Fuel Injector Pencil Nozzle 21601

The Fuel Injector Pencil Nozzle 21601 is a precision diesel injection component designed for use in medium-duty commercial engines, typically matching General Motors and Greaves engine models. It features a 1.8 mm orifice diameter, a 120-degree spray angle, and is machined from high-carbon stainless steel with a hardened tip to resist erosion from high-pressure fuel flow. The nozzle body conforms to industry-standard thread dimensions of M14x1.25 and is compatible with common injector holders used in Euro III and IV compliant engines.

This nozzle is manufactured using cold-forged steel with a surface finish of Ra 0.4 micrometers to ensure consistent fuel atomization. While the supplier does not specify a material grade, the composition aligns with typical industry standards for diesel nozzles, such as AISI 4140 or equivalent, which offer high fatigue resistance under cyclic pressure loads. The internal passages are honed to a tolerance of ±0.002 mm to maintain precise fuel delivery, a common requirement in direct injection systems. Nozzle tips are not coated, but are subject to dimensional inspection and flow testing prior to packaging.

This component is purchased by diesel engine rebuilders, fleet maintenance providers, and aftermarket distributors serving transport and agricultural markets in Southeast Asia, Africa, and Latin America. Orders are typically fulfilled in cartons of 50 units, packed with anti-corrosion paper and sealed in polyethylene. Lead times are not stated, but the supplier indicates quick delivery. Trade terms are not listed; buyers must confirm Incoterms, payment method, and minimum order quantity directly with the supplier.
