Technical characteristics





Air filter and absorption channels

Soaked-up air contains particles of a dust and dirt which should not get to combustion chambers as they affect walls of cylinders as an emery paper. It would cause premature wear of pistons and directing cylinders. Therefore the air filter provides necessary protection of the engine. At the same time it extinguishes noise from air absorption.
