Catalytic Converter Icon - Emission Control System Symbol #3455490 (License: Personal Use)

This yellow line-art icon represents a catalytic converter, a critical emissions control device in internal combustion engines. The central grid of circles symbolizes the ceramic honeycomb substrate coated with precious metal catalysts (e.g., platinum, palladium, rhodium), while the left-to-right arrow indicates exhaust gas flow through the unit. Designed for clarity in dashboards, manuals, and diagnostic tools.

Commonly used in automotive repair websites, OBD-II scanner interfaces, vehicle service manuals, and educational content about emission systems. Matches user intent for understanding check engine light codes (e.g., P0420) or learning how catalytic converters reduce CO, HC, and NOx.
