Claim 0:
1. A split cycle type 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 to a relating piston and a relating head and arranged to feed the combustion cylinder with compressed air through said admission valve,
first control means of said at least one admission valve and
second control means of said at least one exhaust valve,
wherein the piston of the combustion cylinder is associated with a crankshaft by means of a crank mechanism so that the combustion cylinder performs a two-strokes cycle and wherein
when the engine is in a firing condition, said second control means are arranged to cause a first opening event of the at least one exhaust valve in a first predetermined angular position of the crankshaft and wherein
when the engine is in engine braking condition, said second control means are arranged to move said first event into a second predetermined angular position (EXB, EXB_1) out of phase by about 180 degrees with respect to said first angular position and said first control means are arranged to generate a first opening event of the admission valve approximately at a crankshaft angular reference position (0.0) in which the piston of the combustion cylinder is at a relating top dead center.
