Structural arrangement in a low-temperature turbocompressor for an internal combustion engine

Abstract

A low-temperature turbocompressor structural arrangement for an internal combustion engine for using energy that is available but unused during operation to cool the air supplied to the engine by supercharging. The temperature of the air compressed by the compressor is reduced by a cooling system and the air is then conveyed to a further turbine actuated by the intake air flow of the engine. The structural arrangement may be mounted in full or in part, and also each component may be fitted into existing systems.

1 . “The low-temperature turbocompressor structural arrangement for an internal combustion engine” relates to a system for using the energy that is available but unused during operation of an internal combustion engine to cool the air supplied to said engine by supercharging, applicable to internal combustion engines of any type, characterized in that it supplies the engine with air that is colder and therefore denser than a common turbocompressor, and does so using the same amount of energy as consumed by this latter. 
     
     
         2 . “The low-temperature turbocompressor structural arrangement for an internal combustion engine” relates to a system for using the energy that is available but unused during operation of an internal combustion engine to cool the air supplied to said engine by supercharging, applicable to internal combustion engines of any type, as described in  001 , formed by a system comprising a turbocompressor and turbines and characterized in that the turbocompression system is formed by the exhaust gas turbine (T 1 ) rigidly connected to the compressor (C), in which said compressor conveys the fluid to a fluid cooler that can be an intercooler (IC), but that is not limited to this or other types of heat exchanger, nor to a specific coolant fluid, since any type can be used, and sequentially, the flow of cooled compressed air is conveyed to an intake gas turbine (T 3 ) with pressure regulated by a return valve (V) that prevents the overloading of the engine (M) and directs the excess flow to a return gas turbine (T 2 ) that returns the air to the inlet of the compressor (C), in which the turbines T 2  and T 3  are rigidly connected to the compressor (C) and to the exhaust gas turbine (T 1 ). 
     
     
         3 . “The low-temperature turbocompressor structural arrangement for an internal combustion engine” relates to a system for using the energy that is available but unused during operation of an internal combustion engine to cool the air supplied to said engine by supercharging, applicable to internal combustion engines of any type, as described in 1 and 2, with alternative structures characterized in that the system can use compressors and turbines of variable geometry or any other compressors or turbines that can be installed on the same shaft, with any type of assembly constraining the movement thereof, include multiple stages with turbocompressors on separate shafts or on the same shaft as the first, be used in conjunction with other air compressors, mechanical ( FIG. 6 ) or otherwise, or even with additional turbocompressors, all in series ( FIG. 5 ) or in parallel ( FIGS. 2, 3 and 4 ) with the former, use compressors and turbines of variable geometry, with multiple stage expansion and/or compression, in two- or four-stroke Otto-cycle or diesel engines, using additional heat exchangers and any coolant fluid, with the option of assembling fully or partially as required, in which each component part can be adapted to pre-existing systems.
