Abstract (en)
The present disclosure relates to a cooling assembly (100) for a cylinder of an internal combustion engine comprising a cylinder liner (40) and a cooling jacket (42). The cylinder liner (40) comprises a circumferential groove (50) formed in an upper part of an outer surface (41) of the cylinder liner (40). A circumferentially extending guiding surface (46) is formed in the outer surface (41) of the cylinder liner (40) and merges with a lower end (51) or an upper end (55) of the groove (50). The cooling jacket (42) is disposed around the cylinder liner (40) and includes a guiding portion (62) facing the guiding surface (46). A tear-off edge (54) is formed in cooling jacket (42) adjacent to the lower end (51) or the upper end (55) of the groove (50). In this manner, a ring-shaped nozzle (53) for the coolant entering the groove (50) is formed, and a turbulent flow of coolant is produced that enters the groove (50) to efficiently cool the cylinder liner (40).
