D12 heavy-duty diesel engine platform, the BOSCH 1920420 fuel injector is a precision-built common rail injection component manufactured to strict OEM specifications. Serving as a direct OEM replacement, it interchanges with Volvo OE numbers 20524606, 20524607, 20524608, 8113941, and 8112515, plus cross reference numbers 20440388, 20459183, 20459204, and 8112509, giving distributors and fleet buyers a single, reliable sourcing option for the entire D12 series.

Inside the injector, a high-precision control valve meters fuel quantity while the calibrated needle lifts to deliver finely atomized diesel into the combustion chamber, then closes immediately after each injection cycle. Precision machined and wear resistant internal components, multi-hole nozzle technology, corrosion resistant materials, and thermal resistant construction ensure stable high-pressure operation in demanding conditions. The result is optimized fuel atomization, improved combustion efficiency, lower fuel consumption, reduced particulate emissions, increased power output, reduced engine noise, and longer engine service life.

The 1920420 injector fits Volvo D12A, D12B, D12C, D12D, D12E, TD122, marine, and industrial D12 engines, covering Volvo FH12, FM12, and NH12 trucks, B12 buses, VT and VHD series, plus excavators, wheel loaders, articulated haulers, industrial engines, and generator sets. Supplied at OEM standard quality in neutral packaging or custom branding, backed by a 6-12 month warranty and flexible air, sea, or express shipping, it supports high-volume fleet orders across truck, bus, construction, marine, and industrial markets worldwide.
