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

A turbo compressor for an internal combustion engine having an air intake pipe and an exhaust pipe comprising:

• a first exhaust gas turbine having a first intake in fluid communication with the exhaust pipe and a first discharge in fluid communication with an ambient environment, the first exhaust gas turbine is fixedly attached to a first axle and rotates the first axle in response to a supply of pressurized exhaust gas from the engine;
• an intake gas turbine having a second intake in fluid communication with the air intake pipe and having a second discharge in fluid communication with the internal combustion engine, the intake gas turbine is fixedly attached to the first axle and rotates the first axle in response to a supply of air under pressure from an ambient environment;
• a return gas turbine having a third intake in fluid communication with the air intake pipe and a third discharge in fluid communication with a first compressor, the return gas turbine is fixedly attached to the first axle and rotates the first axle in response to a supply of air under pressure from a return pipe;
• the return pipe connecting the third intake to the air intake pipe;
• a valve installed in the return pipe for means of regulation of the returning mass flow;
• the first compressor having a fourth intake in fluid communication with the air intake pipe and a fifth intake in fluid communication with the third discharge, the fourth and fifth intakes being united or separated, the first compressor is fixedly attached to the first axle and rotates in response to the rotation of the first axle in order to supply pressurized air from the air intake pipe and the return gas turbine to the system, the first compressor having a fourth discharge in fluid communication with an intercooler, the fourth discharge combines the air from the intake pipe and the air from the return gas turbine;
• and,
• the intercooler having a sixth intake in fluid communication with the fourth discharge and a fifth discharge, the intercooler having a heat exchange surface between the sixth intake and the fifth discharge, a temperature of air in the sixth intake is higher than a temperature of air at the fifth discharge, the fifth discharge is in fluid communication with the second intake.
