Mechanical components
Introduction of the New V12 Biturbo Engine, M 279 AMG
b
The oil pan in model series 231 is a rear sump. The
upper and lower sections of the oil pan are
aluminum sand castings. To minimize noise, the oil
pan is decoupled from the crankcase by a vibration-
damping rubber seal.
The engine is supplied with oil by a 2-stage gear
pump,
which is d
riven by the crankshaft via a single
bush chain.
The oil sensor for measuring the oil level, tempera-
ture and quality is located in the rear of the oil
sump.
The oil sensor registers the oil level (capacitively)
and the
oil temperature (by means of a temperature
sensor). The quality is determined by measuring the
electrical parameters of the oil between two elec-
trodes. The measured values are digitally condi-
tioned and transmitted to the engine control unit.
