Best Answer

Excess air in combustion helps ensure complete burning of fuel by providing enough oxygen for the reaction. This assists in maximizing energy output and reducing the formation of harmful emissions such as carbon monoxide. However, too much excess air can also lead to energy loss and inefficient combustion.

Why excess air is provided for combustion?

Excess air is provided for combustion to ensure that all fuel is completely burned, leading to higher combustion efficiency and lower production of harmful emissions. The additional air helps maintain proper mixing with the fuel, promoting a more stable and controlled combustion process.


Define mixture strength in combustion?

Mixture strength in combustion refers to the ratio of fuel to air present in the air-fuel mixture. It can impact the efficiency and performance of the combustion process, with a stoichiometric mixture (ideal ratio of fuel to air) typically providing optimal results. Adjusting the mixture strength can affect factors like power output, emissions, and fuel economy in combustion engines.


Does air support combustion?

Yes, air contains oxygen which is necessary for combustion to occur. When a fuel source is combined with oxygen in the air and ignited, combustion reactions release heat and light energy.


What device mixes air and petrol gas for the internal combustion engine?

The device that mixes air and petrol gas for an internal combustion engine is called a carburetor. It is responsible for blending the air and fuel in the correct ratio before delivering it to the engine for combustion.


What is always present for a combustion reaction to occur?

For a combustion reaction to occur, three things are required: fuel (such as gas or wood), oxygen (usually from the air), and a source of heat (spark or flame) to initiate the reaction. Without any of these three components, combustion cannot take place.

What is mix air heat and fuel?

A mixture of air, heat, and fuel is required for combustion to occur in internal combustion engines. The air provides oxygen necessary for the fuel to burn, while heat from sources such as spark plugs or compression ignites the fuel-air mixture. The combustion of the fuel generates energy that powers the engine.


What is minimum concentration of oxygen required for combustion?

The minimum concentration of oxygen required for combustion is typically around 16% in air. Below this level, the fuel will not be able to sustain a flame or combust.

Were is the carburetor on an ATV?

Usually, on top of the motor, under the gas tank and in front of the air cleaner. This is the typical location due to the fact that the job of the carburetor is to mix fuel and air to create spontaneous combustion required for an internal combustion engine to operate.


How can we reduce the combustion of fossil fuels?

You can change the air-to-fuel ratio to get less optimal combustion.


What is the air fuel ratio in petrol engine?

Ideally it is 14.7 air to 1 fuel in an internal combustion engine.

What are the total air volume supply requirements for an atmospheric burner?

The total air volume supply requirements for an atmospheric burner depend on factors such as the burner size, fuel type, and combustion efficiency. Typically, air volume is calculated based on the stoichiometric air-to-fuel ratio required for complete combustion. It is important to ensure that the correct amount of air is supplied to achieve optimal combustion and prevent issues such as inefficient burning or production of harmful emissions.
