Highlight the Benefits of Using 3-Way Catalytic Converters
3-way catalytic converters are effective ways of reducing harmful pollutants like carbon monoxide, unburnt hydrocarbons and nitrous oxides by converting them to less harmful gasses. They work best when the engine operates within an ideal air/fuel ratio range that approximates stoichiometry.
Clean air can not only benefit your lungs, but it can also extend the lifespan of your engine – meaning fewer visits to repair shops and lower long-term expenses for you.
Cleaner Emissions
Modern catalytic converters employ precious metals such as platinum, palladium and rhodium to oxidize and reduce harmful emissions such as carbon monoxide, hydrocarbons and oxides of nitrogen from an engine exhaust system into less harmful gases that are then expelled via its tailpipe.
The catalyst consists of a ceramic block designed to provide a large surface area for gases to pass over, while blowing them over precious metals which promote oxidation and reduction reactions in order to filter toxic fumes from entering.
Three way catalytic converters differ from two-way converters by also reducing oxides of nitrogen emissions. They do this by mandating that fuel mixture be lean enough to facilitate CO and HC oxidation while at the same time decreasing NOx levels with oxygen sensor feedback control, maintaining an air/fuel ratio near stoichiometry to maximize pollution conversion efficiency without polluting engine performance further.
Improved Fuel Efficiency
Vehicle emissions produce fumes and gases known as emissions when operating, contributing significantly to air pollution such as photochemical smog and low-level ozone that may pose respiratory risks.
To combat this issue, vehicles are equipped with catalytic converters. These devices can convert toxic exhaust into less toxic chemicals through redox reactions by oxidizing and reducing harmful substances like carbon monoxide, hydrocarbons, and nitrogen oxides.
Two-way catalytic converters were common on cars prior to 1981. These devices contained oxidation catalysts to convert carbon monoxide and unburned hydrocarbons to carbon dioxide and water while simultaneously reducing nitrogen oxides produced when fuel was burned by engines into oxygen and water.
INTERKAT three-way catalytic converters feature platinum-rhodium precious metal coatings evenly applied over a washcoat, before being adhered onto a metallic alloy core for maximum exhaust emission efficiency of up to 98%.
Extended Engine Life
Three-way catalytic converters help protect us by converting harmful pollutants to less dangerous compounds such as carbon dioxide and water vapor, acting like environmental superheroes by decreasing air pollution levels and leading to decreased allergies, asthma attacks and respiratory problems.
Inside a converter, platinum and palladium precious metals are evenly dispersed across a ceramic honeycomb structure, serving as catalysts that convert exhaust gasses from the vehicle into less hazardous emissions such as carbon monoxide or unburnt hydrocarbons. Nitrous oxides are also reduced by being converted to nitrogen and oxygen via this process.
To achieve optimal gasoline engine operation, the air-fuel ratio needs to be maintained within a narrow range around stoichiometry. Oxygen sensors and onboard diagnostics can be used to monitor this ratio; some three-way catalyst systems also feature upstream air injection systems which add oxygen into fuel mixture before entering catalytic converter. This prevents lean air-fuel mixtures from damaging converters while offering optimal performance.
Compliance with Regulations
Catalytic converters reduce emissions from internal combustion engines fueled by gasoline, diesel or alternative fuels such as ethanol. You’ll find catalytic converters in cars, trucks and other vehicles as well as generators, lawnmowers and water pumps; their use helps ensure compliance with government regulations regarding engine emissions.
Three-way catalytic converters oxidize carbon monoxide (CO), hydrocarbons and nitrogen oxides and reduce them by up to 99 percent, making gasoline engines suitable for this technology with air/fuel ratios near stoichiometry the optimal application. Modern cars feature oxygen sensors which continuously monitor this mixture to adjust it between lean and rich conditions for maximum pollutants reduction.
3-Way converter catalysts are composed of precious metal coatings of platinum, palladium and rhodium that are evenly dispersed over an uniform high porosity washcoat surface. This advanced technology enables pollution conversion efficiencies of over 98% while keeping temperatures and pressures low at the catalyst surface – leading to clean, safe and quiet exhaust systems.
