As a precision-engineered original OEM component built for Caterpillar’s 3412 engine platform, the 20R-4147 diesel fuel injector meets strict factory specifications for industrial and heavy-duty use across global markets. Fully compatible with CAT 3412, 3412B and 3412C engines, it cross-references part numbers 10R-7222, 331-8770 and 0R-4171 to simplify replacement parts sourcing for international buyers.
Manufactured from high-grade alloy steel with excellent wear and corrosion resistance, this injector supports continuous heavy-load operation with stable fuel delivery performance. Operating at 1200–1600 bar with a 150°–160° spray angle, it atomizes diesel into fine droplets to enable complete combustion, reduce smoke and emissions, improve fuel efficiency and maximize torque output. It works with engine camshaft or ECU systems to adjust injection timing according to load and RPM variations, and is compatible with standard industrial diesel and biodiesel blends.
Engineered for industrial-grade scenarios, the 20R-4147 injector serves mining, construction, marine, power generation and large-scale agricultural sectors, covering equipment ranging from excavators and bulldozers to marine vessels, diesel generators and farm machinery. It comes with a 12-month industrial warranty, follows official Caterpillar 35–40 Nm installation torque specs, and supports recommended routine maintenance practices to extend overall service life.
