TWO-STROKE PISTON DIESEL ENGINE Russian patent published in 2013 - IPC F02B23/00 F02F1/24 

FIELD: power engineering.

SUBSTANCE: two-stroke piston diesel engine comprises a cylinder with blowdown windows, a piston installed in it with a steam, a cylinder lid with one outlet valve and one or two nozzles installed in it. A steel insert is installed (pressed) in the cylinder lid with end ledges in the form of a ring with tangential slots, forming channels that connect the zone of displacement of air volume limited between the outer diameter of the insert ring and the cylinder diameter and flat sections of the insert and the bottom of the piston with the combustion chamber, and the vector of speeds has identical direction, the insert ring enters the cylindrical part of the groove in the piston bottom with the piston position in the upper dead point. The rounded edge is made from heat-resistant steel pressed in the bottom of the piston in the form of a ring or is coated with fire-resistant steel, for instance, by the method of plasma sputtering.

EFFECT: increased capacity, improved environmental parameters.
