Embodiment Construction

[0022] According to Fig. 1, device 1 comprises a turbocharged piston type internal combustion engine 2, and it has six in-line cylinders 3, and their suction pipe 4 is connected on the manifold 5 that connecting flange 7 is arranged, and the fresh mixture pipe section module 8 connects its second end connection 9 for outflow to the connecting flange 7 . A first end connection 10 for inflow is coupled via a line 11 to an outflow 12 of an intercooler 13 , whose inflow 14 is coupled via a line 15 to an outflow 16 of a turbocompressor 17 . The air filter 19 is connected via a line 20 to the inlet 18 of the turbo compressor 17 . The turbocompressor 17 forms part of an exhaust gas turbocharger 22 , whose exhaust gas turbine 23 has its inlet 24 connected to an outlet 25 of an exhaust manifold 26 . The turbo compressor 17 and the exhaust gas turbine 23 are fixed on the shaft 21 . Cylinder 3 is connected with exhaust manifold 26 through exhaust pipe 27 . The outlet 28 of the exhaust...

Abstract

The present invention relates to a fresh mixing air feeding device which is used for the turbocharging piston type internal combustion with a fresh mixing air tube, the device includes a compressed air joint (42) which is sideways introduced to the tubular inner cavity (57) and is provided with a flow adjusting device (68), and an adjustable valve (60) arranged in the inner cavity (57) for flow regulating, wherein, the inner cavity (57) is limited with boundary by a first end joint (10) for inflow and a second end joint (9) for the outflow of the pressure charging air of the exhaust-driven turbocharger (22), wherein, the fresh mixing air tube is designed to be the form of the sole module (8), the two end joints (9 and 10) at the casing (89) is designed to be the form of the tube joint (86 and 87), and except for this they are suitable to be the supporting device of the module (8).

Description

technical field [0001] The invention relates to a fresh-mixture supply device for a turbocharged piston internal combustion engine with a fresh-mixture line arrangement, comprising a compressed air connection with a flow regulating device that opens laterally into a tubular interior, and a Adjustable flaps for flow regulation also provided in the inner chamber, wherein the inner chamber is connected by a first end connection for the inflow and a second end connection for the charge air outflow of the exhaust gas turbocharger Define boundaries. Background technique [0002] A fresh-air mixture supply device of the type according to the invention serves to support an exhaust gas turbocharger. Especially in the low speed range of a turbocharged reciprocating internal combustion engine, the connected exhaust gas turbocharger usually cannot provide the required boost pressure due to insufficient drive energy. The driver can perceive these occurrences during the air supply from ...
