Platinum content in catalytic converters can differ significantly depending on the year the catalytic converter was fabricated and the type of vehicle. Small cars usually average 1 to 2 grams per car, while larger trucks can have as much as 12 to 15 grams.Continue Reading
Catalytic converters are a nonhomogeneous product; there are broad spectrum variances in metallurgic makeup and consistency. Composition is dependent on engine displacement and type of fuel used. Varying market prices for platinum and supply and demand fluctuations have impacted the amount of platinum used in catalytic converters over the years, as it is really a ratio or mixture of platinum, palladium and rhodium. This platinum metal mixture is commonly referred to as PGMs, or platinum group metals.
Catalytic converters are part of the vehicle emissions control system and are used in internal combustion engines, whether fueled by gasoline or diesel. Platinum functions as a catalyst to accelerate chemical reactions used to convert harmful vehicle emissions into less harmful substances. The catalytic converter was first invented by French mechanical engineer Eugene Houdry in the 1950s, who was prompted into his research by early studies of smog in Los Angeles. However, the first official catalytic converter in production for automobiles was not developed until 1973.Learn more about Car Parts & Maintenance
Catalytic converters use a reduction and an oxidation catalyst organized in a honeycomb structure to react with the harmful emissions present in exhaust gas. The reduction catalyst converts nitrogen dioxide into nitrogen and oxygen, while the oxidation catalyst converts the unburned hydrocarbons and carbon monoxide into carbon dioxide.Full Answer >
To clean a catalytic converter, pour catalytic converter cleaner into the gas tank, drive until the tank is close to empty, refill the tank, and re-calibrate the vehicle's on-board computer. This helps to maintain components while reducing pollution emissions and eliminating foul smells.Full Answer >
Symptoms of a bad catalytic converter in a Dodge Dakota, or any vehicle, include exhaust issues and poor performance. Drivers also notice an offensive smell coming from the vehicle, similar to rotten eggs or sulfur.Full Answer >
A catalytic converter operates normally between 550 and 1,600 degrees Fahrenheit with the optimal temperature being about 806 degrees. Pollutants coming through the exhaust system can raise the temperature over 2,000 degrees Fahrenheit, at which point, the catalytic converter can be severely damaged.Full Answer >
