Ca-terpillar 3316 Diesel Fuel Injector
OEM Replacement Fuel Injector for Ca-terpillar 3316 Engine | Mechanical Unit Injector MUI Heavy-Duty Cat Injector
Our premium aftermarket Ca-terpillar 3316 fuel injector is engineered as a direct OEM drop-in replacement for Cat 3316 heavy-duty diesel engines. Built with high-strength alloy steel and precision ground internal components, this mechanical unit injector delivers accurate fuel metering, stable high-pressure atomization, and consistent power output for construction machinery, industrial generators, marine engines and heavy trucks. Fully bench-tested before shipment, it minimizes downtime, cuts fuel consumption and extends engine service life for all your Cat equipment.
The Ca-terpillar 3316 unit injector is the core fuel delivery component of the Cat 3316 mechanical diesel engine system. Adopting classic MUI (Mechanical Unit Injector) structure, it integrates plunger, high-pressure chamber, needle valve and control valve into one compact assembly, driven directly by the engine camshaft rocker arm to generate injection pressure without external high-pressure fuel lines.
This injector precisely controls fuel injection timing, volume and spray pattern per Cat OEM standards. It sprays fine atomized diesel into combustion chambers to realize full fuel-air mixing, drastically improving combustion efficiency, lowering black smoke, reducing NOx and particulate emissions, and restoring original engine horsepower and torque.
Worn, leaking or clogged injectors will trigger rough idling, power loss, excessive fuel burn, engine knocking and accelerated cylinder wear. Our replacement 3316 injectors solve all these failure points with upgraded wear-resistant coatings and brand-new sealing kits.
