Abstract (en)
[origin: WO2011069836A1] The invention relates to an internal combustion engine (4) having an electrohydraulic valve control (1) for the variable lift drive of a gas exchange valve (3) wherein the hydraulic valve (15) is actuated by an electronic actuating means (16) such that a gas exchange valve stroke (19) required for a load change is adjusted during the cold start phase of the internal combustion engine (4) within a minimum stroke height (h-min) and a maximum closing time (a-max). The invention further relates to a method for operating the internal combustion engine (4).
