Claim 15:
16. A method for operating an engine brake by means of a split cycle internal combustion engine comprising at least one combustion cylinder associated with a relating piston and a relating head, equipped with at least one admission valve and an exhaust valve, at least one compressor cylinder associated with a relating piston and a relating head and arranged to supply the combustion cylinder with compressed air through the at least one admission valve, first control means for said at least one admission valve and second control means for said at least one exhaust valve, wherein the piston of the combustion cylinder is associated with a crankshaft by means of a crank mechanism and wherein the second control means, when the engine is in firing condition, are arranged to cause a first opening event of the at least one exhaust valve in a first predetermined angular position of the crankshaft, the method including the following steps to operate the engine brake:
inhibition of fuel injection in said at least one combustion cylinder,
repositioning of said first event in a second predetermined angular position (EXB, EXB_1) out of phase by about 180 degrees with respect to said first angular position.
