    • An internal combustion engine has at least one cylinder and at least one gas exchange valve (1; 1a, 1b) controlled by a first cam (14) on a first camshaft (16) and by a second cam (15) on a second camshaft (17), at least one camshaft (16, 17) having an adjustable phase position in order to modify the control times of the gas exchange valve (1; 1a, 1b). The first cam (14) acts upon actuating means (6, 10) and the second cam (15) upon actuating means (6, 10) which actuate the gas exchange valve (6, 10). The actuating means (6, 10) are designed in such a way that the gas exchange valve (1) opens only when both the first cam (14) and the second cam (15) are acting upon the actuating means (6, 10). A simple structure with very high degrees of freedom for the control is achieved in that the actuating means (6, 10) comprise a lever which actuates the gas exchange valve (1; 1a, 1b) and is actuated by both cams (14, 15).
    • 本发明涉及具有与至少一个汽缸和至少一个气体交换阀内燃内燃机;经由第二经由第一凸轮(14)和一个第二凸轮轴(17)由第一凸轮轴(16)形成(1 1A,1B) 凸轮(15)被控制,至少一个凸轮轴(16,17),用于改变气体交换阀的控制时间(1; 1A,1B)被设计为在它们的相位位置,可调节的,其中,所述第一凸轮(14)上的致动装置(6,10 )作用和所述第二凸轮(15)的致动装置(6,10)作用,该致动装置(6,10)的气体交换阀(1; 1A,1B)被致动,其中,所述致动装置(6,10)被形成为使得 当且仅打开气体交换阀(1)是当第一凸轮(14)和在致动装置(6,10)的行为的第二凸轮(15)。 具有非常大的程度在控制自由的简单的结构实现,所述致动装置(6,10)包括一个气体交换阀的杠杆(1; 1A,1B)被操作和两个凸轮(14,15)被致动。
