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 131406500 is designed for Perkins 400 series diesel engines, including 403D-15 and 404D-22 models. These compact engines are widely used in generator sets, agricultural machinery, and industrial equipment, where precise fuel delivery is essential for combustion efficiency and emissions control.

Technical specifications:

The injector features a high-pressure nozzle with calibrated spray pattern for direct-injection diesel systems. It supports mechanical fuel configurations and is optimized for small displacement engines in the 400 series.

Material & performance features:

Manufactured from corrosion-resistant alloy steel, the injector is precision-machined to ensure consistent fuel atomization. Internal components are engineered for durability under high thermal and mechanical stress, maintaining stable performance in continuous operation.
