Engineering summary
Quick Answer
Larger intake holes can improve flow for thicker oil, but excessive intake area can increase leakage risk if the rest of the hardware is not designed around it.
Key Takeaways
- Intake size is a flow-control variable.
- Bigger is not automatically better.
- Oil-specific testing is required.
Flow path design
The intake opening controls how oil enters the heating area, but flow also depends on pressure balance, ceramic structure, and storage conditions.
