Difference in a design of engines of type TU3 and XU the insignificant.
In engine TU3 of a support of the main necks of a cranked shaft form one uniform (as the bottom part of the block of cylinders of the cranked shaft divided on an axis) whereas in engine XU of a support of the main necks of a cranked shaft fasten separately (the block of cylinders indivisible). Therefore and a method of hermetic sealing of a cranked shaft another.
In engine TU3 valves in a head of the block of cylinders are established at an angle and in this connection bilaterial levers of valves whereas in engine XU valves are established vertically act and put in action directly through pushers.
In engine TU3 other contour of oil system in comparison with engines XU. |
