  • Controlling a pump conveying a coolant in a charging gas cooling circuit
    Patent number: 10533488
    Abstract: The invention describes is a method (27) for controlling a coolant-conveying pump (7) in a charge gas cooling circuit (3) in order to cool a charge gas (9) for an internal combustion engine, whereby the method involves: maintaining (29) an inlet temperature (51) of the charge gas (9) in a heat exchanger (13) that is configured to exchange heat between the charge gas (9) and the coolant; ascertaining (31) a target cooling output (21) on the basis of the inlet temperature (51, T21) of the charge gas (9) and on the basis of a target outlet temperature (T22target) of the charge gas (15) coming from the heat exchanger (13); determining (33) a change (23) of the target cooling output (21) over time, and providing (35) an actuation signal (25) for the pump (7) based on the target cooling output (21) and on the change (23) of the target cooling output over time.

  • Internal combustion engine with an exhaust-gas recirculation and method for operating an internal combustion engine
    Patent number: 8555864
    Abstract: An internal combustion engine has a high-pressure exhaust-gas recirculation line and a low-pressure exhaust-gas recirculation line with a low-pressure exhaust-gas recirculation valve. The low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system downstream of a turbine of an exhaust-gas turbocharger and opens into a fresh-air system upstream of a compressor of the exhaust-gas turbocharger. An exhaust-gas flap is disposed in the exhaust-gas system downstream from where the low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system. At least one pressure sensor is disposed in the low-pressure exhaust-gas recirculation line and configured such that the at least one pressure sensor determines a pressure difference in the low-pressure exhaust-gas recirculation line between a point upstream of the low-pressure exhaust-gas recirculation valve and a point downstream of the low-pressure exhaust-gas recirculation valve.
