Caterpillar original 20R-8062 Fuel Injector GP for C9 Engine Replacement for OEM 20R-8063, for heavy duty diesel engine application, 387-9436, 10R-4844 for Excavator Truck Parts original new injector

Engineered for the Caterpillar C9 diesel engine platform, the 20R-8062 Fuel Injector is a precision-built, electronically controlled high-pressure injection component designed for demanding industrial duty cycles. Serving the 8.8-liter inline six-cylinder turbocharged C9 and C9 ACERT engines, it delivers accurately metered fuel with optimized spray atomization for stable combustion across the full load range. As the final, most critical element of the Caterpillar electronic fuel injection system, it directly influences power output, fuel economy, emission control, and cold-start performance.

Under ECM command, the injector's electronic solenoid lifts the needle valve at precisely calculated timing, releasing high-pressure diesel through precision-calibrated nozzle holes for fine atomization and controlled combustion. This delivers improved combustion efficiency, reduced fuel consumption, increased horsepower, lower exhaust emissions and particulate generation, sharper throttle response, stable idle, and easier cold starting. Advanced machining, precision nozzle calibration, high-strength alloy materials, and stringent quality control ensure OEM-equivalent performance and long service life under extreme operating conditions.

The 20R-8062 serves a broad global equipment base, fitting CAT 330D and 336D excavators, 966H and 972H wheel loaders, 140M motor graders, generator sets, marine propulsion systems, and industrial power units across construction, mining, marine, and power generation sectors. Cross-referenced as 20R8062, 326-1641, and 3261641, it simplifies sourcing for distributors, repair workshops, fleet operators, and engine rebuilders. Compatibility should always be confirmed by engine serial number (ESN) and equipment serial number (PIN).
