Dual outlet turbocharger and twin aftercoolers for a diesel engine

Claim 2

An improvement for a sixteen cylinder diesel engine comprising: the adaptation of a turbocharger having twin discharge ducts to the engine by means of a hollow adapter member, and the adaptation of a pair of aftercoolers to the engine such that each aftercooler is in communication with one duct of said turbocharger, said turbocharger and said aftercoolers being mounted on said adapter member so that said turbocharger is centrally located at the front of said engine, said aftercoolers being mounted on said adapter member in symmetrical relationship on either side of said turbocharger.

Claim 3

The ALCO®engine of claim 1 wherein: said adapter member serves to provide support for said aftercoolers, as well as said turbocharger, said adapter member is essentially hollow, said hollow interior being in communication with the outlets of said aftercoolers, said adapter also being in communication with the air intake for said engine.

Claim 4

The engine as claimed in claim 1 wherein said adapter member is provided with suitable internal passages for coolant and lubrication conduits for the supply and return of said coolant and lubricant to and from said turbocharger.

Claim 5

A modified ALCO®251 16 cylinder diesel engine in which a prior art ALCO® 165 turbocharger and its single aftercooler are replaced with a GE 7S1716 twin discharge duct turbocharger and a pair of aftercoolers which are supportedly mounted on a hollow adapter member on said engine such that space requirements for said ALCO® engine in its modified and unmodified form occupy substantially the same space wherein said hollow adapter member is mounted on said engine so as to have the interior of said hollow adapter is in communication with the air intake of said engine, said turbocharger being mounted on said adapter member, said twin aftercoolers being supported on said adapter member, such that each aftercooler is metrically located with respect to a vertical plane passing through the axis of the crankshaft of said engine the longitudinal axis of each aftercooler being in parallel to said axis, such that the coolant tubes of each intercooler are parallel to said axis.

Claim 6

A modified ALCO®251 16 cylinder diesel engine in which a prior art ALCO® 165 turbocharger and its single aftercooler are replaced with a GE 7S1716 twin discharge duct turbocharger and a pair of aftercoolers which are supportedly mounted on a hollow adapter member on said engine such that space requirements for said ALCO® engine in its modified and unmodified form occupy substantially the same space wherein said hollow adapter member is mounted on said engine so as to have the interior of said hollow adapter is in communication with the air intake of said engine, said turbocharger being mounted on said adapter member, said twin aftercoolers being supported on said adapter member, such that each aftercooler is metrically located with respect to a vertical plane passing through the axis of the crankshaft of said engine the longitudinal axis of each aftercooler being in parallel to said axis, such that the coolant tubes of each intercooler are parallel to said axis.

Claim 7

An ALCO® engine as claimed in claim 4, wherein each aftercooler is in communication with the output of each discharge duct, and the outlet of each aftercooler is in communication with the interior of said hollow adapter member, and said adapter member serves also to supply and return lubrication and coolant to said turbocharger.
