Abstract (en)
The present disclosure refers to a piston (5) for an internal combustion engine. The piston (5) comprises at least one cooling chamber (30) preferably configured to generate a shaker cooling effect by partially filling of the cooling chamber (30) with a fluid, e.g., a coolant such oil, during use of the piston (5). The cooling chamber (30) has an inner surface (35) that is at least partly provided with a non-stick coating (50), preferably selected to inhibit or at least reduce contaminate accumulation or deposit during engine operation. The disclosure also refers to a method for manufacturing a piston (5) configured to be used in an internal combustion engine.
