A 4-cycle engine will mix gasoline with air during the intake stroke at aprox 14.7 (air) to 1 (gasoline) ratio.
Gasoline and diesel are two common types of fuel that use combustion to produce energy. During combustion, these fuels react with oxygen to release heat energy that powers engines.
When gasoline is burned, it reacts with oxygen to produce carbon dioxide, water vapor, heat, and light. This process is known as combustion. The heat and light energy released during combustion is what powers car engines and provides energy for other applications.
When gasoline burns with oxygen during combustion, carbon dioxide and water vapor are formed as the main byproducts of the reaction.
During the combustion of gasoline in a car engine, the chemical energy stored in gasoline is converted into thermal energy through combustion. This thermal energy is then used to power the engine and drive the vehicle. While there may be some energy lost as heat or sound during combustion, the total energy of the system (including the car, gasoline, and surroundings) remains constant, thus conserving the energy of the universe.
Fuels like gasoline, diesel, natural gas, and coal are commonly used in combustion engines to produce energy. During combustion, these fuels react with oxygen to release heat and generate power for various applications such as transportation and electricity generation.
Engine performance and efficiency is measured not only on how it was constructed and the materials used, but also on the characteristics of the fuel it will use. For gasoline fed engines, the smaller the molecules, the better the power is produced during combustion. Different Oil companies have their own blends for gasoline and the particle sizes will range from 30 to 100 microns depending on the blend. Engine designers have introduced advanced injection systems that further break down the gasoline particles up 10 microns as they are fed into the combustion chamber.
Development of the internal combustion engine
development of the internal combustion engine.
Yes. During WWII some fighter planes engines had the capability to inject small quantity of ethanol inside the cylinders to increase the octane rating of the gasoline. The higher the octane rating the better the more compression a fuel can withstand before detonating. It is a way to augment thrust in IC engines. (although to my knowledge not so widely used in present days)
The development of the internal combustion engine
Yes, the combustion of gasoline in a car engine is a chemical change. During combustion, gasoline reacts with oxygen to produce carbon dioxide, water, and energy, which are all different substances from the original gasoline.
