The first German jet engines built during the Second World War used a mechanical APU starting system designed by the German engineer Norbert Riedel.It consisted of a 10 horsepower (7.5 kW) two-stroke flat engine, which for the Junkers Jumo 004 design was hidden in the engine nose cone, essentially functioning as a pioneering example of an auxiliary power unit for starting a jet engine.
Around 300,000 refrigerator trucks with auxiliary power units are on the road in the United States, according to a 2013 estimate. [3] In recent years, truck and fuel cell manufacturers have teamed up to create, test and demonstrate a fuel cell APU that eliminates nearly all emissions [4] and uses diesel fuel more efficiently.
The range-extender option costs an additional US$3,850 in the United States, [27] an additional €4,710 (~ US$6,300) in France, [28] and €4,490 (~ US$6,000) in the Netherlands. [29] The range-extender option of the BMW i3 was designed to meet the CARB regulation for an auxiliary power unit (APU) called REx.

An electric starter with sufficient power to turn a large diesel engine would itself be so large as to be impractical so there is a need for an alternative system. An air start system has three main components along with various safety components, namely the air start injector, the distributor and the air receivers.
Maximum power output: 75 kW (100 shp) at 37,000 rpm or 60 kW DC from TCP-24 electric generator at 9,250 rpm gearbox output Overall pressure ratio : 3.15:1 Air mass flow: 1.75 kg/s (231 lb/min) at 37,000 rpm
A Honeywell GTCP36-150(CX) auxiliary power unit mounted in the tail of a Cessna Model 750 Citation X. Honeywell auxiliary power units are a series of gas turbine auxiliary power units (APU) made by Honeywell Aerospace. Honeywell started manufacturing APUs in the early 1950s and since then they can be found on many aircraft. [1]
