6M43C

Описание двигателя:

6M43C представляет собой шестицилиндровый, рядный, четырехтактный, дизельный двигатель, нереверсивный, с турбонаддувом, промежуточным охлаждением и с прямым впрыском топлива.

Буква "С" в названии модели означает возможность работы двигателя на тяжелом топливе (до 700 сСт при 50 °С).
