• NEW PISTONS - The piston has a shorter skirt compared to the M52 TU and continues
with the graphite coating for friction and emission reducing measures. The piston rings have
been modified to reduce friction.
• CRANKSHAFT - The crankshaft for the 3 liter M54 is adopted from the S52B32 - M3
engine. The crankshaft for the 2.5 liter is carried over from M52.
• CAMSHAFT - The camshaft for the 3 liter M54 is modified with more lift (9.7 mm) and
new valve springs to accommodate the increased lift. The camshaft of the 2.5 liter M54 is
carried over from the M52 engine.
• INTAKE MANIFOLD - The intake manifold is modified with shorter ram tubes (20mm
shorter on 3 liter/10mm shorter on 2.5 liter). The diameter of the tubes is increased slightly.
• INJECTION VALVES - The diameter of the injection pintle has increased slightly for the
increased displacement of the 3 liter engine. The injector for the 2.5 liter engine carries over
from M52.
NON RETURN FUEL RAIL SYSTEM
The M54 engine with MS 43.0 control uses the non return fuel rail system introduced on
the M62 TU engine. The system meets running loss compliance without the use of the 3/2-
way solenoid valve currently used on the M52 TU engine.
The regulated fuel supply is controlled by
the fuel pressure regulator integrated in
the fuel filter. The fuel return line is also
located on the filter.
The M54 engine uses an Electronic Controlled
Throttle Valve (EDK) for intake air control. The
idle control valve and turbulence function of the
intake manifold carries over from the M52 TU
engine.
