Bosch original 0414701057 0 414 701 057 Fuel Injector Unit Pump for DC11 DC16 Truck Engine Replacement for OEM 0414701019 0414701030 0986441101 original new injector

Engineered specifically for the Scania D12 platform, the BOSCH 0414701057 Unit Injector delivers a precise, engine-matched fuel delivery solution for demanding commercial and industrial applications. This PDE/UIS unit injector is purpose-built to serve DC11, DC12, and DC16 engine families, including variants such as DC11.03, DC11.04, DC12.02, DC12.05, DC12.10, DC12.15, and DC16.02, ensuring correct fuel metering geometry and injection timing across the entire operating range of Scania 114, 124, and 164 Series vehicles.

Built to OEM-level fuel metering accuracy, this injector applies high-pressure injection technology and an optimized spray pattern to promote superior atomization, better fuel economy, and reduced exhaust emissions. The design supports enhanced engine power output, stable operation under heavy loads, improved cold start performance, and lower combustion noise. Cross-referenced to 0414701008, 0986441108, 0986441008, Scania 1409193, 1455861, 1497386, 1529751, 5237152, 0574369, 0574382, and Lucas LDFC0125, it offers reliable interchangeability for fleet and workshop procurement.

Suitable for heavy duty trucks, logistics fleets, generator sets, marine auxiliary engines, and mining equipment, this component ensures long service life and reduced fuel consumption. For optimal reliability, use ultra-clean diesel fuel, replace filters on schedule, prevent water contamination, and perform periodic injector testing. Fault diagnosis is supported through Bosch EPS test bench testing, return flow analysis, nozzle spray pattern inspection, ECU fault code analysis, cylinder balance testing, and fuel pressure testing.
