 A turbocharger, or turbo, is a gas compressor that's used for forced-induction of an internal piston engine. A kind of supercharger, the point of a turbocharger is to extend the density of air entering the engine to form more power. a turbocharger has the compressor powered by a turbine, driven by the engine's own exhaust gases, instead of direct mechanical drive as with plenty of other superchargers.
Nomenclature
Early makers of turbochargers referred to them as "turbosuperchargers". A supercharger is an air compressor used for forced induction of an engine. Logically then, adding a turbine to turn the supercharger would yield a "turbosupercharger". the term was shortly shortened to "turbocharger". This is now a source of bewilderment, as the term "turbosupercharged" is often used to refer to an engine that uses both a crankshaft-driven supercharger and an exhaust-driven turbocharger. Some companies like Teledyne Continental Motors still use the term turbosupercharger in its original sense.

A turbosteamer is a term utilized by BMW to explain a mixed cycle engine. It involves the use of a steam engine to convert waste heat power from a combustion engine into supplemental power for the automobile. The turbosteamer device is joined to the exhaust system. It salvages the heat wasted at the exhaust ( as much as eighty percent of heat energy ) and uses a steam piston to relay that power to the crankshaft. The steam circuit produces fourteen h.p. ( ten kW ) and fifteen foot-pounds force ( 20 Nm ) of torque at top ( for a 1.8 Straight-4 engine ), yielding a projected 15% gain in fuel potency. Unlike gas-electric hybrids, these gains increase at topper, steadier speeds.

A regenerative brake is an energy recovery mechanism that decreases automobile speed by changing some of its kinetic energy into a handy sort of power rather than abating it as heat as with a standard brake. The converted kinetic energy is stored for later use or fed back into a power system to be used by other cars. Electric regenerative brakes in electrical railway automobiles feed the generated electricity into the supply system.
In battery electrical and cross-breed electrical automobiles the energy is kept in a battery or bank of capacitors for later use. Energy might also be stored by compacting air or by a revolving flywheel. Regenerative braking isn't the same as dynamic braking, which disperses the electric energy as heat and doesn't maintain energy in a serviceable form.

 Computational fluid dynamics is one of the branches of liquid mechanics that uses numeric techniques and algorithms to unravel and analyze issues that involve liquid flows. PCs are used to perform the millions of calculations needed to simulate the interaction of liquids and gases with surfaces outlined by boundary conditions. Even with high speed supercomputers only approximate solutions can be accomplished in numerous cases. Continuing research may yield software that improves the accuracy and speed of complicated simulation eventualities like transonic or turbulent flows. First endorsement of such software is usually performed employing a wind tunnel with the last validation coming in flight test.
