The valve timing mechanism serves to ensure the intake of fresh air charge into the cylinders and the exhaust of exhaust gases from them
The system of gas turbine supercharging and charge air cooling, by using part of the energy of the exhaust gases, provides the supply of pre-compressed and cooled air to the engine cylinders
The cooling system is designed to ensure optimal thermal conditions for engine operation
The fuel supply system filters the fuel and distributes it evenly among the engine cylinders in metered portions at strictly defined moments
