AI Technical Summary

Technical Problem

In the prior art, the cavitation design of the lubricant injector has not been effectively utilized, resulting in unstable spray and uneven distribution of lubricating oil, which affects the lubrication effect of large two-stroke engines.

Method used

By introducing asymmetric cavitation into the nozzle of the lubricant injector, the direction and distribution of the spray are controlled. The cavitation bladder forms an asymmetric structure in the nozzle, ensuring that the lubricant evenly covers the cylinder liner.

Benefits of technology

It achieves stable, controllable injection and uniform distribution of lubricant, improves lubrication effect, reduces the demand for piston rings, and optimizes the SIP lubrication system.
