Breather system ducting

In Simple Terms

This rule governs the tubes and pipes that allow air to escape from the engine's breather system. These ducts must be properly designed and routed to a specific outlet point defined elsewhere in the regulations, ensuring consistent and safe venting of engine gases.

• Breather ducting connects the Power Unit to a designated exhaust orifice
• All ducting must comply with structural and routing specifications
• Proper venting prevents pressure buildup in the engine
• Ducting design is part of overall Power Unit homologation
