=== Supercharging & turbocharging ===
{{see also|Turbo-diesel}}
[[Forced induction]], especially turbocharging is commonly used on diesel engines because it greatly increases efficiency and torque output.<ref name="Reif_2014_41" /> Diesel engines are well suited for forced induction setups due to their operating principle which is characterised by wide ignition limits<ref name="Pischinger_2016_348" /> and the absence of fuel during the compression stroke. Therefore, knocking, pre-ignition or detonation cannot occur, and a lean mixture caused by excess supercharging air inside the combustion chamber does not negatively affect combustion.<ref name="Reif_2017_16" />
