Bosch original Diesel Unit Injector Fuel Injector for D12 Diesel Engine FH12 FM12 NH12, Replacement for OEM 0414702025, Compatible with Excavator and Injector Truck Auto Parts original new injector

Engineered for the demanding world of heavy-duty diesel power, the BOSCH 0414702025 Electronic Unit Injector (EUI/UIS) is an original, brand-new fuel injection component manufactured by Robert Bosch GmbH to OEM quality standards. Designed for Volvo Penta D12D engines and the TAD1240/TAD1241/TAD1242 engine family, it is widely referenced under Volvo Penta OE numbers 21160093 and 3801293, making it a trusted replacement across marine, industrial, and power generation platforms.

Built on Bosch UIS/EUI technology, the injector combines mechanical high-pressure generation with electronic injection control. A camshaft-driven plunger builds fuel pressure, while the ECU-activated solenoid valve precisely times needle valve opening, delivering finely atomized fuel into the combustion chamber. The result is precise injection timing, superior fuel atomization, reduced fuel consumption, lower exhaust emissions, improved engine power, enhanced torque response, and stable combustion under varying load conditions.

Industrial-grade construction with hardened internal components, corrosion-resistant materials, and precision manufacturing ensures long service life in harsh operating environments. The 0414702025 serves marine propulsion and auxiliary engines, diesel generator sets, emergency power units, construction and mining equipment, agricultural machinery, and power generation plants. For dependable performance, Bosch recommends ultra-clean diesel fuel, scheduled filter replacement, contamination-free installation with new sealing components, and post-installation ECU diagnostics to verify injection balance.
