This abstract first appeared for US patent application 20250137413 titled 'APPARATUS AND METHOD FOR CONTROLLING INTAKE AIR TEMPERATURE
Original Abstract Submitted
methods for operating internal combustion engines and methods for controlling intake air temperature in engines of vehicles are provided. an engine includes an intake system configured to deliver intake air to the internal combustion engine; an exhaust system configured to discharge exhaust gas from the internal combustion engine; and an exhaust gas recirculation (“egr”) system configured to selectively deliver a portion of the exhaust gas to the intake system. the internal combustion engine is located in an underhood zone; the intake system includes a first intake pipe having an outlet in communication with the intake system and having an inlet located outside of the underhood zone to receive ambient air; and the intake system includes a second intake pipe having an outlet in communication with the intake system and having an inlet located within the underhood zone to receive air warmed by the internal combustion engine.
