Product Introduction
In common rail diesel systems, the nozzle's opening and closing characteristics directly influence the rate of pressure rise in the combustion chamber – a parameter that determines both the engine's audible signature and its low-speed drivability. The Liwei M0032P150 is a precision-ground nozzle engineered with a controlled needle lift profile that reduces the impact velocity of the needle on the seat during closure, minimising the pressure oscillations that contribute to diesel knock at idle. This results in a noticeably smoother idle and reduced combustion noise – a significant advantage for vehicle owners who prioritise refinement in urban driving conditions. With a 7-hole configuration and 0.190 mm diameter orifices, the M0032P150 delivers a static flow of 870 cc/min at 100 bar, matching the fuel requirements of 2.0L to 2.2L diesel engines across the Ford Duratorq, PSA HDi, and BMW N47 platforms. The nozzle features a 150° spray angle, providing balanced atomisation for emissions-compliant engines.

◆ Construction Features
→ Controlled Needle Lift Profile: The needle is manufactured with a precision-machined lift stop that absorbs kinetic energy during closure, reducing the impact velocity by approximately 15% compared to standard nozzles. This damping effect translates to a quieter idle and reduced combustion harshness.
→ DLC Coating: The 1.5 µm diamond-like carbon coating reduces friction and extends service life.
→ Superfinished Guide: The guide surface is superfinished to Ra ≤ 0.08 µm.
