The Perkins 20R-8061 is a precision-engineered high-pressure common rail diesel fuel injector designed specifically for Perkins C9, C9.3, and C9 ACERT engine platforms. Manufactured using hardened alloy steel, precision-ground internal components, and advanced nozzle technology, this injector delivers accurate fuel metering, stable idle operation, and fast response time across demanding industrial environments. It is engineered to meet OEM manufacturing standards, providing improved fuel economy, reduced exhaust emissions, and reliable cold-start performance.

Compatible cross reference numbers include 287-8061, 10R-8020, 147-2412, and 268-8061, allowing direct replacement across a wide range of Perkins C9 engine variants. The injector is widely used in construction equipment such as excavators and wheel loaders, mining machinery, heavy-duty trucks including CT660 and CT680 models, power generation systems, and marine propulsion engines. Its wear-resistant internal components, heat-treated body, and corrosion-resistant surface ensure long service life under extreme temperature conditions and heavy load operation.

The high-pressure injection system works by drawing fuel from the transfer pump, increasing pressure through the common rail, and delivering precisely atomized fuel into the combustion chamber based on electronic ECU signals. This process results in better combustion, increased engine power, reduced black smoke, and overall lower fuel consumption. To ensure optimal performance, installers should clean the injector bore, replace sealing washers and O-rings, inspect fuel lines and injector harness, and verify injection timing after installation.
