Diesel engine with high-pressure injection and charging function, and piston or a diesel engine

Abstract

The invention relates to a diesel engine with high-pressure injection and supercharging (Question to inventor: which components define a “diesel engine” with the corresponding properties and/or a compression temperature of more than 700° C. and/or a combustion temperature of more than 1200° C., a cylinder or several cylinders with a respective cylinder bore, a connecting rod associated with a respective cylinder and a piston arranged in the respective cylinder bore with a top side, an under side and a circumferential surface with a temperature of more than 700° C. and/or a combustion temperature of more than 1200° C., an under side and a circumferential surface with a nominal diameter, the upper side being designed to absorb pressure forces of a gas inside the respective cylinder, the underside having a connecting rod holder with an undercut acting in a tensile and a pressure direction, so that the connecting rod holder is designed to positively receive a head region of the respective connecting rod which corresponds to the receptacle and is pivotable about a pivot axis, and the circumferential surface is designed to guide the piston in the respective cylinder bore along an axis of movement and with a ring groove for a piston ring for sealing the piston with respect to the respective cylinder bore and has a circumferential collar extending from the upper side with a height arranged between the upper side and the ring groove for the piston ring. Furthermore, the invention relates to a corresponding piston of a diesel engine.
