Product Introduction
In the diesel aftermarket, one of the most persistent challenges for workshops and fleet operators is the proliferation of nozzle variants – each injector family typically requires a specific orifice geometry, spray angle, and flow rate, making inventory management complex and costly. The Liwei M0061 addresses this challenge through a universal fitment design – a nozzle geometry that accommodates a broad range of Bosch CRI and Denso common rail injectors, reducing the need for multiple part numbers. This nozzle features a 7-hole configuration with 0.190 mm diameter orifices and a 150° spray angle – a geometry that matches the most widely used injector platforms in the 2.0L to 3.0L diesel engine segment. The defining metric of the M0061 is its flow tolerance, held to ±3% of nominal – a range that accommodates the ECU's adaptation capability while providing consistent performance across different injector bodies.
█ Application Coverage – Compatible Injector Platforms
The M0061 is designed to replace nozzles in the following common rail injector families:
Bosch CRI 1.0 / 2.0 / 2.2 – Injectors with 7-hole × 0.190 mm nozzle geometry, including 0445110059, 0445110060, 0445110270, 0445110290, 0445110601, and similar part numbers
Denso G2 / G3 – Injectors with 7-hole × 0.190 mm configuration, including 4CR01974 and variants
Vehicle Applications – Compatible with Volvo D5, Ford Duratorq 2.0/2.4, BMW M57/N57, Mercedes OM642, VW/Audi 2.0 TDI, Toyota D-4D, and similar platforms
The nozzle is a direct replacement for Bosch part numbers 0445110059, 0445110060, 0445110270, 0445110290, 0445110601, and Denso 4CR01974 nozzles. It is supplied as a bare nozzle – the needle and nozzle must be lapped together during assembly.
