FAQ

Q1: Is this nozzle compatible with my Bosch injector body?

A: The DLLA155SM194 is a standard Bosch-style nozzle code. It is designed to fit most common Bosch injector bodies that accept this size. However, we recommend verifying your injector’s specific body type (e.g., Bosch P, DN, or DLLA series) and the original nozzle code before purchase.

Q2: What is the installation procedure for this nozzle?

A: Installation should be performed by a qualified diesel technician. Key steps include: (1) Cleaning the injector bore thoroughly. (2) Replacing the nozzle retaining nut and copper washer. (3) Torquing the nozzle to the manufacturer’s specification (typically 60-80 Nm). (4) Testing for leaks after installation. Improper installation can cause engine damage.

Q3: How can I ensure the correct flow rate for my engine?

A: The DLLA155SM194 code specifies a specific flow rate and spray angle. If you are unsure, you can check your current injector’s nozzle code (often stamped on the side) or consult your vehicle’s service manual. For modified or tuned engines, you may need a different flow rate. Our technical support team can assist with cross-referencing if you provide your engine’s model and year.
