Description

What does a housing oil nozzle do?

This engine component is vital for maintaining thermal balance within heavy-duty diesel 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 overheating during high-load operations.

Compatible vehicles and engines

This specific part is compatible with Mercedes-Benz vehicles. It functions as a precision component within the crankcase, ensuring that oil is directed exactly where needed to protect the piston pin and connecting rod bushings from excessive friction.

Installation and maintenance

When replacing this part, technicians should verify the connection style—whether it be a bolted flange, banjo connection, or threaded body—to ensure a perfect seal. It is essential to match the spray tube angle and check valve opening pressure to the original specifications to prevent oil from hitting the cylinder liner instead of the piston base.

Selection guidance

Regular inspection of oil nozzles during engine overhauls can prevent premature piston wear. Ensuring correct installation helps maintain stable gallery pressure and prevents potential engine damage caused by insufficient cooling.

OE cross-reference

0101 030 (Housing Oil Nozzle Crankcase) is the equivalent of the Mercedes-Benz OE number. This part directly replaces Mercedes-Benz OE number A4601801943.

FAQ

What is the function of a housing oil nozzle?
The nozzle sprays pressurized oil onto the underside of the piston to remove heat from the crown and provides lubrication to the piston pin area.
Can I use any oil nozzle for my Mercedes-Benz engine?
No, selection must be based on the specific engine code and connection style to ensure correct spray angle and pressure management.
How can I identify if an oil nozzle is failing?
Symptoms may include insufficient cooling or drops in gallery pressure. Technicians should check for proper spray direction and seating.
What happens if the wrong nozzle angle is installed?
An incorrect angle can cause oil to strike the cylinder liner wall instead of the piston base, leading to improper cooling and potential damage.
What are the OE reference numbers of this part?
0101 030 directly replaces Mercedes-Benz OE number A4601801943.
