Editing Naturally aspirated engine (section)

== Applications ==
Most [[automobile]] petrol engines, as well as many small engines used for non-automotive purposes, are naturally aspirated.<ref>{{cite web |url=http://www.privatefleet.com.au/glossary/what-is-a-naturally-aspirated-engine/ |title=What is a Naturally Aspirated Engine ? |website=Private Fleet |access-date=2017-02-17 |quote=Most motor vehicle engines are naturally-aspirated engines; however, turbocharging and supercharging are currently a very popular way of boosting power output for a number car marques.}}</ref> Most modern diesel engines powering highway vehicles are [[Turbocharger|turbocharged]] to produce a more favourable [[power-to-weight ratio]], a higher [[torque curve]], as well as better [[fuel efficiency]] and lower [[Vehicle emissions control|exhaust emissions]]. Turbocharging is nearly universal on diesel engines that are used in [[Rail transport|railroad]], [[Marine propulsion|marine engine]]s, and commercial [[:wikt:stationary|stationary]] applications ([[Electricity generation|electrical power generation]], for example). Forced induction is also used with reciprocating [[aircraft engine]]s to negate some of the power loss that occurs as the [[aircraft]] climbs to higher altitudes.
