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.
Technical specifications"
The nozzle features a high-pressure multi-hole design for optimized
spray pattern and combustion. It supports mechanical fuel systems
and is calibrated for direct-injection configurations. Compatible
with L131PBA type injectors used in 1100 series engines.
Material & performance features:
The nozzle body is manufactured from corrosion-resistant alloy
steel with precision machining for durability. Internal components
are designed to withstand high thermal stress and vibration,
ensuring consistent performance under continuous operation.
