Frequently Asked Questions Ask APW
How can a new catalytic converter improve the emission of a Nissan Altima?
Answer: A catalytic converter is just one of the components responsible for a vehicle's emission. If the engine is bad and underperforming, or if the wheels lack enough air pressure, the general emission will be affected. Also, contaminants in the converter will affect the part's performance; this is why the clogging of unburnt fuel in the converter must be prevented. If a bad emission is caused by a deteriorated cat, then a new one will certainly improve the quality of the car's emission. A new cat will be able to efficiently convert the by-products of burnt fuel into less toxic substances.
How can a Nissan Altima catalytic converter provide a lasting performance?
Answer: A catalytic converter performs better with quality fuel and excellent vehicle maintenance. Using only lead-free gasoline will definitely lessen contaminant buildup in the cat. Also, installing the cat away from a high-temperature area underneath the car will prevent faster performance deterioration. To make a cat converter last longer when it comes to performance, regular tune-ups of the induction, ignition, and engine systems must be conducted.
How can the efficiency of a catalytic converter on a Nissan Altima be determined?
Answer: There is a specific formula in measuring the efficiency of a catalytic converter, and the variables include the amount of gas coming in and coming out of the converter. Basically, the in level is deducted from the out level, and the difference is divided by the out level and the result is multiplied by 100. Thus, a catalytic converter with an upstream emission of 75 and a downstream of 5 will have an overall efficiency of 93%. The efficiency of a catalytic converter can be determined by getting an emission test at a local testing center accredited by the state.
How often should the catalytic converter on a Nissan Altima be replaced?
Answer: A Nissan Altima catalytic converter must be replaced as soon as its efficiency falls below 90%. Years of driving actually deteriorates the catalytic converter's efficiency, so it is expected that a replacement is necessary four years from the purchase date of the vehicle. Also, black or white smoke coming out of the tailpipe is a good sign for a cat replacement. The emergence of dirty smoke can be stalled by ensuring that the engine has an adequate air-fuel ratio, the injectors provide excellent fuel atomization, and the engine cylinders provide the same output, among others.
