Why diesel engines rely so heavily on crankcase breathing systems
Diesel engines generate higher blow-by because of their compression ratios, making closed crankcase ventilation systems especially important for controlling pressure, emissions, and oil contamination.
Key Takeaways
- Crankcase breathers vent blow-by gases and prevent pressure buildup inside engines.
- Diesel engines need especially robust systems because higher compression increases blow-by.
