Product Introduction
In modern diesel engine design, the clearance between the injector nozzle and the piston bowl wall is a critical dimension – if the spray penetrates too far, fuel impinges on the cylinder wall; if it penetrates insufficiently, the air in the bowl's outer radius remains unused, increasing particulate emissions. The Liwei V0208P152 is a precision-ground nozzle engineered with a 152° spray angle – a geometry that provides the optimal balance between spray dispersion and penetration for engines with intermediate-depth piston bowls, delivering the fuel cloud to the bowl's outer regions while maintaining sufficient clearance from the cylinder wall. Featuring a 7-hole configuration with 0.180 mm diameter orifices, the V0208P152 delivers a static flow of 790 cc/min at 100 bar, matching the fuel requirements of 2.0L to 2.2L diesel engines in Euro 5 and Euro 6 emissions-compliant applications. The spray angle provides 6% shorter penetration than standard 150° nozzles, reducing wall-wetting risk while maintaining adequate air utilisation.
█ Application Coverage – 2.0L–2.2L Euro 5/6 Diesel Platforms
The V0208P152 is designed to replace nozzles in the following common rail injector families:
Bosch CRI 2.0 / 2.2 – Injectors with 7-hole × 0.180 mm geometry, including 0445110414, 0445110415, 0445110423, and similar part numbers
Denso G2 / G3 – Injectors with 7-hole × 0.180 mm configuration in Euro 5/6 applications
Vehicle Applications – Peugeot/Citroën 2.0 HDi (DW10), Ford 2.0 TDCi, Fiat 1.9/2.0 Multijet, Opel 1.7/2.0 CDTi, Toyota 2.0 D-4D, and similar Euro 5/6 diesel platforms with intermediate-depth piston bowls
The nozzle is a direct replacement for Bosch part numbers 0445110414, 0445110415, 0445110423, and Denso nozzles with the 7 × 0.180 mm configuration. It is supplied as a bare nozzle – the needle and nozzle must be lapped together during assembly.

◆ Construction Details – Balanced-Penetration Optimisation
→ 152° Spray Angle: Provides a 6% reduction in spray penetration compared to standard 150° nozzles, reducing wall-wetting risk while maintaining adequate air utilisation in intermediate-depth piston bowls.
→ 7-Hole × 0.180 mm Geometry: Smaller orifice diameter provides fine atomisation (SMD ≈ 20 µm) for Euro 5/6 emission standards, balancing flow and atomisation.
→ M42 High-Speed Steel: Manufactured from cobalt-containing steel, providing hot hardness up to 650°C.
→ DLC Coating: The needle guide receives a 1.2 µm diamond-like carbon coating, reducing friction and extending service life in high-soot EGR environments.
→ Superfinished Guide Surface: The guide is superfinished to Ra ≤ 0.08 µm, ensuring smooth needle movement.
