Product Introduction
In the high-pressure environment of a Common Rail system, the Injector Nozzle is the final frontier. It is the point where hydraulic potential energy is converted into kinetic energy. The Liwei M0061 is not just a "part"; it is a precision-engineered atomization device designed to dictate the efficiency of the combustion event.
While the injector body provides the housing, the M0061 nozzle assembly is responsible for the "Spray Characterization." In the context of "Diesel Not Fuel" (focusing on the mechanism), the M0061 acts as the gatekeeper. It must open and close within milliseconds, withstand pressures exceeding 1600 Bar, and ensure that every droplet of diesel is pulverized into a mist fine enough to burn completely.
System-Level Compatibility
The LIWEI M0061 nozzle is designed for integration into electronically controlled common rail diesel injection (CRDI) systems, widely used in:
Heavy-duty commercial vehicles
Agricultural machinery
Construction and off-road equipment
Marine auxiliary diesel engines
Industrial generator sets
Its compatibility extends to systems supplied by major global platforms such as Bosch-type architectures, ensuring OEM-level interchangeability and aftermarket adaptability.
Key Technical Data
While exact calibration depends on injector assembly, typical engineering benchmarks for M0061-type nozzles include:
Injection Pressure Range: 1600–2500 bar
Nozzle Hole Diameter: ~0.10–0.20 mm scale
Spray Angle: 145°–160° (diesel-specific geometry)
Multi-hole Configuration: Optimized for combustion chamber matching
Needle Lift Precision: Micron-level tolerance
Flow Coefficient Stability: Designed to resist cavitation-induced variation
These parameters ensure consistent atomization across multiple injection events per cycle.
Spray Physics & Combustion Efficiency
The real value of M0061 lies in spray atomization behavior:
High pressure transforms diesel into fine droplets with high surface-area-to-volume ratio
This enhances air-fuel mixing, improving combustion completeness
Multi-hole spray patterns ensure uniform cylinder distribution
Controlled spray angle prevents wall wetting and carbon deposits
Additionally, research shows that nozzle geometry asymmetry can influence spray penetration and velocity, making precision manufacturing essential
