Burns Unburned Exhaust Gases
The leading dream of an automotive catalytic converter is to burn unburned engine exhaust gases exiting a vehivle's engine. Engine combustion is not an exact science; thus, during general engine transaction, there are microscopic bits of unburned fuel that amuse pushed gone a automobile's engine during the exhaust stroke of an engine cycle. When this happens, the unburned fuel flows down a vehivle's exhaust conduit on its expedient to the automobile tail drainpipe, where it would purchase released into the gone air. A catalytic converter, which looks nearly Equal to a automobile muffler in shape and immensity, is all-inclusive with limited charcoal-like pellets called catalyst which incline super-heated as exhaust Gauze flows pas them. These super-heated pellets behave with the unburned Gauze molecules in a motorcar's exhaust and simply reburn them, turning them into mild inundate and carbon dioxide molecules.
Makes Unleaded Gasoline Use Mandatory
Cars equipped with catalytic converters must be operated with unleaded petrol alone. This is due to the constrictive effects that a catalytic converter has on exiting engine exhaust gases; the charcoal pellets combined with the small exhaust tubing within a catalytic converter slows down the speed at which exhaust gases exit an engine. Due to this slowing down of engine exhaust gas flow, a car's engine has slightly more time in which to adequately combust, or burn, it's air/fuel mixture, a process that results in slightly cleaner exiting engine exhaust gases. So, not only do catalytic converters help to make engine exhaust gases cleaner, they automatically require the use of cleaner gasoline to start with.
Retards Exhaust Gas Flow
Catalytic converters create a small amount of back pressure within a car's engine. Unleaded petrol, due to its absence of leadership, is a even cleaner and environmentally-friendly fuel than leaded petrol. Lead is toxic to the environment and toxic to human health. The catalyst material used in catalytic converters, usually consisting of small platinum-coated charcoal pellets, are highly-sensitive to lead-based gasoline and would quickly be ruined and rendered ineffective if exposed to leaded gas. Therefore, catalytic converter-equipped cars are designed to run on unleaded gasoline only, a gasoline that is inherently cleaner and less toxic than leaded gasolines.
