Catalytic converters were invented with the purpose to reduce the quantity and increase the quality of emissions released in the air. With the increase in car sales and the usage of cars, it has become more and more important to ensure that we all still have fresh air to breathe. So, it seems that these devices can only bring advantages, but there are a few downsides that come with their usage as well, such as:
- Decreased horsepower – the engine uses more energy for the converter and for burning the elements;
- Reduced gas mileage – again, the catalyst slows down the circulation process of the emissions leading to a higher consumption of fuel;
- Engine overheating – from the additional need to burn more.
But, still, considering the major side effects of not using such devices, meaning the reduction of oxygen, it is important to have a car with such a device. The cost of this feature amounts to 2% of the total car price. Also, an older study shows that catalytic converters reduce health costs not just for car owners but for all those around.
