<onlyinclude>'''''Energy Education''''' has plenty of pages to help one understand the workings of their '''motor vehicle'''. This page provides a starting point for anyone keen on learning more about cars to pick and choose what interests them.</onlyinclude> Worldwide, vehicles use ''a lot'' of [[energy]] - visit [[transportation energy use]] for more information.

==Types of automobiles==

*[[Internal combustion engine|Internal combustion vehicle]]s (most common type worldwide)
*[[Hybrid car]]s
*[[Electric vehicle]]s

==What powers a vehicle?==
[[File:4StrokeEngine.gif|thumb|300px|right|Figure 1. 4-stroke internal combustion engine. 1:fuel injection, 2:ignition, 3:expansion(work is done), 4:exhaust.<ref>Wikimedia Commons [Online], Available: https://upload.wikimedia.org/wikipedia/commons/d/dc/4StrokeEngine_Ortho_3D_Small.gif</ref>]]
Most vehicles around the world rely on [[hydrocarbon combustion]] of [[fossil fuel]]s in order to provide [[power]] to the rest of the vehicle. Newer technologies allow the use of [[battery|batteries]] to power the vehicle. The following pages discuss this process in more detail.

===Energy source / Engine type===
*[[Gasoline]] / [[Gasoline engine]]
*[[Diesel]] / [[Diesel engine]]
*[[Electricity]] / [[Electric motor]]
*[[Hydrogen as an energy currency|Hydrogen]] / [[Fuel cell]]

===Specific engine designs===
*[[Reciprocating engine]]
*[[Stirling engine]]
*[[Rotary engine]]

In order to provide [[ignition]], gasoline engines use '''[[spark plug]]s''' which transform low battery [[voltage]] into extremely high voltages in order to provide a spark to the gasoline. Diesel engines use a different technique to do so, as they rely on compression to provide enough [[pressure]] to ignite its fuel.

==Car parts and power distribution==
:''see also: [[drive train]]''
Once energy is transformed from its chemical state contained in the [[fuel]], there are various parts designed to deliver this energy to the wheels.

*'''[[Engine block]]''' is the strong casing for the engine's cylinders which case the pistons and spark plugs.

*'''[[Piston]]s''' contain the working fuel, and expand from increased pressures inside their chamber. This expansion provides [[work]] to the next component.

*'''[[Crankshaft]]''' is connected directly to the pistons, and transforms their linear motion into [[rotational energy]].

*'''[[Transmission]]''' consists of a series of [[gear]]s, which are rotated by the crankshaft. The driver can select these gears with the selector fork in a manual transmission vehicle to determine the amount of [[torque]] to be delivered to the next component.

*'''[[Drive shaft]]''' is a rotating shaft that delivers the power from the transmission to the wheels.

*'''[[Differential]]''' is a network of gears that deliver the final power to the wheels. This part allows for the wheels to rotate at different speeds, useful for turning around corners, or providing uneven torque to individual wheels whenever needed.

Visible parts include the transmission (silver box), drive shaft (long bar in the middle), differential (between the far back tires) and more.<Ref>Wikimedia Commons [Online], Available: https://upload.wikimedia.org/wikipedia/commons/f/fb/Subaru_Liberty_powertrain_%282010-10-16%29.jpg</ref>]]

==Energy recovery==
In certain vehicles it is practical to recover some of the vehicle's [[kinetic energy]] upon braking. These systems include

*[[Regenerative braking ]]systems and
*[[Kinetic energy recovery system]]s.

==Other useful pages==
*[[Octane rating]]
*[[Engine knocking]]
*[[Cetane number]]
*[[Improving fuel efficiency]]
