Product Introduction
In common rail diesel systems, the nozzle's total orifice area determines the maximum fuel delivery rate, which directly influences the engine's power output and torque characteristics. The Liwei M0048 is a precision-ground nozzle engineered with an 8-hole configuration and 0.210 mm diameter orifices – the largest orifice diameter in the Liwei range – delivering a static flow of 1,100 cc/min at 100 bar, a specification that positions it as a high-flow solution for engines with power outputs exceeding 300 PS. This nozzle features a 148° spray angle, optimised for the deep-bowl combustion chambers of 3.0L to 5.0L diesel engines used in light commercial vehicles, SUVs, and performance diesel applications. The defining metric of the M0048 is its flow consistency under continuous high-load operation – a maximum deviation of ±2.0% from nominal delivery over 5,000 operating hours, a tolerance that ensures stable power output in towing, off-road, and high-speed applications. Its oversized orifice configuration reduces injection duration for a given fuel quantity, allowing earlier injection timing and improved fuel economy at high load – a key differentiator for commercial operators and performance-oriented diesel owners.
█ Application Coverage – High-Flow Common Rail Platforms
The M0048 is designed to replace high-flow nozzles in the following common rail injector families:
Bosch CRI 2.0 / 2.2 – Injectors with 8-hole × 0.210 mm or larger nozzle geometry, including 0445110092, 0445110093, and similar part numbers
Denso G2 / G3 – High-flow injectors with 8-hole configuration in commercial and performance applications
Vehicle Applications – Compatible with Audi 2.5 TDI V6, BMW M57 3.0L, Mercedes OM613/OM648, Toyota 3.0 D-4D, Isuzu 3.0/4.0L commercial diesel platforms, and performance-tuned common rail engines
The nozzle is a direct replacement for Bosch part numbers 0445110092, 0445110093, and Denso nozzles with the 8 × 0.210 mm configuration. It is supplied as a bare nozzle – the needle and nozzle must be lapped together during assembly to achieve the 4–6 micron clearance.

◆ Construction Details – The High-Flow Optimisation
→ 0.210 mm Orifice Diameter: The largest orifice in the Liwei family, providing 26% greater flow area than the 7 × 0.190 mm configuration.
→ 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.
→ Superfinished Guide Surface: The guide is superfinished to Ra ≤ 0.08 µm, ensuring smooth needle movement.
→ Large Seat Diameter: The 4.2 mm seat diameter provides a generous sealing surface, distributing the needle impact force and reducing seat erosion in high-flow applications.
