Single-circuit cooling system for increasing the performance of supercharged internal combustion engines and method

摘要

The invention relates to an internal combustion engine (1) with an exhaust gas turbocharger (2) for charging and with a single-circuit cooling system (3) for cooling the internal combustion engine by means of a liquid coolant (4), wherein the single-circuit cooling system in the cooling circuit (5) at least one recooler (6), a charge air cooler (7), optionally an oil cooler (8) has a coolant pump (9) and the internal combustion engine to be cooled (1). In order to increase the performance of the internal combustion engine, it is provided that a first bypass (10) bridging the at least one charge air cooler (7) and optionally one or more oil coolers (8) and / or a second one the at least one recooler ( 6) bridging bypass (11) is provided, wherein at least one of the two bypasses (10, 11) has a throttle body (12), preferably a diaphragm (13). Moreover, the invention relates to a method for increasing the performance of an internal combustion engine with charging. According to the invention, it is proposed that a coolant flow coming from the internal combustion engine is divided into a first and second partial flow and the first partial flow is supplied to the recooler, while the second partial flow is conducted past the at least one recooler and the at least one charge air cooler via a first bypass and preferably by means of a throttling member is throttled and these partial streams are reunited before the coolant pump and / or throttled past the recooler bypass flow of the first partial flow of the coolant is throttled.
