Types of Energy Conversion Machines

Types of Energy Conversion Machines - Machines are machines that produce motion/work. From the description above, it can be concluded that an energy converter machine is a tool that converts one energy into another energy so that it will produce a job/business that is utilized for the benefit of humans.

Types of Energy Conversion Machine

There are various types of energy conversion machines that we can use in everyday life, especially in the automotive field. Here are some energy conversion machines, including:

1. Combustion Engine

Is a mechanism / construction that converts heat energy into motion / mechanical energy. The heat energy from burning fuel in the energy conversion system will produce mechanical energy in the form of a push or pressure to the piston which is passed through the connecting rod to the crankshaft so that there will be rotational movement on the crankshaft.

The following types of combustion engines are seen from how to obtain heat energy:

a. Internal Combustion Engine

An internal combustion engine is an engine in which the fuel combustion process occurs inside the engine itself and the heat from the combustion is directly converted into motion energy by a direct system. Examples: gasoline engines, diesel engines, jet engines, and others - others.

b. External Combustion Engine

External combustion engine is a motor whose fuel combustion process occurs outside the engine itself, so that in carrying out combustion a separate engine is needed, and the heat from the combustion of fuel is not directly converted into motion energy. but through a transmission medium to be converted into energy movement Examples: steam engines, steam turbines, and others.

2. Compressor

Compressor is a device for compressing air and compressing air and producing compressed air for certain needs. Because the compression process occurs, it has a higher air pressure than the surrounding air.

The working mechanism of the compressor is that free air is sucked in by the piston in the compressor through the downward movement of the piston from TDC to BDC (called the suction stroke). Then the piston pushes the air that has been sucked into the air storage tube through the valve mechanism, the incoming air is stored in the storage tube. The movement of the piston because the crankshaft is connected to the pulley, the pulley is connected to the electric motor for the electric compressor and connected to the gasoline motor for the gasoline compressor and compressed air in the storage tube is used according to the needs of the system used.

Example: Pneumatic system, wind brake, and others.

3. Electric Motor

An electric motor is an electromagnetic device that converts electrical energy into mechanical energy which is used to rotate pumps, turn fans, operate compressors, lift materials, rotate blowers, and so on.

While the electromagnet is a magnetic field generated by the flow of electric current in a conductor or coil.

The working principle of an electric motor is according to Fleming's law (left hand rule). Where the index finger is a symbol of the direction of the magnetic field; The middle finger as a symbol of the direction of current in the conductor, and the thumb as a symbol of the direction of the magnetic force on the conductor.

4. Gas Turbine

A device that utilizes gas as a fluid to rotate a turbine with internal combustion. In a gas turbine, kinetic energy is converted into mechanical energy by compressed air which rotates the turbine wheel to generate power.

The simplest turbine system consists of a compressor, combustion chamber and turbine. The working principle in brief is that the air enters the compressor through the air inlet. The compressor works to suck up and increase the air pressure so that the air temperature also increases, before entering the combustion chamber.

Combustion occurs in the combustion chamber due to the presence of compressed air with fuel, the process takes place at constant pressure and the combustion chamber only raises the temperature.

The combustion gas is flowed to the gas turbine through a nozzle which functions to direct the flow to the turbine blades. The power generated by the gas turbine is used to rotate the compressor itself and other loads such as electric generators and others. The exhaust gases from the work will continue to exit through the exhaust duct.

5. Cooler

This machine is generally used in air conditioning a room to feel comfortable as desired. This machine is commonly referred to as AC or AC, where AC is a vital need for both heavy vehicles, light vehicles, and households.

6. Solar Cell

Solar cell is a device used to convert solar thermal energy into electrical energy and then the electrical energy is used as needed.

That's the discussion this time about the types of energy conversion machines and their types. Hopefully it can be useful.
