Abstract: A turbocharged automotive system includes an internal combustion engine and a Long Route Exhaust Gas Recirculation system connected to an exhaust line of the engine. The LR-EGR system is equipped with a LR-EGR cooler, which is cooled by a LR-EGR coolant circuit receiving coolant from an engine coolant circuit. The turbocharged automotive system further includes a low temperature coolant circuit and a connecting element for connecting the LR-EGR coolant circuit with the low temperature coolant circuit bypassing the engine coolant circuit.

Abstract: A method is disclosed for operating an internal combustion engine having a turbocharger and an exhaust gas recirculation pipe fluidly connecting an exhaust system to an air intake system upstream of a compressor of the turbocharger. A first value of a parameter indicative of the density of a mixture of fresh air and exhaust gas in the air intake system is determined. A flowing of exhaust gas through the exhaust gas recirculation pipe is interrupted if the first value is lower than a first reference value thereof.

Abstract: An EGR valve assembly includes an intake gas passage, an exhaust gas passage, an outlet passage, a movable intake gas flap for changing an effective cross section of the intake gas passage and a movable exhaust gas flap for changing an effective cross section of the exhaust gas passage. The intake gas flap includes at least one channel connecting an inlet port on a upstream-side surface of the flap with an outlet port on a downstream-side surface of the flap.

Abstract: A method is disclosed for operating an internal combustion engine equipped with an aftertreatment device. The internal combustion engine is equipped with a cylinder having an exhaust gas port intercepted by an exhaust valve, the exhaust valve being actuated by means of a Variable Valve Actuation (VVA) system, An aftertreatment device regeneration is detected, and the exhaust valve closure is anticipated using the Variable Valve Actuation (VVA) system during the aftertreatment device regeneration to provide an exhaust valve actuation profile having an anticipated exhaust valve closure with respect to a baseline exhaust valve actuation profile.

Abstract: A cooling system for an internal combustion engine is disclosed which includes a coolant pump for circulating a coolant in a coolant circuit and a radiator disposed in the coolant circuit. A charged-air cooler is disposed in the coolant circuit downstream of the radiator, and a long-route exhaust-gas-recirculation cooler disposed in the coolant circuit downstream of the charged-air cooler and upstream of the radiator.
