From the main bearing gallery, oil is diverted through small passages to reach the oil jets. The primary targets are usually the underside of the piston crowns and the connecting rod bearings, areas subjected to immense pressure and heat.
Hydrodynamic Film: How Oil Jets Create Critical Lubrication Layers
Contribute to longer engine life by preventing premature bearing and piston damage. The Mechanics of Oil Jets To understand how these components function, one must look at the oil delivery system as a whole.
Ensure consistent lubrication for small, critical bearings that splash oil might not reach. When an oil jet becomes obstructed, the component it serves is starved of lubrication, leading to increased friction, overheating, and potentially scored journals or seized pistons.
Hydrodynamic Film Formation by Oil Jets
Maintenance Implications and Considerations Because oil jets are integral to the engine's internal lubrication, any issue with the oil delivery system can have severe consequences. Unlike passive oil circulation that relies on splash lubrication, these jets actively spray a focused stream of pressurized oil onto critical components.
