Product Introduction
In common rail diesel systems, the nozzle's orifice diameter directly determines the maximum fuel quantity that can be delivered within the injection window – a constraint that becomes critical in large-bore engines where fuel volumes per stroke exceed 250 mm³. The Liwei M1600 P150 is a high-flow nozzle engineered for commercial vehicle and industrial diesel engines requiring delivery rates above 1,000 cc/min at 100 bar, making it suitable for 5.0L to 7.0L displacement engines. This nozzle features an 8-hole configuration with 0.205 mm diameter orifices and a 148° spray angle – a geometry that provides a droplet SMD of approximately 24 µm and delivers a static flow of 1,050 cc/min at 100 bar. The defining metric of the M1600 P150 is its flow stability under high-load conditions – the nozzle maintains its delivery characteristic within ±2.5% of nominal over 6,000 operating hours, a specification that ensures consistent power output in continuous-duty applications such as trucking and generator sets.
█ Application Coverage – Compatible Injector Platforms
The M1600 P150 is designed to replace nozzles in the following common rail injector families:
Bosch CRI 2.0 / 2.2 – Injectors with 8-hole × 0.205 mm nozzle geometry, including 0445110075, 0445110092, and similar part numbers
Denso G2 / G3 – Injectors with 8-hole × 0.205 mm configuration
Vehicle Applications – Compatible with Volvo D5/D6, Mercedes OM613, Audi 2.5 TDI V6, MAN D08, and DAF engines using the above injector families
The nozzle is a direct replacement for Bosch part numbers 0445110076, 0445110093, and Denso nozzles with the 8 × 0.205 mm configuration. It is supplied as a bare nozzle – the needle and nozzle must be lapped together during assembly.

◆ Construction Details – The High-Flow Optimisation
→ M42 High-Speed Steel with 8% Cobalt: Provides hot hardness retention up to 650°C for the higher thermal loads of commercial diesel engines.
→ DLC Coating on Needle Guide: A 1.5 µm diamond-like carbon coating reduces the coefficient of friction to 0.10–0.12 and extends service life in high-soot environments typical of EGR-equipped commercial engines.
→ Superfinished Guide Surface: The guide is superfinished to Ra ≤ 0.08 µm, ensuring smooth needle movement and consistent injection timing.
→ Flow-Balanced Orifices: The 8 holes are laser-drilled and flow-balanced to a hole-to-hole variation of less than 1.5%, ensuring symmetrical spray and even combustion across the cylinder.
→ High-Flow Seat Geometry: The seat diameter of 4.0 mm provides a larger sealing area, distributing the needle impact force and reducing seat erosion over time.
