| 发明名称 | Valve train of a reciprocating piston combustion engine | ||
| 摘要 | In a valve train of a reciprocating piston combustion engine, comprising cylinders controlled by at least three valves (1, 2) actuated by lobes (5, 6) of a camshaft (3; 4), wherein at least two valves (1; 2) operate equally in terms of function as intake or outlet valves (1; 2), the engine driving and/or braking operation are to be improved. For this purpose, such a valve train is characterized in that the lobes (3, 4) of the camshafts (3, 4) actuating the at least two equally operating valves in terms of function, which are primary and secondary valves (1p, 1s; 2p, 2s), are configured so that they are phase-adjustable in relation to each other. | ||

| 主权项 | 1. A valve train of a reciprocating piston combustion engine, comprising: at least three valves actuated by lobes of a camshaft, wherein the at least three valves are associated with a respective engine cylinder, and at least two of the at least three valves operate as a primary and a secondary valves, and wherein the lobes of the camshaft associated with the at least two of the at least three valves are phase adjustable with respect to one another, wherein the at least two of the at least three valves are outlet valves that are associated with the respective engine cylinder, and wherein an adjustable setting of the lobes is configured to open one of the outlet valves during an operation stroke of the engine to selectively perform an engine braking operation. | ||
