Product Introduction
In commercial diesel engines operating under sustained high load – such as heavy-duty trucks, agricultural equipment, and marine auxiliary power units – the fuel spray must penetrate the dense air charge to reach the outer regions of the piston bowl where combustion is most complete. The Liwei V0605P144 is a precision-ground nozzle engineered with a 6-hole configuration and 0.205 mm diameter orifices – a geometry that provides a static flow of 1,020 cc/min at 100 bar, delivering the fuel volumes required for 3.0L to 5.0L commercial diesel engines with power outputs exceeding 250 PS. The defining characteristic of the V0605P144 is its narrow 144° spray angle, which provides 18% greater spray penetration than standard 150° nozzles, ensuring the fuel reaches the bowl's outer radius even at the high swirl ratios typical of commercial diesel platforms. The reduced number of holes (6 vs. the more common 7 or 8) provides higher fuel velocity through each orifice, delivering the fuel charge to the combustion zone with minimal dispersion, improving combustion efficiency in high-load applications.
█ Application Coverage – High-Output Commercial Diesel Platforms
The V0605P144 is designed to replace nozzles in the following common rail injector families:
Bosch CRI 1.0 / 2.0 – Injectors with 6-hole × 0.205 mm geometry, including 0445110019, 0445110075, 0445110092, and similar part numbers
Denso G2 – Injectors with 6-hole × 0.205 mm configuration in high-output commercial applications
Vehicle Applications – Toyota 1KD-FTV (3.0 D-4D high-output), Isuzu 4JJ1 (3.0L), Mitsubishi 4M41 (3.2L), Nissan YD25 (2.5L commercial), MAN D08, Scania 5-cylinder engines, and heavy-duty 4×4 platforms
The nozzle is a direct replacement for Bosch part numbers 0445110019, 0445110075, 0445110076, and Denso nozzles with the 6 × 0.205 mm configuration. It is supplied as a bare nozzle – the needle and nozzle must be lapped together during assembly.

◆ Construction Details – High-Penetration Optimisation
→ 6-Hole × 0.205 mm Geometry: Fewer, larger orifices provide 18% greater spray penetration, delivering fuel effectively to the bowl's outer radius in high-swirl commercial engines.
→ 144° Narrow Spray Angle: Resists swirl-induced deflection, ensuring the fuel plume remains on trajectory in high-swirl commercial engines.
→ M42 High-Speed Steel: Manufactured from cobalt-containing steel, providing hot hardness up to 650°C for sustained high-load operation.
→ DLC Coating: The needle guide receives a 1.5 µm diamond-like carbon coating, reducing friction and extending service life in high-soot environments.
→ Superfinished Guide Surface: The guide is superfinished to Ra ≤ 0.08 µm, ensuring smooth needle movement.
