Are there any cars that have 2 catalytic converters?

Question

Why is that?

Answer 1

Yes there are a number of cars that have a 2 catalytic converters. the reason, cleaner exhaust. A catalytic converter uses a catalyst to help burn unburned fuel. They act as a scrubber on the car to clean what is coming out of the engine. the reason some cars have 2 is to clean different gases that come out of the car. you have NO (Noxious Oxide) gas CO (Carbon monoxide) Hydrocarbons, and CO2. what you want coming out of the car as much as possible is the CO2. the cats help to reduce all the other gases from the unburned fuel of the car.

Answer 2

yes. chevrolet with v-8 engines.Ford with V-8 engines. some vehicles have a huge catalytic converter built in and engineers later found out that it increase the temperature which cause the floor or carpet to get hot and reduce the shorten the lifetime of the converter. to solve this problem, they make the catalytic converter smaller and install it on each exhaust pipes. this design also increase horsepowers.

Answer 3

My advice is to take it decrease back to an analogous save to verify it incredibly is not any longer an analogous situation. it fairly is available that interior the cat. conv. restore, the somewhat some connectors to a sensor could gotten loose and led to a adverse connection. even nonetheless, in the event that they declare that it fairly is a sparkling situation and not with regard to the previous restore, request a duplicate of the codes saved if available on the artwork order. Then tell them thank you for checking it out and which you will reschedule an appointment to have them do the maintenance or something like that. however the plan is to get a 2d opinion from a great restore save and get there comments on the region. additionally provide them the restore historic previous so as that they are able to study and evaluate what they got here across. As far your question in the journey that your vehicle has 2 cat. conv. i'm assuming that your engine is a V6. meaning that there are 3 cylinders in line with cat. conv.

Answer 4

Some do have 2 some 4 some 1. Depends on different things. Rover and BMW for instance use 4 cats on their V8 motors mostly for space. The size of a single cat for each side is to big so they use two smaller ones.

Answer 5

Yes some companies use one for each bank on a vee style engine others use the forward cat to convert hydrocarbons and carbon monoxide to carbon dioxide while the second cat breaks down oxides of nitrogen. Many companies use a 3 bed cat and require only one. The design depends on how the company feels it best meeets IM requirements

Answer 6

Yep, there's lots. Typically because they're running true dual or part dual exhaust (performance vehicles) so they need a catalytic converter for each side to meet emissions standards.

Answer 7

Corvettes often have two catalytic converters.

Answer 8

yes, alot have 2 some have 4
what kind of car are you talking about?
some are what is called a pre-cat and a post cat
pre cats heat the exhaust system to help the post or main cat "light off" faster to clean emissions

Answer 9

Yes, there are.
Usually they are V6 or V8 engines, with dual exaust pipes.
One converter for each pipe line.

Answer 10

MOSTR CARS DO HAVE 2 CATS SMALLER CARS DONT BIGGER ONES DO
