Peculiarities of balancing in-line two and four-cylinder piston engines

Abstract

The balancing of the kick reactive torque (KRM) in in-line two- and four-cylinder internal combustion engines is considered. It is shown that these internal combustion engines can be balanced by a special arrangement of the axes of the balancing shafts, which ensure the balance of the inertia forces of reciprocating moving masses. With the help of the developed programs, a comparative analysis of the possibilities of balancing the kick reactive torque with different layouts of the balancer shafts for the considered internal combustion engines was carried out. It is established that this balancing method is the most effective for two-cylinder internal combustion engines. The expediency of developing devices for regulating the position of the balance shafts axes is shown. Keywords: in-line two-cylinder and four-cylinder internal combustion engines, balance, balance shaft, kick moment. gusarov39@yandex.ru, apelinskiy_mami@mail.ru, prvm@rambler.ru
