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 are the pollutants that can be eliminated by improving the design of engines?
Hydrocarbons + Nitrogen Oxides + Carbon Dioxide + Carbon Monoxide
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 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 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
What kind of chemicals are cars smoke?
A car engines cumbustion cycle creates carbon monoxide(CO), hydrocarbons(HC), and nitrogen oxide(NOx). All 3 are dangerous and bad for the envirement, so a device called a "catalytic converter" chemicaly reacts with them and turns them into carbon dioxide(co2), water vapor(H2O), and nitrogen(N2). so to answer your question: CO2, H20, and N2.
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).
The hot expanding gases generated by the combustion reactions in the engines are?
released through the back of the engine to propel it and the airplane foward
What colorless poisonous has is a by-product of gasoline engines?
Carbon Monoxide.
What can fix nitrogen into oxides of nitrogen?
A common route to combine oxygen and nitrogen is in combustion engines such as industrial furnaces and automotive engines. this is due to the high temperatures and free oxygen and nitrogen gases in the system.
What fuel do you use for a catalytic converter?
Catalytic converters are used on most internal combustion engines as regulated by the EPA in the US. This would be any engine that runs on petroleum based fuels, or fules that emit nitrous oxide, carbon monoxide, and residual unburnt hydrocarbons.
What is the percentage of pollution that vehicles and engines contribute?
Nearly 70% of it is from cars. 20% is from Methane (from farting), and the rest from cloroforocarbons (or something like that) that used to be in the air back in the 70's (it was found in spray cans).
