Reciprocating internal combustion engine and method for valve control in a reciprocating internal combustion engine

摘要

The invention relates to a reciprocating internal combustion engine having a crankshaft and a plurality of pistons (14) connected to the crankshaft, with a plurality of cylinders (12) in which each one of the pistons (14) moves, with at least one camshaft (22) and per cylinder (12 ) with at least one exhaust valve (20), at least one exhaust cam follower (32) actuating the exhaust valve (20), and during a braking operation with a brake cam (28) held on the or one of the camshafts (22) In order to extend the life of the reciprocating internal combustion engine, it is proposed that at least two of the brake cams (28) have different cam profiles from each other and / or that at least two of the brake cams (28) have a different phase position to a movement of the respective piston (14) in the associated cylinder (12).
