Product Introduction
In common rail diesel systems, the spray angle is a critical parameter that determines how effectively the fuel cloud interacts with the piston bowl's air motion. An incorrect spray angle results in wall wetting – fuel impinging on the cylinder walls – or over-penetration, where the fuel reaches the piston crown before complete combustion. The Liwei M1001P152 is a precision-ground nozzle engineered with a 152° spray angle – 2° wider than the standard 150° angle used in most 2.0L diesel injectors – optimised for the deeper, re-entrant piston bowls found in Euro 5 and Euro 6 compliant engines. This wider spray angle ensures that the fuel plume follows the contour of the combustion bowl, improving air utilisation and reducing soot formation. With a 7-hole configuration and 0.185 mm diameter orifices, the M1001P152 delivers a static flow of 840 cc/min at 100 bar, a specification that positions it between the 0.190 mm and 0.175 mm nozzles, offering a balance of flow and atomisation for 2.0L to 2.2L diesel engines.
█ Application Coverage – Compatible Injector Platforms
The M1001P152 is designed to replace nozzles in the following common rail injector families:
Bosch CRI 2.0 / 2.2 – Injectors with 7-hole × 0.185 mm nozzle geometry, including 0445110265, 0445110480, and similar part numbers
Denso G2 / G3 – Injectors with 7-hole × 0.185 mm configuration
Vehicle Applications – Compatible with Ford 2.0/2.2 TDCi, PSA 2.0/2.2 HDi, Mercedes OM651, BMW N47 2.0L, and VW/Audi 2.0 TDI applications with Euro 5/6 emissions compliance
The nozzle is a direct replacement for Bosch part numbers 0445110265, 0445110480, 0445110481, and Denso nozzles with the 7 × 0.185 mm configuration. It is supplied as a bare nozzle – the needle and nozzle must be lapped together during assembly.

◆ Construction Details – The Spray Angle Optimisation
→ 152° Spray Angle: The wider spray angle matches the re-entrant bowl geometry of Euro 5/6 pistons, ensuring the fuel plume follows the bowl contour.
→ 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 DLC coating, reducing friction and extending service life.
→ Superfinished Guide Surface: The guide is superfinished to Ra ≤ 0.08 µm.
