TWO-STROKE INTERNAL COMBUSTION ENGINE Russian patent published in 2021 - IPC F02B19/16 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in internal combustion engines. The internal combustion engine contains a cylinder (1) with a piston (2), a combustion chamber (3) and a pre-chamber (4). The pre-chamber (4) contains an ignition cavity (5) installed in the combustion chamber (3) and made in the form of a hemisphere. The longitudinal axis of the ignition cavity (5) coincides with the longitudinal axis of the cylinder (1). The ignition cavity (5) faces the outlet towards the piston (2). The approximate value of the distance from the side walls of the cavity (5) of the ignition of the pre-chamber (4) to the piston (2) at its upper dead center at the end of the compression stroke is determined from the ratio h=R/2π mm. Where h is the distance from the side walls of the ignition cavity of the pre-chamber to the piston at its upper dead center at the end of the compression stroke, R is the radius of the inner spherical surface of the ignition cavity, π =3.14…

EFFECT: improved eco-friendly characteristics.
