Поршень - одна из важнейших деталей двигателя внутреннего сгорания. Он передает энергию сгорания топлива через палец и шатун коленчатому валу. Он вместе с кольцами уплотняет цилиндр от попадания продуктов сгорания в картер.

Pistons for diesel engines are thick-walled, high, with heavy bottom and bosses. They must retain functionality under high pressures in a cylinder and moderate rotational velocity of an engine arbor.

Pistons for petrol engines belong to the class of light thin-walled pistons which are able to retain functionality at high rotational velocities of engine arbor and under moderate pressures in a cylinder.

Pistons for diesel locomotives belong to the group of diesel pistons. “AVTRAMAT” produces three types of pistons for diesel locomotives.

Compressor pistons are characterized by relatively low load, thus they are made with thin-walled skirt and bottom. As a rule, compressor pistons are cylindrical.

The production of pistons in “AVTRAMAT” is not only industrial, but also scientific-industrial problem. In the course of constant improvement of the production, the enterprise develops and introduces science intensive solution based on the most modern trends of piston production industry.
