Hydraulics (From Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids or fluids.

At a very basic level, hydraulics is the liquid version of pneumatics.

Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids.

In fluid power, hydraulics are used for the generation, control, and transmission of power by the use of pressurized liquids.

Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry, pumps.

The principles of hydraulics are in use naturally in the human body within the heart and the male erection.

Electric power quality, or simply power quality, involves voltage, frequency, and waveform.

Good power quality can be defined as a steady supply voltage that stays within the prescribed range, steady a.c.

frequency close to the rated value, and smooth voltage curve waveform (resembles a sine wave).

In general, it is useful to consider power quality as the compatibility between what comes out of an electric outlet and the load that is plugged into it.

The term is used to describe electric power that drives an electrical load and the load's ability to function properly.

Without the proper power, an electrical device (or load) may malfunction, fail prematurely or not operate at all.

There are many ways in which electric power can be of poor quality and many more causes of such poor quality power.

The fuel economy of an automobile is the fuel efficiency relationship between the distance traveled and the amount of fuel consumed by the vehicle.

Consumption can be expressed in terms of volume of fuel to travel a distance, or the distance travelled per unit volume of fuel consumed.

Since fuel consumption of vehicles is a significant factor in air pollution, and since importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy.

Different measurement cycles are used to approximate the actual performance of the vehicle.

The energy in fuel is required to overcome various losses (wind resistance, tire drag, and others) in propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning.

Various measures can be taken to reduce losses at each of the conversions between chemical energy in fuel and kinetic energy of the vehicle.

Driver behavior can affect fuel economy; maneuvers such as sudden acceleration and heavy braking waste energy.

In a motor vehicle, the term powertrain or powerplant describes the main components that generate power and deliver it to the road surface, water, or air.

This includes the engine, transmission, drive shafts, differentials, and the final drive (drive wheels, continuous track as in military tanks or caterpillar tractors, propeller, etc).

More recently in hybrid Powertrains the battery, the electric motor and the control algorithm are also seen as elements of the Powertrain.

Usually "powertrain" is used to refer to simply the engine and transmission, including the other components only if they are integral to the transmission.

The automotive industry is a wide range of companies and organizations involved in the design, development, manufacturing, marketing, and selling of motor vehicles, some of them are called automakers.
