0445120293
Sister SKU - same F00RJ02806 control valve and DLLA150P1827+ nozzle, NOT interchangeable (different IMA calibration)
BOSCH · OE Code A60001112100A38 · Engine Bosch Common Rail (high-pressure solenoid)
The BOSCH 0445120164 is a complete high-pressure solenoid common rail injector assembly engineered for the Yuchai YC6JA / YC6J heavy-duty 6-cylinder diesel platform (6.87-6.9 L displacement, 132-191 kW / 180-260 hp). The F00RJ02806 solenoid control valve meters pilot and main injection via a 1600 bar peak rail pressure, with stable pilot + main injection sequencing for Euro III/Euro V compliance. Designed for medium cargo trucks, dump trucks, road buses (8.5-10.5 m), public buses (8-11 m) and school buses (9-10 m), including the Golden Dragon XML6102J / XML6122J series and the King Long XMQ6106B / XMQ6998 series. Shares the F00RJ02806 control-valve group with sister SKU 0445120293 (same nozzle, same valve, distinct IMA calibration) but is NOT interchangeable - each carries a unique IMA calibration code stamped on the solenoid body. Bosch OE reference part is 0 433 172 115 (DLLA150P1827 stamping); Yuchai OE reference is A60001112100A38; Bosch exchange reference is 0986AD1040.
Always verify the OE reference stamped on your existing injector body and the engine build plate (e.g. YC6JA-30 / YC6JA-50) before ordering. 0445120164 and 0445120293 share the same F00RJ02806 control valve and DLLA150P1827 nozzle group but are NOT interchangeable - they carry distinct IMA calibration values.
