Embodiment Construction

[0104] The following description relates to systems and methods for cooling devices.

[0105] now go to figure 1 , which schematically shows a first embodiment of a supercharged internal combustion engine 1 together with an exhaust gas recirculation device 4 .

[0106] The internal combustion engine 1 has an intake system 3 for supplying charge air to the cylinders, and has an exhaust gas discharge system 2 for discharging exhaust gas from the cylinders.

[0107] For supercharging purposes, the internal combustion engine 1 is equipped with an exhaust-gas turbocharger 6 comprising a turbine 6b arranged in the exhaust gas discharge system 2 and a compressor arranged in the intake system 3 6a.

[0108] Furthermore, an exhaust gas recirculation (EGR) device 4 is provided with two recirculation lines 4 a , 4 b , wherein a cooler 5 a , 5 b is arranged in each recirculation line 4 a , 4 b respectively. In each case, the coolers 5a, 5b have a coolant jacket for conducting the coola...

Abstract

The present application relates to a supercharged internal combustion engine with cooled exhaust gas recirculation. Methods and systems for cooling devices are provided. In one example, a method for cooling a plant includes adjusting exhaust gas recirculation to a first cooler and a second cooler of the cooling plant in response to one or more of an exhaust gas recirculation demand and an energy recovery demand and / or or exhaust flow.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102016218990.5 filed on September 30, 2016. The entire contents of the applications cited above are hereby incorporated by reference in their entirety for all purposes. technical field [0003] The present specification generally relates to methods and systems for controlling a combined low-pressure exhaust gas recirculation (LP-EGR) and heat recovery system with combined exhaust gas recirculation (EGR) cooling and heat recovery functions. Background technique [0004] An internal combustion engine of the described type is used as a motor vehicle drive unit. Within the context of the present disclosure, the expression "internal combustion engine" includes diesel engines and Otto cycle engines and also hybrid internal combustion engines utilizing a hybrid combustion process, as well as hybrid drives, which include not only internal combustion engines b...
