Fuel oil used by most plant machinery.

Rudolf Diesel

The fuel gets its name from Rudolf Diesel, the man who produced the first compression ignition engine whilst working for MAN in Augsburg, Germany, in 1897.

Check here for more information on how diesel engines work.

:

This is the unit of electrical force that pushes electrons around a circuit. This force can be small, as in the case of plant vehicles-12 volt or 24 volt, or it can be large, as in the mains electricity in a workshops-110 volt, 220 volt or 380 volt.

This is a measure of the resistance in an electrical circuit, and it is measured in ohms.

The Greek letter Omega, Ω, is often used to represent resistance in electrical circuits.

To boot a computer means to switch it on and allow the loading of the operating system. When the operating system (OS) is loaded and running, the user can take control of the machine.
:
The operating system (os) of a computer is the system that runs the computer and makes all the software and programs installed on it available to you, the user. In the CP computer room, the operating system is Windows 2000. Other examples of operating systems are Linux, Windows XP, Windows 98.

There are at least 2 different contexts where we use the word "burn" on the phase 2 cp course.

When used in the context of engines and combustion, we speak of how we burn fuel. Fuels used in plant machinery contain engrgy. In order to release that energy so that we can do some work with it, we burn the fuel. As the fuel burns, its energy is converted from chemical energy to heat energy.
Heat energy acts on the crown of the piston, forcing it down the cylinder and turning the crankshaft.
This converts the heat energy into mechanical energy. We transmit this energy through the gearbox and drive shaft to the road wheels or tracks, thus moving the vehicle. The burning process is initiated in two main ways in engines: In a petrol engine, a spark plug is used, and in a diesel engine, air is compressed so much that it becomes very hot. Into this hot air, we inject atomised fuel, which after a short delay period, begins to burn, thus releasing its energy.

When used in the context of computers, to "burn" a CD-R (Compact Disc-Recordable) is to write information to the disc by means of a low-intensity laser, which "burns" the digital information onto the disc.

:
The toggle key on a keyboard that, when selected, changes the alphabetical keys on the keyboard from lower case to capital letters.
:

An acronym based on a German phrase, Deutesches Institut fur Normung, or the German Institute for Standards.

:

Acronym for Department of Transportation, an American standard. An example of use is "DOT 5 Brake Fluid".

:

Energy is the ability to do work.
Because work is measured by multiplying the force applied by the distance moved, energy is measured in Nm or Joules.
1 Joule = 1 Newton metre. Symbol: J or Nm

If one joule of energy is expended in 1 second, one watt of power is said to have been expended.

There are many different types of energy. Some examples are:

Wind energy, solar energy, nuclear energy, electrical energy, potential engery.
