Yanmar Series 1100F Injector, with top-mounted fuel inlet, M12x1.5 thread, and four/five-hole orifice nozzle, suitable for the 1100FE engines produced in China

The 1100F fuel injector is specifically designed for the direct injection system of the 1100FE single-cylinder diesel engine. It features a top fuel inlet with an M12x1.5 thread and a hole-type nozzle operating at 21 MPa. Available in both 4-hole and 5-hole configurations, the injector offers nozzle diameters of 0.26 mm and 0.23 mm, supporting flow rates between 1.20 and 1.30 L/min to meet different atomization requirements.

At a rated speed of 3000 RPM, the injector delivers precise fuel injection to ensure complete combustion. Working in tandem with the solenoid-controlled injection pump, it helps the engine achieve stable power output while reducing fuel consumption. With fast injection response and consistent spray quality, this injector supports reliable engine performance under varying operational loads and ambient conditions. It is well-suited for agricultural engines, portable generator sets, and compact industrial diesel applications.
