Piston
•
In accordance with the adoption of the common rail injection system, the piston head
shape now incorporates the combustion chamber. Due to the modified piston shape the
compression ratio is reduced from 21.6: 1 on the WLT-3 engine to 18.0: 1.
•
A reduction of the internal friction and hence of the engine’s mechanical loss has been
achieved by coating of the piston skirt area.
NOTE:
The piston side marked with ‘F’ must be installed towards the timing gear-side of the
engine.
