Differences between naturally aspirated engine and turbocharged engine
| Engine 266.920/940/960 (naturally aspirated engine) | Engine 266.980 (turbocharged engine) |
|---|---|
| Oil pressure switch (S43/1) for measurement of the engine oil operating pressure | Oil pressure switch (S43/1) for measurement of the engine oil operating pressure and high oil pressure switch (S43/2) for measurement of the turbocharger oil pressure |
| Variable intake manifold with variable intake manifold switchover valve (Y22/6) | - |
| Pressure sensor (B28) for measurement of the absolute pressure in the variable intake manifold | Pressure sensor (B28) for measurement of the absolute pressure in the charge air distribution pipe |
| - | Pressure sensor downstream air filter (B28/5) for measurement of the ambient pressure in the charge air intake pipe between the air filter and the turbocharger. |
| - | Pressure sensor upstream of the throttle valve actuator (B28/6) for measurement of the charge air pressure before entry in the charge air distribution pipe |
| - | Pressure sensor in the ME control unit (N3/10) for measurement of the absolute pressure and for altitude adaptation. |
| - | Turbocharger with boost pressure control pressure transducer (Y31/5), divert air switchover valve (Y101) |
