Description

What does a housing oil nozzle do?

This housing oil nozzle plays a critical role in the lubrication and cooling system of heavy-duty diesel engines. By spraying pressurized oil directly onto the underside of the piston skirt, it effectively carries heat away from the combustion chamber and helps maintain thermal balance during high-load operations.

Engine compatibility and function

The component is specifically compatible with Mercedes-Benz engines. It functions by drawing oil from the main gallery to provide essential piston cooling and lubrication for the piston pin and connecting rod small-end bushing. This prevents excessive heat accumulation and reduces friction in heavy commercial vehicle engines.

Installation and selection guidance

For correct installation, technicians should verify the connection style and spray tube angle against the original part. Because different cylinder positions may require different tube angles, it is vital to match the component to the specific engine code to ensure the oil spray hits the piston base rather than the cylinder liner wall.

Maintenance and troubleshooting

Regular inspection of the oil nozzles can help prevent pressure drops in the main gallery. Ensuring a secure fitment in the engine block is essential for maintaining proper oil pressure and protecting internal engine components from thermal damage.

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 4421800343.

FAQ

What is the function of a housing oil nozzle?
It sprays pressurized oil onto the underside of the piston to provide cooling and reduce friction at the piston pin, which is vital for thermal management.
Which vehicles are compatible with this part?
This specific component is designed to be compatible with Mercedes-Benz heavy commercial vehicle engines.
How can I ensure I select the correct nozzle?
It is important to match the spray tube angle and connection type with the original part and use the specific engine code to guarantee correct fitment.
What happens if an incorrect nozzle is installed?
An incorrect angle or geometry can cause oil to hit the cylinder liner instead of the piston, potentially leading to engine damage or pressure loss.
What are the OE reference numbers of this part?
0101 026 directly replaces Mercedes-Benz OE number 4421800343.
