Function
Charge air flows into the combustion chamber of the cylinder when the intake valves (7) are open.
The injector (3) injects fuel into the combustion chamber creating an air/fuel mixture which ignites sponta-
neously under compression.
When the exhaust valves (9) open, exhaust gas created by the combustion process flows via the outlet duct
to the exhaust manifold leading to the exhaust turbochargers. The valve gear opens and closes the intake
and exhaust valves (7, 9).
