The smell of exhaust in a car can be downright dangerous and absolutely indicates a problem that needs to be addressed as soon as possible. If the driver or any occupants experience eye irradiation due to the fumes, the emission levels are outside of accepted safety levels and could be a danger. If the smell of exhaust in the car is an ongoing problem, there is most likely a leak in the exhaust system. A rotten egg smell coming from the exhaust port can indicate an issue with the catalytic converter. A heavy gasoline smell coming from the tailpipe could be the result of a failing oxygen sensor and something as simple as a degraded door seal that is letting in exhaust can lead to an exhaust smell in the cabin. Regardless of the cause, exhaust can be deadly and the vehicle should be inspected immediately. The exhaust system carries away the spent gases that are produced by the engine combustion. It is made up of a number of different components. Exhaust Manifolds: Exhaust manifolds are connected to the cylinder head and are responsible for engine air intake. Exhaust manifolds vent the cylinders exhaust by combining it all into one pipe. Oxygen Sensors: Oxygen sensors measure the ratio of oxygen to exhaust and transmit this information to the vehicle computer so it can adjust the amount of fuel being added to the air going into the engine. Catalytic Converter: The catalytic converter changes carbon monoxide and hydrocarbons into water and carbon dioxide, which is more environmentally friendly. Catalytic converters are required by almost all states. Muffler: The muffler reduces the noise that is created by the various explosions happening in the engine. Exhaust Pipe: The exhaust travels through the components listed above and then passes into the exhaust pipe and is sent out into the air.
