The rotten egg smell coming from your engine is likely due to a malfunctioning catalytic converter, part of the vehicle’s emissions control system. When functioning correctly, the catalytic converter transforms hydrogen sulfide in the exhaust into odorless sulfur dioxide. However, if it’s failing or clogged, it can’t process these gases effectively, leading to that distinctive sulfuric, rotten egg smell. This malfunction could be due to a variety of reasons including poor maintenance, engine misfires, or using the wrong type of fuel. It’s important to address this issue promptly as it not only impacts your vehicle’s performance and fuel efficiency but can also lead to more significant and costly damage over time. Consulting with an automotive professional for a diagnosis and repair is advisable to ensure your vehicle is both safe and compliant with emission standards.
