Description

What does a housing oil nozzle do?

This housing oil nozzle is a critical component within the engine crankcase system, specifically designed to facilitate piston cooling and lubrication in heavy commercial vehicle engines. By spraying pressurized oil onto the underside of the piston skirt, it effectively carries heat away from the combustion chamber and into the sump, preventing thermal damage during high-load operations.

Compatibility and engine function

This specific part is compatible with Mercedes-Benz engines. It functions as part of the lubrication circuit, where the oil is drawn from the sump and distributed through the main gallery. The nozzle ensures that even under intense thermal stress, the piston crown remains within safe operating temperatures, which is vital for preventing piston ring sticking and maintaining engine longevity.

Installation and maintenance guidance

When performing installation, technicians should verify the connection style—whether it is a bolted flange, banjo-connected, or a threaded body—to ensure a perfect seal. It is essential to match the spray tube angle and valve opening pressure to the original requirements to prevent oil from hitting the cylinder liner instead of the piston base. Always consult your authorized distributor for precise fitment guidance.

Selection and troubleshooting

Correct selection is vital to prevent drops in main gallery pressure or forced fittings that could damage the engine block.

OE cross-reference

0101 028 (Housing Oil Nozzle Crankcase) is the equivalent of the Mercedes-Benz OE number. This part directly replaces Mercedes-Benz OE number 5411800743.

FAQ

What is the primary function of this oil nozzle?
It sprays pressurized oil onto the underside of the piston to provide essential cooling and lubrication for the piston pin and connecting rod.
Can I select a nozzle based only on visual appearance?
No. Even similar nozzles can differ in spray angle or check valve pressure; always verify using the engine code and OE reference.
What happens if an incorrect nozzle is installed?
An incorrect angle can cause oil to hit the cylinder liner rather than the piston, leading to insufficient cooling and potential engine damage.
How does this component assist in thermal management?
By directing oil flow specifically to high-heat zones, it helps balance thermal loads in turbocharged engines and prevents ring sticking.
What are the OE reference numbers of this part?
0101 028 directly replaces Mercedes-Benz OE number 5411800743.
