The Ural Diesel Engine Plant (UDMZ) has developed a new multi-cylinder V-shaped diesel engine with two-stage turbocharging and a modular design. The power unit received 16 cylinders and a cylinder bank angle of 60 degrees.
The main feature is the transition to a modular scheme. UDMZ engineers moved the turbochargers and charge air coolers to separate platforms.
This solution reduces the number of assembly operations from 31 to 21, and the number of components in the boost system decreased by 53 positions.
The engine received two-stage gas turbine supercharging. Air first passes through the first-stage turbochargers, then cools, after which it is directed to the second stage with repeated cooling. This scheme allowed increasing the power of each cylinder by 23%.
Compared to previous solutions, the weight of the structure decreased by 221 kg. For heavy diesel generator sets, this can mean simplified layout and increased unit life.
