9M32E
Описание двигателя:
9M32E представляет собой девятицилиндровый четырехтактный дизельный двигатель, нереверсивный, с турбонаддувом, промежуточным охлаждением и с прямым впрыском топлива.
Это новый двигатель, специально разработанный для обеспечения снижения стоимости эксплуатации при сохранении высокой безотказности работы. М32Е основан на проверенной версии М32С, но был оптимизирован для снижения расхода топлива и улучшения принятия нагрузки.
