Bosch original 0445110631 Common Rail Fuel Injector Replacement for Diesel Engine, Compatible with 4JB1, S350, DP1-9K546-AA, for Truck Use original new injector

Engineered for modern diesel engines with Common Rail Direct Injection (CRDI) technology, the Bosch 0445110631 fuel injector is a precision-built, high-pressure injection component within the proven Bosch 110 Series family. Manufactured from high-strength alloy steel to OEM quality standards under ISO-certified production, it operates at rail pressures of up to 2000 bar while maintaining durability over extended service intervals. This electronic solenoid injector delivers accurate fuel metering and exceptional atomization across commercial trucks, buses, construction machinery, agricultural tractors, generator sets, mining equipment, and marine diesel applications.

Controlled by the engine ECU, the fast-response solenoid valve executes precisely timed, multiple injection events. High-pressure fuel from the common rail atomizes into ultra-fine droplets, maximizing combustion efficiency while reducing fuel consumption, exhaust emissions, and noise. The injector also improves power output and cold-start performance, and supports Euro III, Euro IV, and Euro V emission platforms. Corrosion-resistant construction ensures long service life across turbocharged and intercooled 4-cylinder and 6-cylinder diesel engines.
