"Research and Practice: Understanding Vehicle Energy" Chemical Reactions and Energy PPT

Part One: [Material Reading]

Material 1: History of automobile development

(1)Jet car:

In 1680, the famous British scientist Newton imagined a jet car, using a nozzle to inject steam to propel the car, but he failed to make it into reality.

(2) Steam-powered automobiles:

In 1769, Frenchman N.J. Guignaud built a three-wheeled vehicle driven by steam generated by burning gas.

In 1829, James of England invented a steam car with a speed of 25 kilometers per hour, which could be used as a large sedan.

(3)Gasoline cars:

1885 was the year of a decisive breakthrough in the invention of the automobile. German engineers Benz and Daimler, and British Butler respectively invented cars equipped with gasoline engines. Russian Puchlov and Volopov invented the automobile equipped with an internal combustion engine.

(4) Electric vehicles:

The first actually manufactured electric car was invented by American Anderson between 1832 and 1839.

In 1898, the German Porsche developed an electric car called "Lohner-Porsche", which used lead-acid batteries as its power source.

(5)Hyundai Motor:

In 1885, German engineer Karl Benz built a three-wheeled vehicle equipped with a gasoline engine in Mannheim. This car equipped with an internal combustion engine is considered to be the real first car in the world because it was the first car to be powered by gasoline instead of a steam engine.

(6) New energy vehicles:

①Hybrid vehicles: The internal combustion engine can work continuously, and the battery can be continuously charged, so its journey is the same as that of an ordinary car.

②Pure electric vehicles: Use batteries to provide electrical energy as power.

③Fuel cell vehicles: Use fuel cells to provide electrical energy as power.

④Hydrogen-powered vehicles

⑤Supercapacitor car

Material 2: Automobile fuel

1. Conventional automotive fuel

Gasoline and diesel are currently the most commonly used fuels for cars. Gasoline and diesel obtained through petroleum refining have high energy density, low price, are not easy to deteriorate, and are easy to transport, so they are very suitable for ignition engines and compression ignition engines.

2. Engine alternative fuel:

Engine alternative fuel refers to the use of alternative fuels instead of gasoline or diesel. Currently, alternative engine fuels developed and used in China include natural gas, liquefied petroleum gas, methanol, ethanol, biomass fuel, hydrogen and dimethyl ether.

Material 3: Fuel calorific value

Fuel calorific value, also called fuel calorific value, refers to the amount of energy released when the fuel per unit mass (referring to solid or liquid) or unit volume (referring to gas) is completely burned and the combustion products are cooled to the temperature before combustion (usually ambient temperature) heat.

Research and practice to understand vehicle energy PPT, the second part of the content: [Thinking about improvement]

1. Which fuel and energy conversion method did you finally choose? What factors did you consider when making your choice?

Tip: Choose hydrogen energy to convert chemical energy into electrical energy. When selecting, consider ① sources and reserves; ② impact on the environment; ③ price; ④ energy conversion efficiency.

2. What inspirations have you gained from understanding the development process of vehicle energy?

Tip: Gradually convert from traditional energy to clean, pollution-free, and recyclable new energy.
