Abstract
Abstract Described is a device for moistening the inlet air of internal combustion engines having a turbo-supercharger. The device comprises moistening means through which the inlet air and the moistening liquid flow and contact with one another. The moistening means is disposed upstream or the compressor of the turbo-supercharger in flow direction of the inlet air. In the flow path of the inlet air upstream of the moistening means an air/air heat exchanger is disposed which serves for preheating the inlet air and which is flown through by the atmospheric inlet air and the moistened and compressed inlet air from the compressor.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
180 words
An internal combustion engine comprising: a plurality of cylinders generating an exhaust gas; a turbo-supercharger connected to said cylinders and having a turbine receiving said exhaust gas and driven thereby, and a compressor for compressing air to be fed to said cylinders and driven by said turbine; an air/air heat exchanger; a first conduit connected to said air/air heat exchanger for supplying atmospheric air thereto for heating in said air/air heat exchanger, a second conduit connecting said compressor to said air/air heat exchanger for supplying compressed air heated by said compressor to said air/air heat exchanger whereby said compressed air is cooled, a third conduit connected to said air/air heat exchanger for delivering compressed air to said cylinders, and a fourth conduit for delivering heated atmospheric air; and a moistener upstream of said compressor and downstream of said air/air heat exchanger, said moistener being connected to a source of water, to said fourth conduit and to said compressor for moistening heated atmospheric air delivered by said fourth conduit and supplying moistened heated atmospheric air to said compressor for compression therein.
Claim 2
Dependent Claim
180 words
An internal combustion engine comprising: a plurality of cylinders generating an exhaust gas; a turbo-supercharger connected to said cylinders and having a turbine receiving said exhaust gas and driven thereby, and a compressor for compressing air to be fed to said cylinders and driven by said turbine; an air/air heat exchanger; a first conduit connected to said air/air heat exchanger for supplying atmospheric air thereto for heating in said air/air heat exchanger, a second conduit connecting said compressor to said air/air heat exchanger for supplying compressed air heated by said compressor to said air/air heat exchanger whereby said compressed air is cooled, a third conduit connected to said air/air heat exchanger for delivering compressed air to said cylinders, and a fourth conduit for delivering heated atmospheric air; and a moistener upstream of said compressor and downstream of said air/air heat exchanger, said moistener being connected to a source of water, to said fourth conduit and to said compressor for moistening heated atmospheric air delivered by said fourth conduit and supplying moistened heated atmospheric air to said compressor for compression therein.
Claim 3
Dependent Claim
47 words
The internal combustion engine defined in claim 1 , further comprising another moistener disposed upstream of said air/air heat exchanger and connected thereto by said first conduit and heating means for inlet air supplied to said another moistener disposed upstream thereof and supplying the atmosphering air thereto.
Claim 4
Dependent Claim
42 words
The internal combustion engine defined in claim 1 , further comprising another moistener disposed between said compressor and the moistener upstream thereof and a heater upstream of said another moistener and traversed by the heated atmospheric air delivered by said fourth conduit.
Claim 5
Dependent Claim
46 words
The internal combustion engine defined in claim 1 , wherein an air/water heat exchanger is provided along a path of air supplied to said compressor and receives cooling water of the engine for transferring heat energy of the cooling water to air supplied to said compressor.
Claim 6
Dependent Claim
22 words
The internal combustion engine defined in claim 1 , further comprising a flow device connected between said third conduit and said cylinders.
Claim 7
Dependent Claim
28 words
The internal combustion engine defined in claim 5 , further comprising a bypass line with a valve connected across an inlet and an outlet of said cooling device.
Claim 8
Dependent Claim
21 words
The internal combustion engine defined in claim 1 , further comprising another moistener connected between said third conduit and said cylinders.
Claim 9
Dependent Claim
29 words
The internal combustion engine defined in claim 7 , wherein said another moistener is provided with a heat exchanger for heating a moistening medium supplied to said another moistener.
Claim 10
Dependent Claim
24 words
The internal combustion engine defined in claim 1 , further comprising an air filter connected to said first conduit of said air/air heat exchanger.
Claim 11
Dependent Claim
35 words
The internal combustion engine defined in claim 1 , further comprising a cooling circulation connected to said cylinders and supplied with cooling water, said cooling circulation including a heat exchanger for cooling the cooling water.
Claim 12
Dependent Claim
25 words
The internal combustion engine defined in claim 10 , wherein said heat exchanger is supplied for cooling said cooling water is supplied with sea water.
