The "inter" prefix in the device name originates from its use as a cooler in between compression cycles. Typically in automobiles the intercooler is placed between the turbocharger (or supercharger) and the engine (the piston compression produces the next compression cycle). A more descriptive or informative term would be aftercooler/chargecooler, thereby removing any ambiguity that the vehicles have sequential two-stage turbocharging. Aircraft engines are sometimes built with charge air coolers that were installed between multiple stages of forced induction, thus the designation of "inter". In a vehicle fitted with twin stage turbocharging, it is possible to have both an intercooler (between the two turbocharger units) and an aftercooler (between the second-stage turbo and the engine). The JCB Dieselmax diesel land speed record-holding car is an example of such a system. In general, an intercooler or aftercooler is said to be a charge-air cooler.
