Dispositivo para acondicionar la atmósfera en ensayos de motores de combustión interna alternativos, procedimiento y uso de dicho dispositivo

摘要

The invention relates to a device for conditioning the atmosphere in the testing of engines, comprising an entry duct connected to an engine inlet, an exit duct connected to the engine outlet, a communication duct that connects the entry duct to the exit duct, a bypass valve in the entry duct, a super-charging turbo assembly in the entry duct, a heat exchanger in the exit duct, and a turbocharger after the heat exchanger. In addition, the device comprises a first three-way valve that connects the entry duct to the exit duct, a valve that is entirely or not at all in the exit duct, a second three-way valve in the exit duct, a regulation valve in a duct that connects the exit duct to the atmosphere, and a section of the exit duct that connects the exchanger to the communication duct.
