Details & Benefits

Product Name

c-aterpillar Fuel Injector Nozzle

Part Number (General Number)

0R-1745

Ultra-Fine Atomization

5-hole precision-drilled orifice with 142μm diameter ensures uniform and fine fuel droplets, optimizing fuel-air mixing, improving combustion efficiency by up to 29%, and reducing fuel consumption effectively for heavy-duty 3304/3406/3412 series engines[3].

High-Pressure Durability

Engineered to withstand 11.0 MPa operating pressure, with heat-treated alloy steel construction (HRC57-59) that resists deformation and leakage under high-pressure conditions, ensuring stable performance in long-term heavy-load operations for multi-series c-aterpillar engines.

Anti-Clogging & Anti-Wear

Smooth orifice surface and wear-resistant coating prevent dust, carbon deposits, and impurities from clogging, extending the nozzle's service life in dusty and harsh working environments common in construction, mining, and industrial applic-ations, suitable for the diverse operating conditions of its compatible engines[3].

OEM Compatibility

Direct-fit design strictly matches c-aterpillar OEM specific-ations, requiring no modific-ations during installation, ensuring perfect integration with the injector and fuel system for 3304/3306/3406B/3408/3412 series engines[2][3].
