Question

Електричні двигуни мають низку переваг перед тепловими.Чому ж людство не відмовляється від застосування теплових двигунів?

Answer 1

Дешевше виходить працювати на вже готовому матеріалі, ніж розробляти новий. Тому що електроенергія в чистому вигляді в природі не існує, і її, електроенергію, потрібно добути. А теплова енергія - ось вона, будь ласка: спалив паливо, визволив його теплоту згоряння і перетворив теплову енергію в електроенергію.

Electric Motors vs. Internal Combustion Engines

Electric motors have several advantages over internal combustion engines. Some of these advantages include:

1. Efficiency: Electric motors are generally more efficient than internal combustion engines. They convert a higher percentage of the energy they consume into useful work, while internal combustion engines waste a significant amount of energy as heat.

2. Environmental Impact: Electric motors produce zero tailpipe emissions, making them more environmentally friendly compared to internal combustion engines. This is especially important in reducing air pollution and combating climate change.

3. Lower Operating Costs: Electric motors have lower operating costs compared to internal combustion engines. They require less maintenance, have fewer moving parts, and do not require oil changes or regular tune-ups.

4. Quiet Operation: Electric motors operate silently, providing a quieter and more comfortable experience for both drivers and passengers. This is in contrast to the noise and vibrations produced by internal combustion engines.

5. Instant Torque: Electric motors deliver instant torque, providing quick acceleration and responsive performance. This is particularly advantageous in stop-and-go traffic and for electric vehicles.

Despite these advantages, there are several reasons why humanity has not completely abandoned the use of internal combustion engines. These reasons include:

1. Infrastructure: The infrastructure for electric vehicles, such as charging stations, is still developing and not as widespread as gasoline stations. This lack of infrastructure makes it less convenient for people to switch to electric vehicles.

2. Range Anxiety: Electric vehicles typically have a limited range compared to vehicles with internal combustion engines. This can cause range anxiety, the fear of running out of battery power before reaching a charging station. Although the range of electric vehicles is improving, it is still a concern for some people.

3. Cost: Electric vehicles are generally more expensive than vehicles with internal combustion engines. The cost of batteries, which are a significant component of electric vehicles, contributes to the higher price. While the cost of electric vehicles is decreasing over time, it remains a barrier for some consumers.

4. Energy Storage: The energy density of batteries used in electric vehicles is still lower compared to the energy density of gasoline or diesel fuel used in internal combustion engines. This means that electric vehicles may require larger and heavier batteries to achieve the same range as vehicles with internal combustion engines.

5. Legacy Infrastructure: The existing infrastructure for gasoline and diesel fuel, such as refineries and distribution networks, has been developed over many years. Transitioning away from internal combustion engines would require significant changes to this infrastructure, which can be costly and time-consuming.

It is important to note that the adoption of electric motors is increasing, and many countries and companies are investing in the development of electric vehicles and charging infrastructure. As technology advances and the advantages of electric motors become more pronounced, the transition away from internal combustion engines is expected to accelerate.
