Reliable fuel delivery is the foundation of every high-output diesel engine, and the Caterpillar 20R-0850 Fuel Injector is engineered to deliver exactly that. This OEM-quality diesel injector, also referenced as 20R0850 with OE numbers 392-0213 and 3920213, is designed for CAT 3500 Series engines, including the 3512B, 3516B, 3508B, 3512C, and 3520. Cross references 1476229, 1504454, 2290191, 2501313, 3602392, and 3619355 simplify sourcing across Caterpillar parts channels and global supplier networks.
Precision machined from hardened alloy steel with anti-wear coatings, the injector converts pressurized diesel into a finely atomized spray directed into the combustion chamber. Electronic unit injection timing controls precise injection points, the needle valve lifts under fuel pressure, and high-precision nozzle holes produce a uniform mist for even air-fuel mixing. Optimized combustion delivers stable power output, improved fuel economy, reduced smoke, and lower emissions, even under extended heavy-load operation.
The 20R-0850 serves industrial power generation (prime and standby), marine propulsion, mining truck power units, oil and gas pump and compressor drives, and heavy construction machinery. To maximize service life, verify injector bore condition before installation, replace OEM seals, apply proper torque settings, and perform post-installation testing. Regular fuel filter replacement and high fuel quality are critical to preventing premature wear, while black smoke, white smoke, or power loss can indicate worn nozzles, timing delay, or seal leakage.
