stoichiometric air fuel

An internal combustion engine works with a system of pistons. A mixture of air and petrol vapor, is drawn from the carburetor into the cylinder in the down-stroke of the piston. In the upstroke phase, the mixture is compressed. The ratio of the initial volume to final volume is called th..

Pollution caused due to Combustion of Fossil Fuels - With Man's ever increasing need for energy, he has been using fossil fuels indiscriminately. In the process, harmful materials contributing to air pollution are being produc..

At normal temperature, fuels are stable even in the presence of air. This is because, the activation energy of combustion reaction is high. When a mixture of fuel and air is burned, a flame has to be applied, that is the mixture has to be ignited. Near ..

The stocks of fuels are limited and hence use of energy saving devices is a must. As far as possible use only renewable sources of energy. More efficient heating installations should be employed while cooking. Incomplete combustion of fuel results in wastage of fuel le..

Fuels such as coal, petroleum and natural gas, which undergo combustion (burnt in air either alone or after mixing with another substance) and release energy are needed for the working of machines. The energy released keeps the machines working. More is the energy released, bet..

(Molar mass of CH 4 =16) The fuels are graded, and priced on the basis of their calorific values. Amongst the fuels, hydrogen has the highest calorific value. But, hydrogen is not used as the domestic/industrial fuel because of the following reasons: Hydrogen has a ver..

With Man's ever increasing need for energy, he has been using fossil fuels indiscriminately. In the process, harmful materials contributing to air pollution are being produc..

Contamination of air with harmful toxic gases, smoke and particulate matter (e.g., dust etc.) is called air pollution. The substances that cause pollution are called pollutants. Combustion of fossil fuels is one of the main causes of pollution of the atmosphere i..

Air pollution can be controlled by different methods depending on the source and the pollutant. The different methods are: One of the major causes of air pollution are the automobiles. The fuels being used should be lead-free as this will reduce the level of lead in th..

>Oxygen is present 21% by volume in air. It supports life and combustion. It is added to air by photosynthesis and removed from air by respiration and combustion. Nitrogen is present 78% by volume in air. It is present in proteins, which are essential for lif..
