The mechanical energy is made in the engine by burning fuel with oxygen to produce heat inside the cylinder, which makes hot gases at high pressure push a piston, and that turns the crankshaft.
The energy of the fuel is released by burning the carbon in the fuel to form chemical bonds with oxygen from the atmosphere (through the air filter) to form carbon dioxide (CO2). This is what produces the heat.
Hydrogen in the fuel also forms bonds with oxygen to produce water (H2O) in the form of steam, which also does work pushing the piston. So a gasoline or diesel engine is also partly a steam engine.
A typical vehicle engine is 20-25% efficient, that means that at least 75% of the chemical energy in the fuel is wasted.
Engineers know about this problem but it is not possible to increase the efficiency of a heat engine without using higher temperatures and pressures, which demands a more massive cylinder block and also makes the engine produce more harmful nitrogen compounds.
What else can I help you with?
What from of energy makes my car feel warm?
That is heat energy.
What energy form does a car engine transform from chemical energy?
Chemical energy transforms to kinetic energy which makes the car move.
What gasoline does to a car?
It provides the original source of energy that makes the car move. Gasoline has chemical energy, that is easily converted to thermal energy and then to mechanical energy(movement), which is used to propel the car.
How does the steam car work?
Like all engines the fuel makes energy which makes torqe then that pushes the car forward
Car or a fan spining sround has what type of energy?
A car converts the chemical energy in petrol to kinetic energy which makes it move along. A fan converts electrical energy into kinetic energy to make the blades turn.
What is it in the sun that makes a solar car go?
The sun's rays are converted into energy
A car moves how?
You turn the key, the car has energy from the petrol that makes the wheels move, this movement turns the tires and then the car moves, slowly at first but then it makes a move by using the petrol. This is CO2.
What makes the battery operated toy car moved?
Because is a one of energy's sources
What are energy transformation of remote toy car?
A remote toy car primarily transforms electrical energy from its batteries into mechanical energy to drive its motors, enabling movement. Additionally, some energy may be converted into sound energy when the car makes noise and thermal energy due to friction in the moving parts. Lastly, light energy can be produced if the car features headlights or decorative lights. Overall, these transformations allow the car to operate and enhance the user experience.
How does a pull back car work and what makes it move forward when pulled back?
A pull back car works by storing energy when it is pulled back and then releasing it to move forward. When the car is pulled back, a spring inside the car is compressed, storing potential energy. When the car is released, the spring expands, releasing the stored energy and propelling the car forward.
What makes a electric car move?
The electric car moves because the batteries power the motor. The motor then turns the electricity into mechanical energy. The mechanical energy is then transfered to the wheels through the drive train.
When does gasoline gives off energy?
gasoline is a fuel. It produces energy when the fuel is burned. In your car the spark makes tiny explosions which drive engine pistons up and down, thus moving your car.
