Product Introduction
In diesel engine design, the nozzle's orifice diameter determines the fuel flow rate, while the spray angle governs fuel distribution within the combustion chamber – these two parameters must be carefully balanced to achieve complete combustion without exceeding particulate emission limits. The Liwei V0203P152 is a precision-ground nozzle engineered with a 152° spray angle and a 7-hole configuration featuring 0.190 mm diameter orifices – a geometry that provides a static flow of 870 cc/min at 100 bar, delivering the fuel volumes required for 2.2L to 3.0L diesel engines in passenger car and light commercial applications. The 152° spray angle ensures the fuel cloud remains within the bowl boundaries of modern Euro 5/6 pistons, reducing wall wetting and improving air utilisation, while the 0.190 mm orifices provide fine atomisation (SMD ≈ 22 µm) for complete combustion.
