A compound turbocharger system (2, 2', 112) for an engine/compressor unit (4, 4') is disclosed including a pair of conventional turbochargers (14, 16, 111, 113) including turbine components (18, 22, 114, 116) connected in series to convert exhaust gas energy from the engine cylinders (6, 104, 106, 108, and 110) into mechanical energy for driving a pair of impeller-type compressor components (26, 28, 118 and 120) arranged to supply sufficient quantities of air to the intake manifold (42, 122) of the engine cylinders (6, 104, 106, 108, 110) and to the intake manifold (40, 124) of the compressor cylinders (8, 100, 102). In one embodiment, the impeller-type compressor components (26, 28) are arranged in parallel. In a second embodiment, the impeller-type compressor components (118, 120) are arranged in series with the air supplied to the intake manifold (122) of the engine cylinders (104, 106, 108, 110) being provided by the first compressor component (118). Smooth operation of the engine/compressor unit (4, 4' ) including substantial self-proportioning of the air boost to both the engine cylinders (6, 104, 106, 108, 110) and compressor cylinders (8, 100, 102) is assured by means of a compressor cylinder control means (50) and engine throttle means (51) for adjusting total compressed air output and engine rpm to the compressed air being utilized by enabling or disabling compressor cylinders (8, 100, 102) one at a time in succession and by correspondingly adjusting the fuel flow to the engine cylinders (6, 104, 106, 108, 110). A compound turbocharger system (2') is also disclosed for supplying compressed air to an air pressure operated conveyor (150).
