What do cars with petrol engines have in their exhaust system to reduce the amount of carbon monoxide unburned hydrocarbons and nitrogen oxides in their exhaust gases?
The catalytic converter reduces carbon monoxide, as well as unburned hydrocarbons.
The EGR system introduces exhaust gas to the intake, creating a lower combustion temperature, and in turn less oxides of nitrogen.
There are more advanced systems on newer cars, but these are the basics.

What else can I help you with?
What are the pollutants that can be eliminated by improving the design of engines?
Hydrocarbons + Nitrogen Oxides + Carbon Dioxide + Carbon Monoxide
What pollutants does car engine produce?
Car engines produce several pollutants, including carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), and particulate matter (PM). Carbon monoxide is a toxic gas formed from incomplete combustion, while nitrogen oxides contribute to smog and acid rain. Hydrocarbons, which include unburned fuel, can lead to ground-level ozone formation. Particulate matter consists of tiny particles that can harm respiratory health and contribute to environmental degradation.
What is the name of the compound that makes up the other gases in exhaust from petrol engines?
The majority is N2 since air is 78% of the other gasses in the exhaust from petrol engines. Hydrogen forms water H2O, which depending on the combustions of the engine.
Do cars emit Chloroflorocarbons?
Internal combustion engines don't emit cloroflorocarbons, but they do emit hydrocarbon's. Hydrocarbons are/is unburned fuel which can be caused by a number of things,but it all leads back to unburned fuel.
What gas comes out the exhaust pipe of a car and is a result of combustion?
The major gas that comes out of cars (internal combustion engines) is carbon dioxide. There are many other gases as well, such as carbon monoxide, nitrous oxides, water vapor, and unburned gasoline.AnswerGas % of the gas in the exhaust fumesCarbon Dioxide 9%Carbon Monoxide 5%Oxygen 4%Hydrogen 2%Hydrocarbons 0.2%Nitrogen Oxides 0.2%Sulfur Dioxide less than 0.003%Lead (I think) 79.6%
What is unburned fuel?
Unburned fuel refers to the portion of fuel that does not undergo complete combustion during a fuel-burning process, such as in internal combustion engines or industrial burners. This can occur due to inefficient combustion conditions, improper air-fuel mixture, or equipment malfunctions. Unburned fuel can contribute to environmental pollution, producing harmful emissions like hydrocarbons and carbon monoxide, and can also lead to reduced engine efficiency. Reducing unburned fuel is essential for improving energy efficiency and minimizing environmental impact.
What are the waste byproducts of internal combustion engines?
The waste byproducts of internal combustion engines primarily include carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons, and particulate matter. During the combustion of fuel, these substances are released into the atmosphere, contributing to air pollution and climate change. Additionally, unburned fuel and oil can also be emitted, leading to further environmental concerns. Proper emission control technologies are essential to mitigate these harmful byproducts.
What colorless oderless poisonous gas is a by-product of gasoline engines?
Carbon monoxide (CO) is found in the exhaust of gasoline engines.
What is the purpose on an exhaust emission system?
The purpose of an exhaust emission system is to reduce harmful pollutants produced by internal combustion engines before they are released into the atmosphere. This system captures and transforms toxic gases, such as carbon monoxide, nitrogen oxides, and unburned hydrocarbons, into less harmful substances through various components like catalytic converters and exhaust gas recirculation. By minimizing emissions, the system helps to comply with environmental regulations and improve air quality, contributing to public health and environmental protection.
What is the exhaust gas composition of internal combustion engines?
3 major gasses (as checked in an emission test) hydrocarbons, Co. & Nox (oxides of nitrogen) In exhaust gas of diesel engines (at correct fuel mixture) there was 13.8% CO2 (carbon dioxide) and 84.5% N2 (nitrogen).
What is the name of the compound NO?
Nitric oxide or nitrogen monoxide is a chemical compound with chemical formula NO. This gas is an important signaling molecule in the body of mammals, including humans, and is an extremely important intermediate in the chemical industry. It is also a toxic air pollutant produced by cigarette smoke automobile engines and power plants.Source: http://en.wikipedia.org/wiki/Nitric_oxide
Do diesel engines produce carbon monoxide?
Yes, diesel engines produce carbon monoxide as a byproduct of combustion.
