What is incomplete combustion?

Answer 1

• Reaction or process that does not convert all of the fuel's carbon and hydrogen into carbon dioxide and water, respectively. For example, incomplete combustion of carbon produces carbon monoxide.
• It is also a flame, but this flame is a jellow one so is not as harmfull

However none of these answers will help with your homework when you are in year 7.

Answer 2

Incomplete combustion occurs when a fuel does not burn completely, resulting in the production of byproducts like carbon monoxide, particulate matter, and unburned hydrocarbons. This can happen when there is insufficient oxygen present during combustion. Incomplete combustion can lead to reduced efficiency, increased emissions, and pose health and environmental risks.

Answer 3

incomplete combustion- Reaction or process that does not convert all of the fuel's carbon and hydrogen into carbon dioxide and water, respectively. For example, incomplete combustion of carbon produces carbon monoxide.

complete combustion-whatever you are burning (usually hydrocarbon) burns/reacts completely with oxygen gas (O2) to form ONLY CO2 (carbon dioxide) and water (H2O).

Answer 4

Total combustion or perfect combustion is the result of a proper air to fuel ratio mixed with the proper amount of heat in an engine.

Let me explain.

In an internal combustion engine there are 3 things that produce power in an engine.

• Air
• Fuel
• Heat

When the proper amount of air is mixed with fuel (14.7 parts of air to 1 part of fuel) and met with an adequate heat or ignition source (spark from spark plug), you theoretically should achieve total combustion. In a gasoline engine you get air and fuel mixed together in its proper ratio, and have it enter one of the engines cylinders. When the piston within the cylinder is in its upward compression stroke, the compression creates pressure and which heats up the mixture. The spark plug then fires slightly before the piston reaches top dead center (normally 12 degrees before) and causes the air mixed with the fuel to ignited. This is known as combustion. The perfect combustion results should be H2O, CO2 and heat (Water, Carbon Dioxide, and Heat).

It has yet to be achieved by engineers, and the result being less than perfect emissions. This is why we have emission control systems in place such as Catalytic Converters to reduce all the harmful gases. These pollutants include Hydro Carbons, Carbon Oxide, and Oxides of Nitrogen. (HC, CO, NOx)

Answer 5

It means that whatever you are burning (usually hydrocarbon) burns/reacts completely with oxygen gas (O2) to form ONLY CO2 (carbon dioxide) and water (H2O).

So that means there are no by-products!

Only CO2 and H2O are your products.

Answer 6

Complete combustion is when a hydrocarbon fully oxidises and produces carbon dioxide and water.

Answer 7

Complete combustion occurs when the carbon and the oxygen are in perfect combination to completely burn the fuel. This may also be known as zero excess air combustion.

Answer 8

Complete combustion

fuel + oxygen = water + carbon dioxide

Incomplete combustion

fuel + oxygen = water +carbon dioxide + soot (carbon)

Answer 9

To have a sufficient quantity of oxygen.
