History

BMW M62 V8 Engine

From 1994 to 2005

 BMW M62 V8 Engine From 1994 to 2005
 
The BMW M62 is an eight-cylinder V engine from BMW and the successor to the M60 engine range. The engines were produced from 1996 to 2005 and installed in the BMW models 8er E31 , 7er E38 , 5er E39 and X5 E53 . Furthermore, they were as in  the Range Rover from Land Rover , Bentley Arnage  and in the Morgan Aero 8 used. The most significant changes to its predecessor were the capacity expansion and the introduction of the variable camshaft control VANOS in the TU version. The S62B50 engine of the BMW M5The E39 series and the Z8 are based on this range of engines.

The BMW M62 is a V8 DOHC piston engine which replaced the M60 and was produced from 1994 to 2005. Compared with its M60 predecessor, the M62 features Alusil cylinder liners (in markets where high sulphur fuel was sold) and a single row timing chain. In 1998, variable valve timing (called VANOS by BMW) was added to the M62.

Design

The M62 engine block is made from Aluminium with Alusil or Nikasil cylinder liners, depending on the country of intended sale.

The M62 is fitted with Sequential fuel injection and double overhead camshafts with 4 valves per cylinder. It also sports fracture-split forged connecting rods.Variable valve timing is fitted to the later "M62TU" variants.

S62

The S62 engine (also known as S62B50) is a high-performance variant of the M62 which is fitted to the E39 M5 and E52 Z8. It is enlarged with a bore of 94 mm (3.7 in), a stroke of 89 mm (3.5 in) and a displacement of 4,941 cc (302 cu in). It shares its basic architecture, including aluminium block, with the M62 engines.

Previous M5 engines were assembled at M division headquarters in Garching, Germany but the S62 M5 engines were assembled at the Dingolfing assembly plant.

Eight individual throttle bodies (one per cylinder) control the airflow into the engine, these throttle bodies are electronically actuated (often referred to as "drive-by-wire"), with a setting for the driver to select "normal" or "sport" mode throttle response. Bosch Motronic version MSS 52 is used to control fuel injection, ignition timing and other functions.

Variable valve timing is used for both the intake and exhaust camshafts; the S62 was the first BMW V8 engine to incorporate this feature. The compression ratio is 11.0:1 and hollow camshafts are used.While the M62 engine uses a single-row timing chain, the S62 uses a double-row timing chain.

The S62 engine produces 294 kW (394 hp) at 6600 rpm and 500 N·m (369 lb·ft) at 3800 rpm. The redline is 7000 rpm.
