Burning fossil fuel takes free oxygen from the air. In a car, air, which includes free oxygen, comes into the engine through an air filter and the air is then mixed with fuel and sent to the engine. The fuel-air mixture is ignited, gets hot, its pressure rises and this drives down a piston that drives the crankshaft.
The fuel contains carbon and hydrogen, and the burning process unites carbon with oxygen, and also hydrogen with oxygen. Both these chemical process produce a lot of heat.
The formation of these chemical bonds generates CO2 and H2O, also known as carbon dioxide and water, which are the major products of burning fossil fuel. In round numbers, burning 1 kg of fuel takes 3.5 kg of oxyen from the air, and generates 3.1 kg of CO2 plus 1.4 kg of water; and about 50 MJ of heat energy is generated.
In the average car engine, about 25% of the heat energy produced is converted into mechanical energy to drive the car.
What else can I help you with?
What are three technologies that burn fossil fuels?
things such as cars plans and certain factories burn fossil fuels
What are an advantige and disadvantige of energy reasourse for fossil fuels?
A disadvantage of fossil fuels is that when you burn them to create energy, it pollutes the air. An advantage of fossil fuels is that we use them to power cars and many other things.
How do cars effect the air quality from the fossil fuels?
Cars emit pollutants like carbon monoxide, nitrogen oxides, and particulate matter when burning fossil fuels. These pollutants can contribute to smog, respiratory issues, and global climate change. Transitioning to cleaner fuels or electric vehicles can help mitigate these impacts.
What fossil fuels do we burn in power stations?
they burn fossil fuels like coal, fuel oil, and oil shale
Do ecnomical cars use fossil fuels?
All cars use fossil fuels somewhere in their energy cycle.
Do fossil fuels burn?
Yes they do!
Do geothermal burn fossil fuels?
no
How do you make electrical current?
burn fossil fuels or turbines or hydro or wind
Do cars produce fossil fuels?
No. Most cars use fossil fuels (primarily gasoline and diesel made from oil).
Why does it matter if you burn fossil fuels?
When we burn fossil fuels, that fossil fuel is gone. *POOF!* And it'll take millions of years for the nonrenewable resource to form again. Therefore we need to conserve fossil fuels as much as possible.
How do they burn fossil fuels?
They set fire to them
How do we use fossil fuels for energy?
We burn them
