Description

What does a housing oil nozzle do?

This engine component plays a critical role in the lubrication and cooling system of a heavy commercial vehicle engine. By spraying pressurized oil directly onto the underside of the piston, it effectively removes heat accumulated from the combustion chamber, helping to maintain thermal balance and prevent premature wear.

Compatibility and engine fitment

This specific housing oil nozzle is compatible with Mercedes-Benz engines. It is engineered to meet exact OE dimensions to ensure correct spray patterns and pressure management within the engine block gallery.

Installation and maintenance guidance

For professional installation, technicians should verify the connection style—whether it be a bolted flange, banjo connection, or threaded body—to ensure a proper seal. It is vital to match the spray tube angle and check valve pressure specifications to prevent oil from hitting the cylinder liner instead of the piston base.

Troubleshooting and selection

Maintaining correct oil pressure and inspecting these nozzles during engine overhauls can prevent serious issues like piston ring sticking or bearing failure. Always consult your authorized distributor for precise fitment confirmation.

OE cross-reference

0101 026 (Housing Oil Nozzle Crankcase) is the equivalent of the Mercedes-Benz OE number. This part directly replaces Mercedes-Benz OE number 4221800043.

FAQ

What is the primary function of this oil nozzle?
The nozzle sprays pressurized oil onto the underside of the piston to dissipate heat and provide lubrication to the piston pin area.
How can I ensure this nozzle fits my engine?
You must verify the connection style (such as banjo or threaded) and ensure the spray tube angle matches your specific engine code.
What are the risks of using an incorrect nozzle?
An incorrect geometry or angle can cause oil to hit the cylinder liner rather than the piston base, leading to overheating or block damage.
Does this part support thermal management?
Yes, by removing heat from the piston crown, it helps maintain thermal balance in high-load, turbocharged engines.
What are the OE reference numbers of this part?
0101 026 directly replaces Mercedes-Benz OE number 4221800043.
