When the gas pedal is pressed, the car emits a sound reminiscent of a lawn mower being started. Prolonged use of the gas pedal results in a scent similar to a loose belt. It appears that there might be a significant exhaust leak, which causes the release of untreated exhaust from the engine, potentially explaining the odor you are experiencing.

Can a catalytic converter issue cause a smell of ammonia in the car exhaust?

When the catalytic converter is not working properly, it is unable to effectively convert fuel into non-toxic compounds. This can lead to the presence of an ammonia smell in the exhaust. This occurrence is due to the production of sulfur dioxide and other pollutants during the conversion process. Additionally, the smell may also be caused by the presence of unburned hydrogen sulfide.

What does a bad catalytic converter smell like?

A functional catalytic converter is responsible for converting hydrogen sulfide into odorless sulfur dioxide.

If the catalytic converter is not working properly, a noticeable smell similar to rotten eggs, caused by sulfuric compounds, may come from the exhaust.

In addition to the unpleasant odor, a malfunctioning catalytic converter can result in unburned fuel in the exhaust, leading to dark smoke and potentially triggering the check engine light.

Can a bad catalytic converter cause higher fuel consumption?

Improper combustion of fuel and a clogged exhaust can reduce the efficiency of a car engine, requiring it to exert more effort to generate the same power.

In some cases, a faulty catalytic converter can result in reduced performance, although this is not always the case.

One of the symptoms of a bad or clogged catalytic converter is a noticeable sulfur smell.

Why is my catalytic converter rattling?

A clogged catalytic converter can limit exhaust flow and a cracked one can release hazardous gas. Both issues can have a negative impact on engine performance, resulting in reduced power and acceleration as well as decreased fuel efficiency.

Rattling noises coming from underneath the vehicle are also indicative of a faulty catalytic converter.

What role does the fuel mixture play in the emission of an ammonia smell from the car exhaust?

The presence of a high ammonia content (XNH3 > .6) and a low equivalent ratio has the potential to lower NO and CO emissions. An increase in ammonia content leads to a decrease in the molar fractions of H, O, and OH radicals, as well as the flame temperature. It is also observed that the reaction path of NO and CO production is significantly influenced by high temperature, high pressure conditions, and ammonia content.

Why does ammonia smell so bad?

Ammonia has the ability to disperse easily due to its lighter-than-air nature. It has a density that is 60% less than that of air, allowing it to remain airborne rather than settling in low lying areas like other dense odorous compounds such as hydrogen sulfide. As a result, the presence of ammonia odors is more noticeable on-site compared to off-site locations.

Is free ammonia escaping from the SCR?

The presence of escaping free ammonia from the SCR should be avoided. This indicates an excessive dosage of DEF, preventing complete processing in the SCR. A mild ammonia odor may not be concerning, but a strong ammonia smell is considered problematic. The extent of the issue will vary, making it subjective to categorize.

Does rapid heating of a catalyst increase ammonia slip?

Rapid heating of a catalyst, such as during a regeneration process, can significantly increase the amount of ammonia slip. In certain vehicles, an additional catalyst is installed downstream of the SCR catalyst to manage any excess ammonia. However, it is important to monitor the amount of DEF (diesel exhaust fluid) being used as there could be a potential issue with the dosing. If there is a strong ammonia smell in the exhaust, it is recommended to investigate further.
