BOSCH 0445110864 Common Rail Injector for Quanchai QC490 / N
not publicly disclosed by Quanchai - verify by engine build plate F00VC01365 (Bosch F00VC01365 solenoid, CRI2 series) DLLA150P2599 (P/N 0433172599) 1600 bar peak rail pressure Product Overview
BOSCH 0445110864 is a complete CRI2-series solenoid common rail injector assembly engineered for the Quanchai QC490Q / N490Q 2.5-2.8L small diesel platform (inline-4) used in Chinese light commercial vehicles, gensets, forklifts, small tractors, and small machinery. The F00VC01365 solenoid control valve (Bosch F00VC01xxx CRI2 series) meters fuel flow via pulsed ground signals from the ECU at 1-3 ms dwell time per injection event, supporting a 1600 bar peak rail pressure with stable pilot and main injection sequencing for Euro 3 emissions compliance. The DLLA150P2599 multi-hole nozzle (internal Bosch P/N 0433172599) atomizes fuel via precision-drilled orifices for clean combustion. Shares the F00VC01365 control-valve group with sister SKUs 0445110863 and 0445110865 - but each carries a unique IMA calibration code stamped on the solenoid body, so they are NOT fully interchangeable without ECU re-coding via Quanchai service tool. NOTE: earlier fuelpartsdb data wrongly listed this SKU as 'Weichai WD615 / WP10 / WP12' - CORRECTED 2026-07-15 to Quanchai QC490Q per amazon + turbotech cross-references. Weichai WD615/WP10/WP12 use different 0445120-series injectors (e.g. 0445120129, 0445120214, 0445120244, 0445120373).
Always verify the Bosch PN stamping on the solenoid connector cap and the engine build plate BEFORE ordering. This SKU is for QUANCHAI QC490Q / N490Q small commercial diesel family (2.5-2.8L), NOT Weichai WD615/WP10/WP12 heavy-duty (which use different 0445120-series injectors). Each 0445110864 carries a unique IMA calibration code - after installation, use Quanchai service tool or compatible aftermarket scanner to code the ECU.

Frequently Asked Questions
What vehicles does BOSCH 0445110864 fit?
The 0445110864 is for Quanchai (Anhui Quanchai Engine Co., Ltd) QC490Q / N490Q small diesel family (2.5-2.8L inline-4) used in Chinese light commercial vehicles, gensets, forklifts, small tractors, and small machinery. Earlier fuelpartsdb data wrongly listed this SKU for Weichai WD615/WP10/WP12 - that has been CORRECTED. Weichai WD615/WP10/WP12 use different 0445120-series injectors (e.g. 0445120129, 0445120214, 0445120244, 0445120373). Always verify by the Bosch PN stamping on the solenoid connector cap.
Is 0445110864 the same as 0445120129 / 0445120214 / 0445120244?
NO - 0445110864 is a Quanchai 2.5-2.8L injector. The 0445120129 / 0445120214 / 0445120244 / 0445120373 are Weichai WD615/WP10/WP12 heavy-duty 6-cylinder injectors (CRIN2 piezo platform with 0445 120 *** series). Different control valve, different nozzle, different rail pressure range, different ECU protocol.
What control valve and nozzle are on the BOSCH 0445110864?
The 0445110864 is fitted with the Bosch F00VC01365 solenoid control valve (F00VC013xx series, CRI2 platform) and the stamped nozzle DLLA150P2599 (internal Bosch P/N 0433172599). Operating at 1600 bar peak rail pressure for Euro 3 emissions compliance. Source: amazon B0CQGGJ5L7 + turbotech.in (tier B).
What is the correct installation torque and procedure?
Three torque locations: (1) High-pressure fuel line banjo bolt (rail side): 22-25 N·m with a dedicated 14 mm or 17 mm flare nut wrench; (2) Injector hold-down bolt: 18 N·m + 60° angle (Bosch CRIN standard); (3) Feed tube union nut: 1.5 N·m (13 in·lb). Use NEW copper sealing washers + new O-rings.
Does the 0445110864 require IMA coding after installation?
Yes. The 0445110864 is a complete solenoid common rail injector with cylinder-specific IMA values stored in the engine ECU. After installation, use the Quanchai service tool or compatible aftermarket scanner (limited aftermarket support) to code the injectors IMA values. Common mistakes: (a) installing without coding, resulting in cylinder imbalance; (b) using wrong IMA value.
What warranty terms apply?
Standard aftermarket warranty is 12 months from date of purchase, covering manufacturing defects only. Return conditions: manufacturing defect confirmed by bench test; incorrect fitment confirmed before installation; physical damage in shipping - photograph before installation.
What is the most common ordering mistake for the 0445110864?
Three frequent mistakes: (1) Confusing with Weichai WD615 injectors (0445120-series) - different family, NOT compatible. (2) Confusing 0445110864 with sister 0445110863 / 0445110865 - same F00VC01365 valve group but different IMA range; verify by stamping. (3) Confusing with Quanchai QC290Q / N290Q (smaller 1.5L engine) - different nozzle/valve, NOT 0445110864.
