WESPC Filter 2645K613 Injector Nozzle Diesel Component For Perkins 1103 1104 Engine

The injector nozzle which sits in the injector body 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 and is one of the most complex parts of a diesel engine. With extremely small tolerances within injectors and very high fuel pressures, issues can arise such as fuel contamination causing wear, or coking of external surfaces from an incomplete burn. This clogging can affect the diesel fuel delivery, resulting in a noticeable loss of power and increased fuel consumption. 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 fuel consumption, power and performance from your engine.

Application:

Injector Nozzle 2645K613 is engineered for Perkins 1103 and 1104 series diesel engines, including 1103A-33T, 1104C-44T, and 1104D-44TA models. These engines are widely used in agricultural tractors, generator sets, and construction machinery, where precise fuel atomization is essential for combustion efficiency and emissions control.
