Caterpillar C9 Injector 293-4067 / 10R-7223
Hydraulic precision to maximize the efficiency of your construction sites
Fuel injector, part numbers 293-4067 (nine) and 10R-7223 (CAT certified exchange unit), is a high-tech electro-hydraulic component designed for injection systems HEUI (Hydraulic Electronic Unit Injector) of engines Caterpillar C9. Used in particular on production hydraulic excavators CAT 330C, This injector uses engine oil pressure to pressurize the diesel fuel to extreme levels. With a view to sustainable maintenance and increased productivity, This module guarantees micrometric regulation of flow rates, offering maximum breakout force and a drastic reduction in fuel consumption.
HEUI engineering and resistance to severe stresses
Technical transparency is our top priority to preserve the mechanical health of your heavy equipment.
-
Hydraulic Actuation Technology: Uses high-pressure oil to generate a clean injection pulse, independent of engine speed, ensuring high torque even at low engine speeds.
-
Treated Spray Nozzle: Laser-calibrated micro-orifices ensure homogeneous atomization of the diesel fuel, eliminating hot spots in the combustion chamber.
-
Hardened Solenoid Valve: High thermal tolerance electrical winding ensuring instant opening and closing of the injector for perfect dosing.
-
Multi-Element Sealing Segmentation: Equipped with reinforced O-rings (Viton/Fluorocarbon) capable of perfectly isolating the fuel circuit, the oil circuit and the cylinder head.
