The c-aterpillar 10R-1279 fuel injector is a premium genuine OEM replacement component meticulously engineered for the c-at 3512B series 12-cylinder V-type diesel engine, a powerhouse widely deployed in heavy industrial manufacturing, marine propulsion, stationary power generation, oilfield exploitation and large-scale infrastructure projects. Manufactured in full accordance with c-aterpillar’s stringent original design standards and quality control protocols, this injector incorporates advanced MEUI (Mechanically Actuated Electronically Controlled Unit Injector) technology to deliver pinpoint fuel delivery, ultra-refined atomization and consistent injection timing. Built with a rugged, heavy-duty structure, it resists high-pressure fatigue, diesel fuel corrosion, abrasive contaminants and extreme operating conditions, guaranteeing long-lasting durability and stable performance. Fitting the authentic 10R-1279 injector effectively restores original engine power, optimizes fuel efficiency, reduces harmful exhaust emissions and reduces equipment downtime, making it an indispensable spare part for routine maintenance, engine overhaul and fault repair of c-at 3512B power units.

1. Core Basic Specific-ations Table

Parameter Item Specific Value
