Internal combustion engine, as well as a method for operating an internal combustion engine

摘要

The present invention relates to an internal combustion engine (1), having at least one cylinder (2), with a in the cylinder (2) arranged to be longitudinally movable piston (5) as well as with a piston cooling jet (10) for the introduction of cooling agent in the direction of the piston (5) and / or with at least one in the piston (5) constructed piston cooling channel (11). In this case, it is provided that the piston cooling jet (10) and / or the piston cooling channel (11) of a control device (16) which is associated with a control shaft (17) as well as a the control shaft (17) surrounding at least in some regions of the control element (18), wherein in the control shaft (17) a first coolant duct (21, 22) is present, the a lateral surface (23) of the control shaft (17) with the formation of at least a first cooling means switching opening (24, 25) engages, and the control element (18) for each cylinder (2) in each case at least a second coolant channel (27, 28, 29, 30) is formed, the one of the control shaft (17) which faces the inner peripheral surface (31) of the control element (18) with the formation of at least a second cooling means switching opening (32, 33, 34, 35) engages, so that a flow connection between a coolant source and the piston cooling jet (10) and / or the piston cooling channel (11) only in the case of at least partial overlap of the first cooling means switching opening (24, 25) and the second cooling means switching opening (32, 33, 34, 35) is present. The present invention also relates to a method for operating an internal combustion engine (1).
