Capacidad y dimenciones de un VR6
Espero que les sirva para sus proyectos.
Components:
Blue indicates OE part.
Block:
"Vee" angle: 15°
Bore spacing: 65mm between cylinders.
Bore centerline offset from crank centerline: 12.5mm
Crankshaft:
2.8L Forged 90.3mm stroke
3.2L Forged 95.9mm stroke
Forged steel, six-throws, seven main bearings. Rod journals offset 22° from each other.
Rod journals are offset 22° to each other.
120° firing interval between cylinders.
Firing order: 1, 5, 3, 6, 2, 4
Connecting Rods:
164mm long, 657g w/o bearings, 20mm pin, 54mm bore
Forged Steel Rod, 164mm long, 578g w/o bearings, 20mm pin, 54mm bore
Ti Rod, 164mm long, 469g w/o bearings, 20mm pin, 54mm bore
Piston Assembly:
10 piston designs were tested during development by VW.
The result was a slanted piston head with an eccentric trough. The trough is offset from the center of the piston by 4.0 mm.
Compression gap height (at TDC): 1.5 mm.
Compression ratio: 10:1
Cylinder Head:
Cyl. 1, 3, & 5: short intake & long exhaust runners.
Cyl. 2, 4, & 6: long intake & short exhaust runners.
Valvetrain:
Intake 39.0mm
Exhaust 34.3mm
Other:
The difference in port length is compensated for in the intake manifold.
Intake runners are 420mm long.
Fuel pressure is regulated depending on intake manifold pressure.
The injectors are 12v and are grounded through the Motronic ECU.
They operate sequentially in the cylinder firing order.
volume is determined by the injector opening time.
If no signal from the air mass sensor, the signal from the throttle pot. is substituted.
Crank sensor: 60-2, records RPM and w/ Hall signal locates TDC for #1 cyl.
Knock sensor I (G61) monitors cylinders 1,2,and 3.
Knock sensor II (G66) monitors cylinder s 4, 5 and 6.
With the Hall signal, the ECU can determine which cylinder is knocking. The ignition angle of the knocking cylinder is retarded in steps until the knocking stops up to a maximum of 12°.
If spark knock is still detected, the ECU will retard the ignition timing 11° for all cylinders and record a fault.
