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 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 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 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.
What harmful gases come from a jet?
Jet engines emit several harmful gases, primarily carbon dioxide (CO2), nitrogen oxides (NOx), and water vapor. CO2 contributes to greenhouse gas emissions and climate change, while NOx can lead to the formation of ground-level ozone, which is a significant air pollutant. Additionally, jet engines produce particulate matter and unburned hydrocarbons, which can adversely affect air quality and human health.
State the two main exhaust gas pollutants generated by a compression ignition diesel engine?
The two main exhaust gas pollutants generated by a compression ignition diesel engine are nitrogen oxides (NOx) and particulate matter (PM). NOx is formed during high-temperature combustion, contributing to smog and acid rain, while particulate matter consists of tiny soot particles that can harm respiratory health and the environment. Additionally, unburned hydrocarbons and carbon monoxide can also be present but are typically considered secondary pollutants in diesel engines.
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 gas is formed when octane is burned in engines?
When octane (C8H18) is burned in engines, it primarily produces carbon dioxide (CO2) and water vapor (H2O) through the combustion process. However, incomplete combustion can also generate carbon monoxide (CO) and various hydrocarbons, along with nitrogen oxides (NOx) due to the high temperatures in the engine. The overall reaction highlights the environmental impact of burning fossil fuels, contributing to greenhouse gas emissions and air pollution.
