Diesel engine works by compressing air in the cylinder and injecting fuel at the right time to ignite the mixture.
Air is compressed in the cylinder by the piston
Fuel is injected into the cylinder at the right time
The heat generated by the compressed air ignites the fuel
The expanding gases push the piston down, creating power
Diesel engines are more efficient than gasoline engines
CC stands for carbon copy, a term used in email communication to indicate additional recipients of a message.
CC is used to send a copy of an email to someone other than the primary recipient
CC recipients are visible to all other recipients of the email
CC is often used for informational purposes or to keep others in the loop
CC can also be used to show transparency in communication
Compression ratio is the ratio of the volume of gas in a cylinder when the piston is at the bottom of its stroke to the volume of gas when the piston is at the top of its stroke.
It is a measure of how much the engine compresses the air/fuel mixture before ignition.
Higher compression ratios can lead to better fuel efficiency and more power.
Compression ratio is calculated by dividing the volume of the cylinder at bottom
Swept volume is the volume of space swept by a piston in an engine cylinder during one stroke.
It is the volume of the combustion chamber when the piston is at the bottom of its stroke subtracted from the volume of the combustion chamber when the piston is at the top of its stroke.
It is used to calculate the engine displacement.
For example, a four-cylinder engine with a 500cc swept volume has a total displacement of 2,0...

A diode is an electronic component that allows current to flow in only one direction. There are two types of transformers: step-up and step-down.
Diode is a semiconductor device that has two terminals and allows current to flow in only one direction
It is commonly used in rectifiers, voltage regulators, and signal limiters
Transformers are devices that transfer electrical energy from one circuit to another through electro...
Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.
Transformers work on the principle of electromagnetic induction
They consist of two coils, primary and secondary, wound around a magnetic core
When an alternating current flows through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil
The voltage in the secondary ...
Induction motor works on the principle of electromagnetic induction.
It has a stator and a rotor.
The stator has a set of windings that are connected to an AC power source.
The AC current in the stator windings creates a magnetic field that rotates around the stator.
This rotating magnetic field induces a current in the rotor windings, which in turn creates a magnetic field in the rotor.
The interaction between the stator a...
A rectifier is an electronic device that converts AC to DC voltage.
Rectifiers are used in power supplies to convert AC voltage to DC voltage.
They are commonly used in electronic devices such as radios, televisions, and computers.
There are two types of rectifiers: half-wave and full-wave.
The diagram of a rectifier typically shows a transformer, diodes, and a load resistor.
Rectifiers are important in ensuring that electr...
The function of the inverter is to convert DC power to AC power.
Inverters are commonly used in solar power systems to convert DC power from solar panels to AC power for use in homes and businesses.
Inverters can also be used in cars to convert DC power from the battery to AC power for charging devices.
There are two types of inverters: pure sine wave and modified sine wave, with pure sine wave being the more expensive an...
