The injector as one of the most complex parts of a diesel engine is required to withstand the pressures and temperatures inside the cylinder to produce an accurate dose of a fine fuel mist to ensure a thorough burn in the cylinder. With extremely small tolerances within injectors, 1 to 3 microns, and very high fuel pressures, issues can arise such as fuel contamination causing wear, or coking of external surfaces from incomplete burn. This clogging can affect the diesel fuel delivery, resulting in increased fuel consumption and a noticeable loss of power. As a key component Perkins injectors are designed specifically for your engine with precision drilled nozzle holes, needle to body gap, and needle design for positive seating and exact fuel delivery to deliver the right fuel flow giving you best power, performance and fuel consumption from your engine.
Application:
Fuel Injector 2645K025 LJBB04801A is designed for Perkins 1100 series diesel engines, including 1103A-33T, 1104D-44T, and 1104D-44TA models. These engines are widely used in agricultural tractors, construction machinery, and generator sets, where precise fuel atomization is essential for combustion efficiency and emissions control.
Technical specifications:
The injector features a multi-hole nozzle and stainless steel needle valve for high-pressure diesel spray. It supports mechanical fuel systems and is calibrated for direct-injection configurations. Compatible with RJ, RS, and RT engine builds.
Material & performance features: The injector body is made from corrosion-resistant alloy steel with precision machining for durability. Internal components are engineered to withstand high thermal stress and mechanical vibration, ensuring consistent performance under continuous operation.
