Engine fuel injector nozzles are precision components that spray fuel into the combustion chamber in a fine mist for efficient burning. Fuel systems deliver, regulate, and optimize fuel flow from the tank to the engine. Together, they ensure proper fuel-air mixture, enhancing performance and reducing emissions.

Size: Typically ranges from 0.1 mm to 0.5 mm orifice diameter.

Grade: High-precision components, often meeting ISO 9001 or SAE J967 standards.

Viscosity: Compatible with fuels ranging from 1.3 to 4.1 cSt at 40°C.

Buoyancy: Negligible due to small size and dense materials.

Material: Stainless steel (AISI 303, 304), hardened tool steel, or ceramic coatings for wear resistance.

Pressure Range: Operates between 100 to 300 MPa (common for diesel injectors).

Spray Angle: Configurable from 60° to 150° depending on application.

Flow Rate: Varies from 200 to 1000 cc/min at rated pressure.

Sealing: Viton or PTFE seals for fuel compatibility.

Temperature Range: -40°C to +140°C operational limits.
