Hyundai Santa Fe - a mid-size crossover of South Korean production, produced from 2000 to the present.
The first generation was produced from 2001 to 2007. The car was aggregated with four-cylinder gasoline engines with a volume of 2.4 liters and a V6 with volumes of 2.7 and 3.5 liters. The exhaust system of the in-line engine machine had two catalysts - one on the manifold with two lambda probes, and the second under the bottom without oxygen sensors. On versions with V-shaped catalyst engines, three were installed - two on each side of the engine and a third under the bottom. There was a two-liter turbodiesel version, on which a particulate filter was installed.
Since 2006, the second generation of the Hyundai Santa Fe goes into production. The modern, more sporty exterior of the model has received consumer approval. The car was aggregated with the following engines: gasoline V6 with volumes of 2.7 and 3.3 liters and power of 185 hp. and 242 hp respectively and a turbocharged diesel with a volume of 2.2 liters with a power of 200 hp The arrangement of the catalysts on cars with a 2.7-liter gasoline engine is similar to the previous version, on the car with a 3.3-liter engine, another catalyst was added, a diesel particulate filter was still installed.
In 2012, the third generation of the crossover was presented. The car is aggregated by gasoline turbocharged engines with volumes of 2.0 and 2.4 liters, V6 with a volume of 3.3 liters, as well as turbodiesels with a volume of 2.0 and 2.2 liters. Transmission six-speed mechanics or automatic.
What you need to know when replacing the catalyst
Any catalyst can be replaced with a flame arrester, but for this it is necessary to "trick" the second lambda probe. To do this, there are tricks, special devices that allow you to create conditions for receiving the desired signal from the second sensor, or change its value and only then "give" them to the electronics.
The deceptions of the first type are called mechanical (spacers under the lambda probe, mini-catalyst, screwdriver under the second lambda), and the second - electronic (made in the form of microcircuit). Theoretically, a car can be flashed under EURO-2, but there are very few places where this can be done without consequences for the engine.
Another solution is to install universal catalysts. They are much cheaper than the original due to a simpler design. Manufacturers of universal catalysts assure that their resource is not inferior to the original products. In practice, it turns out that this is not entirely true. The resource of only the best manufacturers - Eberspacher, Bosal and some others is about 80 - 90%, that is, almost the same as the original. The rest of it is much lower.
