The main differences between internal combustion engines and electric motors and their respective ad

Main differences: 1. The concept is different.

An electric motor is an electrical device (electricity), which is a device that converts electrical energy into mechanical energy.

An internal combustion engine is a device that generates electricity (power generation) and converts other forms of energy into mechanical energy.

2. The principle is different.

The internal combustion engine usually converts chemical energy into mechanical energy, and the internal combustion engine is applied to both the power generation unit and the entire machine including the power unit.

An electric motor is a prime mover powered by electricity, provided that there must be electricity first. Electrical energy becomes mechanical energy, there are two types of motors, AC and DC, which can rotate under the action of electromagnetic force and drive the driven machinery to rotate and work after being connected to the power supply.

Pros and cons:

Save energy. In the case of the car itself, the efficiency of electric motors and high-voltage transmission is much higher than that of internal combustion engines. Gas and steam turbines used for power generation are more efficient than gasoline engines, making them more energy-efficient and cost-effective.

At present, the power consumption of mainstream electric vehicles on the market is less than 20 kWh per 100 kilometers. In this way, the power consumption is much lower than that of gasoline vehicles of the same class.

Low pollution. Compared with the large amount of nitrogen oxides and sulfur dioxide produced by gasoline vehicles, electric vehicles can be said to have completely zero pollution. The only pollution is generated during the power generation process, but this can be treated centrally at the power plant, resulting in less harm and better driving quality.

The electric motor is much less noisy than gasoline and diesel engines, so it is quieter to ride.

The internal combustion engine converts chemical energy into mechanical energy, while the electric motor converts electrical energy into mechanical energy, and the working principle is different. The internal combustion engine needs to burn fuel, which is relatively large, exhaust gases, pollute the environment, and is very noisy, but its fuel is easy to carry, used in transportation, and can carry enough fuel to travel long distances. The motor is small in size, does not pollute the environment, does not exhaust exhaust gases, and the noise is also very small, but it needs electric energy to work, and the electric energy is not easy to carry, unless it is to carry a battery, and the capacity of the battery is limited, so the driving distance is limited.

If it is used in a fixed situation, a motor can be used, which is relatively suitable.

Take the train as an example:

Electric locomotives are more powerful and more powerful. It is easier to achieve automatic control. Especially in areas with large changes in slope, more carriages can be towed. And you don't have to carry a lot of fuel with the car. Its disadvantage is that it needs to build a complete set of power supply and transformation facilities.

The modern distributed power system, the EMU, is dragged by an electric motor. It should be pointed out that high-speed trains must use this technology.

Summary. From the moment the first ignition of an internal combustion engine car starts, various structures begin to wear out. Therefore, various parts and consumables, including engine oil, must be replaced every time they are driven.

And what about electric cars? Given that their structure is different from that of internal combustion engine vehicles, there are worlds of difference in some places and not much in others. Electric vehicles do not have engines and transmissions, and the maintenance burden is lower than that of internal combustion engine vehicles.

Electric cars are very different from internal combustion engine vehicles equipped with engines. Unlike internal combustion engine vehicles, which are powered by burning fossil fuels, electric vehicles rely on electricity stored in batteries to drive electric motors to spin. Because of this difference, driving an electric car is very different than ever.

Unlike internal combustion engine vehicles, there is no need to worry about it.

Can you be more concise and clear?

It's that pure electric vehicles don't have a fuel system.

The electric motor is driven by electricity, smaller than the internal combustion engine, and the structure is not the same, the motor has armature winding, brush, excitation winding, commutator, etc., the internal combustion is driven by burning gasoline or diesel, and is composed of cylinder heads, valve seats, intake and exhaust pipes, pistons, crankshafts, camshafts, etc., and the internal combustion engine is driven by the electric motor.

An electric motor is a point-powered prime mover, provided that there must be electricity first. Electrical energy becomes mechanical energy. The electric motor is a passive equipment for the purpose of generating electricity, which is generally converted into electrical energy by mechanical energy such as wind, water conservancy and manpower through coils and magnetic field changes, and is a device that manufactures electricity.

Engines generally include internal combustion engines, steam engines, etc., which mainly convert the chemical energy in gasoline and diesel fuels into mechanical energy. Applications The engine can be used to drive the generator to generate electricity, and the electricity is driving the electric motor to generate mechanical energy.

There is a difference, an internal combustion engine is a machine that converts internal energy into mechanical energy, whereas a generator is a machine that converts mechanical energy into electrical energy.

The internal combustion engine is the power, the generator is the electricity, and the generator is driven by the power to generate electricity.

The internal combustion engine converts the chemical energy of fuel combustion into internal energy, and then converts the internal energy into mechanical energy. Whereas, a generator is a machine that converts mechanical energy into electrical energy.

There are many kinds of internal combustion engines, such as gasoline engines and diesel engines in automobiles.

Of course, you may have to ask, is the diesel generator an internal combustion engine or a generator? In fact, we may understand diesel generators as a combination of internal combustion engine and generator. First, the combustion fuel of the internal combustion engine is converted into internal energy, and the internal energy is converted into mechanical energy, and the mechanical energy is converted into electrical energy by driving the magnetic inductance line of the coil cutting machine of the generator.

To sum up: an internal combustion engine is not a generator, but it can drive a generator to generate electricity.

Diesel generator is a compression-ignition internal combustion engine made of diesel, which is composed of three parts, such as a three-phase AC synchronous generator and a control system.

Diesel generator is an internal combustion engine that uses the high temperature and high pressure generated by the compression of air in the cylinder to spontaneously combust the diesel fuel injected into the cylinder and expand for work. It has the advantages of compact structure, reliable use, excellent technical indicators such as power and economy, rapid starting, simple operation and convenient maintenance.

The internal combustion engine is: chemical energy is converted into thermal energy, and thermal energy is converted into mechanical energy.

Generators are: mechanical energy is converted into electrical energy.

No, it can generate electricity, but it's not!

It seems that the internal combustion engine can be used as the prime mover of the generator.

The internal combustion engine is a high-pressure combustion chamber directly fed into the cylinder after mixing liquid or gaseous fuel with air, and the combustion burst generates power. It is also a heat engine that converts thermal energy into mechanical energy. The internal combustion engine has the characteristics of small size, small mass, easy to move, high thermal efficiency and good starting performance.

However, internal combustion engines generally use petroleum fuels, and the exhaust gas discharged from the key is high in harmful gases. (For a detailed introduction to the internal combustion engine, please see the encyclopedia information) (Yanan Group: R & D and production of diesel generator sets and fuel cells).

Generators are mechanical devices that convert other forms of energy into electrical energy, which are driven by water turbines, steam turbines, diesel engines or other power machinery to convert the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transfer it to the generator, which then converts it into electrical energy. Generators have a wide range of uses in industrial and agricultural production, national defense, science and technology, and daily life.

Friends must also understand the working principle of the generator after reading this popular introduction. Then it is in our diesel generator set is to convert the power generated by the diesel engine into electricity output to our users. (For more information about the generator, please go to the encyclopedia).

Then after understanding the basic concepts of internal combustion engine and generator, it should not be difficult to understand the difference between them, they are actually a system. The internal combustion engine generates movement through fuel, and this movement drives the generator to move through other transmission equipment such as bearings or pulleys, and then sends a physical action between the magnetic inductance coil inside the motor and the permanent magnetic field to generate electricity, and then transmits the electricity to the user through the cable.

Yes, if someone specifically says something, I won't say it.
