Изоляция верхней части открытой системы вентиляции картера Caterpillar 4457995

The Open Crankcase Ventilation Top Insulation is a thermal barrier aimed to cover and protect the upper portion of the crankcase ventilation assembly. It limits heat transfer from surrounding engine components, helping stabilize operating temperatures within the ventilation system. This helps reduce condensation, prevent premature wear, and support consistent vapor flow. The insulation fits tightly over the top housing section, maintaining its shape and effectiveness even during high-temperature cycles. Its layered structure resists thermal degradation, vibration, and exposure to engine fluids.Attributes:• Shields canister top from direct thermal contact or radiant heat.• Supports steady airflow in the crankcase vent path.• Attached using clips, adhesive, or molded retention features.Applications: The Open Crankcase Ventilation Top Insulation is installed over the top section of open crankcase ventilation systems to manage surface temperature and protect airflow integrity. It helps to maintain consistent system function by preventing heat-related disruptions, particularly in thermally intense engine environments.
