FAQ

Q1: What is the difference between DLLA150S308 and other series like DLLA160S255?
A: The primary difference lies in the spray angle (e.g., 150° vs. 160°) and flow rate specifications. The DLLA150S308 is optimized for engines requiring a 150-degree spray angle, while DLLA160S255 suits engines with different combustion chamber designs. Always match the part number to your engine’s OEM requirements for proper fitment.

Q2: Can this nozzle be installed without professional calibration?
A: While the nozzle is a direct replacement, we recommend professional installation by a qualified diesel technician. Proper calibration of opening pressure (typically 220-260 bar) and spray pattern verification is essential to prevent engine knocking, excessive smoke, or reduced power output. Our nozzles are pre-tested, but final adjustment may be needed based on your engine’s condition.

Q3: How can I ensure compatibility with my diesel engine before ordering?
A: Check your existing nozzle’s part number (e.g., stamped on the side) and compare it to our cross-reference list. Alternatively, provide us with your engine model (e.g., 4HK1, 6WG1, S6S) or vehicle VIN, and our technical support team can confirm fitment within 24 hours. We also offer sample testing for bulk orders to ensure 100% compatibility.
