Engineering and production services of PJSC TMZ continue to work on the comprehensive modernization of the engine for Kirovets K-7 tractor, manufactured for the main consumer – Peterburgsky Traktorny Zavod JSC.

The upgraded engines use an air-to-air charge air cooler (CAC). The advantages of the upgraded air-to-air CAC engine are as follows: cooling is carried out with atmospheric air, the design and production technology are simpler, the cost is lower, and fuel consumption is lower.

Since 2023, a coolant pump with a reinforced bearing assembly has been used in tractor engine modifications. This spring, engines with cast-iron cylinder heads are going into serial production. And beginning July, a new cylinder block casting technology will be used.

In the near future, work on the modernization of tractor engines will continue: it is planned to increase the engine capacity in the range of 460-600 HP, use a new piston group, and Common Rail type fuel equipment.
