Common Misconceptions About Ammonia Smells From Automobile Exhausts

When it comes to the unpleasant and often dangerous odor of ammonia in automobile exhaust, there are several common misconceptions that people tend to have. One of the most common is that oil burning is responsible for the smell. While oil burning can lead to an increase in ammonia, it is not the only factor; other elements such as fuel composition and oxygen levels also play a role. Another misconception is that the smell must be coming from inside the engine, but this is simply not true. Ammonia smells can actually come from outside sources such as leaking gasoline or oil.

Misconceptions About Common Causes

Another misconception about ammonia smells from automobile exhausts is that they are caused by a problem with the catalytic converter. While the catalytic converter can become clogged or damaged, this is not necessarily always the cause of an ammonia smell, as other components such as spark plugs and oxygen sensors can be at fault as well. Additionally, some vehicles are simply more prone to producing these odors due to their design or fuel type.

Misconceptions About Repair Options
