Exhaust gas pollution exhaust sources in various large-scale industrial facilities such as petroleum refineries, natural gas processing plants, petrochemical plants and chemical production plants. However, these are often referred to as flue gases. Catalytic converters in cars intend to break down the pollution of exhaust gases using a catalyst. Scrubbers in ships intend to remove the sulfur dioxide (SO) of marine exhaust gases. The regulations on marine sulfur dioxide emissions are tightening, however only a small number of special areas worldwide have been designated for low sulfur diesel fuel use only. One of the advantages claimed for advanced steam technology engines is
Aftermarket exhaust parts pipe or the pipes temporarily merge. This is to equalize the pressure in both exhaust pipes. Exhausts emit a large amount of heat into the engine bay, which can have a negative effect on engine performance by raising the underhood temperatures. As a result, high temperature insulation is used, more commonly known as heat barriers, for exhaust heat management. Thermal barrier ceramic-coatings are specifically designed to reduce heat loss from engine exhaust system components including exhaust manifolds, turbocharger casings, exhaust headers, downpipes and tailpipes. When used under-bonnet, these have the positive effect of reducing engine bay temperatures, therefore lessening the
