BOSCH 0445120164 Common Rail Injector for Yuchai YC6JA
Same F00RJ02703 control valve, different IMA calibration (YC6JA, 6.5L bus platform)
BOSCH · OE Code J0100-1112100-A38 · Engine Common Rail
The BOSCH 0445120165 is a complete injector assembly engineered for the Yuchai YC6J EU4 heavy-duty platform. The F00RJ02703 solenoid control valve meters fuel flow via current-driven pilot injection, supporting a 1600 bar peak rail pressure with stable multi-pulse combustion across 4 main injections per cycle. The DLLA150P2123 nozzle (8 holes, 0.145mm hole diameter, 150deg spray angle) atomizes fuel into the 105x125 mm bore of the YC6J's 6.494L inline-6 cylinder block. Output range: 118-199 kW (160-270 HP), peak torque 950 N.m at 1200-1700 rpm. Common applications include 8.5-11m city buses (Yutong, Higer, Kinglong), 9-10m school buses, and 6-12 tonne medium-duty cargo trucks. The YC6J family has been in continuous production for over 20 years with a B10 service life of 700,000 km. Shares the F00RJ02703 control-valve group with 30+ sister SKUs (including 0445120164, 0445120156, 0445120166, 0445120170, 0445120182) but is NOT interchangeable - each carries a unique IMA calibration code stamped on the solenoid body.
Verify the IMA calibration code on the solenoid body and the J0100-1112100-A38 OE stamp before installation. 0445120165 shares the F00RJ02703 control-valve group with 30+ sister SKUs but is NOT interchangeable with 0445120164 (YC6JA, 6.5L) - the IMA calibration differs.
