Description

What does a housing oil nozzle do?

The housing oil nozzle plays a critical role in the engine lubrication system by directing pressurized oil toward the underside of the piston. By spraying oil onto the piston crown, this component effectively carries heat away from the combustion chamber, helping to maintain thermal balance and prevent component fatigue in heavy commercial vehicle engines.

Vehicle and engine compatibility

This part is designed to be compatible with LASO systems. When selecting a replacement, it is vital to match the specific spray geometry and connection type required by the engine block, as even minor variations in tube angle can impact cooling efficiency.

Installation and maintenance

Installation should be performed by a workshop technician to ensure correct torque and seating within the engine block. Proper installation prevents pressure drops in the main oil gallery and ensures that the spray hits the target area precisely. Always verify fitment against the engine code and original part specifications.

Selection guidance

Check the compatibility list.

FAQ

What is the function of a housing oil nozzle?
It directs pressurized oil onto the underside of the piston to remove heat from the combustion chamber and provide essential lubrication to the piston pin.
Can I select a nozzle based only on visual appearance?
No, because different spray tube angles or valve pressures can cause incorrect oil distribution. It is best to use the engine code and OE references.
What happens if an incorrect nozzle is installed?
Incorrect geometry can lead to oil hitting the cylinder liner instead of the piston, potentially causing overheating or insufficient lubrication.
How are these nozzles manufactured for durability?
They are made from high-strength components designed to withstand high pressure and thermal loads during heavy-duty operation.
What are the OE reference numbers of this part?
0101 026 directly replaces LASO OE number 20014303.
