BMW engine diagram - BMW 3 (E46) engine M52TU (320i, 323i, 328i) diagram

1 - an ignition coil; 2 - the oxygen gauge; 3 - the catalytic converter; 4 - V belt; 5 - a clutch; 6 - the cooling fluid pump; 7 - a thermostatically controlled chamber; 8 - block VANOS; 9 - a hydropusher; 10 - cam shafts.
6-cylinder gasoline engine M52TU has a head of cylinders and the cylinder block from an aluminium alloy. The alloy has the improved heat conductivity and smaller weight in comparison with pig-iron. 4-klapannaja the head of cylinders has two cam shafts with a drive gear from a chain with the gear of regulation of cam shafts VANOS. Thus both cam shafts depending on number of revolutions and engine loading turn concerning a corresponding sprocket so that to receive the optimum moment of opening of valves. The knot is steered from an engine monitor.br>BMW engine diagram - M52TU engine parts diagram

In 4-cylinder turbodiesel М47 two cam shafts with the top arrangement have a chain drive gear and influence valves through a roller rocker actuator. The second chain actuates a high pressure fuel pump. A drive gear of valves - roller. The diesel engine has a turbo-supercharging with changeable geometry of the turbine (VTG) and cooling of submitted air. The head of cylinders is made of an aluminium alloy. The engine is supplied by the oxidising catalytic converter and system of recirculation of the fulfilled gases.
