BMW M54B22 Engine Specifications
The BMW M54B22 is a 2.2 liters (2,171 cc, 132.5 cubic inches) straight-six, four-stroke cycle naturally aspirated gasoline engine from BMW M54-family. The engine was manufactured oNmunich Plant (Munich, Germany) from 2000 to 2006. The engine features a cast-aluminum alloy cylinder block with cast-iron cylinder liners. The aluminum cylinder head uses chain-driven double overhead camshafts (DOHC) and four valves per cylinder (24 valves in total). It is equipped with a Siemens MS 43 engine management system, dual VANOS (Variable Valve Timing System from BMW) for both inlet and exhaust camshafts, fully electronic throttle without mechanical backup, dual length intake manifold (called “DISA” by BMW), a distributorless ignition system with individual ignition coils for each cylinder and an electronically controlled thermostat. An 80.0 mm (3.15 in) cylinder bore and 72.0 mm (2.83 in) piston stroke give the M54B22 engine a total of 2,171 cc (132.5 cubic inches) of displacement. Compression ratio rating is 10.7:1. This engine produced 170 PS (125 kW; 168 HP) at 6,100 rpm of maximum horsepower and 210 Nm (21.4 kgm, 154.8 ft-lb) at 3,500 rpm of peak torque.

| CYLINDER HEAD |
The cylinder head is made of an aluminum alloy with good cooling
efficiency. The M54B22 engine uses chain-driven double overhead
camshafts and four valves per cylinder. Standart head height is 140.0 mm
(5.5118 in). This engine is equipped with dual VANOS (Variable Camshaft
Timing) system. VANOS is fully variable and operates independently on
both intake and exhaust sides.
Intake valves are 30.0 mm (1.1811 in) in diameter and exhaust valves are
27.0 mm (1.063 in). Valve clearance is set by self-adjusting (zero-lash)
hydraulic lifters for reduced valve noise and the elimination of routine
valve adjustment.
