ABSTRACT:
This invention relates to a method and an arrangement for controlling the working cycle of an internal combustion engine (1) which is supercharged by at least one exhaust-driven turbo-compressor (4,5). Each cylinder of the engine has an inlet valve (2) to which air is supplied from the turbo-compressors (4,5) through an induction or inlet line (12), and an outlet valve (3) from which the exhaust gases are passed through an outlet line (13) to the turbo-compressors (4,5). Each cylinder is also provided with a separate pressure control valve (19) which is connected to the induction system by a pressure control line (20) and which is intended to open when the piston, during the compression stroke, is located in a distance from the bottom-dead-center position (C) of the piston, and is intended to close when the piston, during the compression stroke, is located at a second predetermined position (D) in the cylinder at a greater distance from the bottom-dead-center position (C) of the piston.
