Product Introduction
In Euro 6 emissions-compliant diesel engines, the combustion strategy has shifted toward lower peak temperatures and reduced particulate formation – a requirement that has driven changes in piston bowl geometry and injector nozzle design. The Liwei M0012P154 is a precision-ground nozzle engineered with a wide 154° spray angle – 4° wider than the standard 150° – specifically calibrated for modern shallow-bowl pistons where short spray penetration is essential to prevent fuel impingement on the cylinder walls. This wider angle creates a broader, more dispersed fuel plume that reduces tip penetration, ensuring the fuel cloud remains within the piston bowl boundaries throughout the injection event. With a 7-hole configuration and 0.190 mm diameter orifices, the M0012P154 delivers a static flow of 870 cc/min at 100 bar, a specification that matches the fuel requirements of 2.0L to 2.2L Euro 6 diesel engines used in passenger car and light commercial applications. The defining metric of this nozzle is its reduced wall-wetting tendency – a 20% reduction in fuel impingement compared to standard 150° nozzles, contributing to lower oil dilution and extended DPF regeneration intervals.
█ Application Coverage – Euro 6 Diesel Platforms with Shallow-Bowl Pistons
The M0012P154 is designed to replace nozzles in the following common rail injector families:
Bosch CRI 2.2 / 2.4 – Injectors with 7-hole × 0.190 mm nozzle geometry used in Euro 6 emissions-compliant engines
Denso G3 – Injectors with 7-hole × 0.190 mm configuration in Euro 6 applications
Vehicle Applications – Compatible with Euro 6 variants of Mercedes OM651, BMW N47/N57, VW/Audi 2.0 TDI (EA288), Ford 2.0 EcoBlue, PSA 2.0 BlueHDi, and Volvo D4/D5
The nozzle is a direct replacement for Bosch part numbers 0445110654, 0445110661, and Denso nozzles with the 7 × 0.190 mm configuration used in Euro 6 platforms. It is supplied as a bare nozzle – the needle and nozzle must be lapped together during assembly.

◆ Construction Details – Shallow-Bowl Optimisation
→ 154° Wide Spray Angle: The widest angle in the Liwei range, providing 10% shorter spray penetration for shallow-bowl Euro 6 pistons.
→ M42 High-Speed Steel: Manufactured from cobalt-containing steel, providing hot hardness up to 650°C.
→ DLC Coating: The 1.5 µm diamond-like carbon coating reduces friction and extends service life.
→ Superfinished Guide Surface: The guide is superfinished to Ra ≤ 0.08 µm.
