Platinum Bright

Run your own catalytic converter workshop. Exhaust gas streams flow through your honeycomb bed as three pollutants: amber CO, violet NOx and green HC. Balance intake temperature and air-fuel ratio so all three conversion rates hit the order targets at the same time.

Watch the physics: too cold and the bed never lights off, too hot and the catalyst sinters and dies. Lead-sulfur contamination fouls the bed over time, so burn it clean with regeneration before efficiency collapses.

Fill orders for tougher vehicles, earn coins, and upgrade with six real workshop parts: Palladium Coating, Ceramic Honeycomb, Thermal Shield, Regen Additive, Oxygen Sensor and the Platinum Core. Each part changes the game for real.
