Why Does My Engine Smell Like Sulfur?

When driving, smelling a strong odor such as sulfur — also known as ″rotten eggs″ — is often an indication of a serious problem with the vehicle. The scent is caused by a small quantity of hydrogen sulfide, sometimes known as sulfur, present in the gasoline. Typically, hydrogen sulfide is converted into odorless sulfur dioxide by the body.

When gasoline reaches the catalytic converter, it begins to convert the hydrogen sulfide present into sulfur dioxide, which is harmful to the environment. As a result, the catalytic converter will not be able to handle the gases as efficiently as it should, resulting in the stench of rotten eggs. This will need the purchase of a new catalytic converter.
