Carbon is a by-product of car engines that contributes to the development of greenhouse gases. Further, it can leave deposits on the insides of the engine and exhaust system. Some people believe that decarbonising is not necessary with a modern vehicle. However, for older vehicles, removing the carbon could improve performance.
Use a chemical spray designed to remove carbon deposits. According to Ecotek Technologies, their PowerBoost Engine Energizer eliminates carbon in the engine and exhaust system. Uncouple the air intake and spray the can into it with the engine revving, for about eight minutes. Then go for a drive.
Buy an exhaust filter, such as the Flow Through Exhaust Filter by Industrial Environmental Carbon. This will capture carbon dioxide in the exhaust system and prevent carbon build-up. Have the filter fitted into your tailpipe. Change the filter periodically to ensure the system continues to work effectively.
Fit an Algae Mobile device to your car for an environmentally friendly approach to the problem of removing carbon from the car exhaust. Unlike the PowerBoost Engine Energizer the Algae Mobile is a chemical free product. It uses a biological agent -- namely algae -- to change carbon dioxide into oxygen. Further, unlike the Flow Through Exhaust Filter, you can fit the Algae Mobile yourself. Simply insert it into your tailpipe and fix it in place.
