Product Introduction
In commercial diesel engines with high-swirl combustion systems, the fuel spray must penetrate the dense air charge to reach the outer regions of the piston bowl where combustion is most efficient. The Liwei V0600P142 is a precision-ground nozzle engineered with a 6-hole configuration and 0.200 mm diameter orifices – fewer, larger holes that provide deeper spray penetration and higher fuel velocity than multi-hole designs. This nozzle features a 142° spray angle, a narrow angle that directs the fuel plume into the bowl's outer radius, resisting swirl-induced deflection. The reduced number of holes (6 vs. the more common 7 or 8) simplifies the spray pattern and provides 15% greater penetration than a comparable 8 × 0.195 mm nozzle at identical rail pressure, ensuring the fuel reaches the combustion zone even at the high swirl ratios typical of commercial diesel platforms.
█ Application Coverage – Commercial & 4x4 Diesel Platforms
The V0600P142 is designed to replace nozzles in the following common rail injector families:
Bosch CRI 1.0 / 2.0 – Injectors with 6-hole × 0.200 mm geometry, including 0445110019, 0445110075, and similar part numbers
Denso G2 – Injectors with 6-hole × 0.200 mm configuration in commercial applications
Vehicle Applications – Toyota 1KD-FTV (3.0 D-4D), Isuzu 4JJ1 (3.0L), Mitsubishi 4M41 (3.2L), Nissan YD25 (2.5L), commercial 4×4 platforms, and light truck diesel engines
The nozzle is a direct replacement for Bosch part numbers 0445110019, 0445110075, 0445110076, and Denso nozzles with the 6 × 0.200 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 × 0.200 mm Geometry: Larger individual holes provide higher fuel velocity and 15% greater penetration than multi-hole designs, delivering fuel effectively to the bowl's outer radius.
→ 142° 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.
→ 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.
