摘要:
A propulsion assembly for a motor vehicle includes an internal combustion engine (6) comprising at least one movable member (21) as a function of an operating speed of said engine (6), a turbocharger (10) comprising a turbine (11) adapted to expand exhaust gases of said engine (6) to generate work and a first compressor (12) adapted to compress air by means of the work generated by the turbine (11), an intake line (19) connecting an outlet of the first compressor (12) to an intake manifold (15) of said engine (6) to supply compressed air from the first compressor (12) to said engine (6), characterized in that the intake line (19) comprises a second compressor (22), which in turn comprises a compressor shaft (23) rotatable about a first axis (Y) and is configured to further compress the compressed air from the first compressor (12) via a rotation of the compressor shaft (23). The propulsion assembly further comprises mechanical transmission means (25) configured to couple the movable member (21) to the compressor shaft (23), thereby determining a transmission of motion from the movable member (21) to the compressor shaft (23).
摘要:
An engine device 1 includes an exhaust manifold 4 provided on an exhaust side surface which is a first side surface of a cylinder head 2 and a two-stage turbocharger 30 that is driven by exhaust gas discharged from the exhaust manifold 4. The two-stage turbocharger 30 includes a high-pressure turbocharger 51 coupled to the exhaust manifold 4, and a low-pressure turbocharger 52 coupled to the high-pressure turbocharger 51. The high-pressure turbocharger 51 is arranged on a side of the exhaust manifold 4. The low-pressure turbocharger 52 is arranged above the exhaust manifold 4. An exhaust gas outlet 58 of the high-pressure turbocharger 51 and an exhaust gas inlet 60 of the low-pressure turbocharger 52 are coupled with each other through a flexible high-pressure exhaust gas pipe 59.
