CYLINDER BLOCK |
The 3VZ-FE engine has 6 cylinders in a V arrangement at a bank angle of
60 deg.. This engine’s firing order is 1-2-3-4-5-6. The crankshaft is
supported by four bearings inside the crankcase. These bearings are made
of copper and lead alloy. The crankshaft is integrated with semi 9
counterweights for balance. Oil holes are placed in the center of the
crankshaft for supplying oil to the connecting rods, pistons and other
components. Crankshaft main journal diameter is 64.000 mm (2.52 in) and
crankpin diameter is 55.000 mm (2.16 in)
Pistons are made of high temperature-resistant aluminum alloy, and
depression is built into the piston head to prevent interference with
the valves. Piston pins are the full-floating type, with the pins
fastened to neither the piston boss nor the connecting rods.
Each piston is equipped with two compressions and one oil control rings.
The top compression ring is made of steel and the second compression
ring is made of cast iron. The oil ring is made of a combination of
steel and stainless steel. The outer diameter of each piston ring is
slightly larger than the diameter of the piston and the flexibility of
the rings allows them to a hub the cylinder walls when they are mounted
on the piston.
Bore is 87.5 mm (3.44 in) and stroke is 82.0 mm (3.23 in). The
compression ratio rating is 9.6:1.

CYLINDER HEAD |
The cylinder heads are made of aluminum alloy, with a cross-flow type
intake and exhaust layout and with pent-roof type combustion chambers.
The spark plugs are located in the center of the combustion chambers.
The 3VZ-FE engine has double overhead camshafts DOHC design with four
valves per cylinder (two intake and two exhaust valves). The intake
camshafts are driven by a single timing belt, and a gear on the intake
camshaft engages with a gear on the exhaust camshaft to drive it. The
camshaft journal is supported at five (intake) or four (exhaust) places
between the valve lifters of each cylinder and on the front end of the
cylinder head.
The intake valves are 34.0 mm (1.34 in) of diameter, while the exhaust
valves have a diameter of 27.3 mm (1.07 in). The intake duration is
230°, the valve lift is 7.85 mm, and the exhaust duration is 230°,
valve lift is 7.60 mm;. Exhaust and intake valves are equipped with
irregular pitch springs made of special valve spring carbon steel which
are capable of functioning no matter what the engine speed.
Adjustment of the valve clearance is done by means of an outer shim type
system, in which valve adjusting shims are located above the valve
lifters. This permits the replacement of the shims without removal of
the camshafts.

Valve clearance adjustment data
Calculate the thickness of the new adjusting valve shim so valve
clearance comes within specified values.
R = Thickness of removed valve shim
N = Thickness of new valve shim
M = Measured valve clearance
Intake:
N = R + [M - 0.20 mm (0.008 in)]
Exhaust:
N = R + [M - 0.30 mm (0.012 in)]
Valve shims are available in 17 sizes to range from 2.50 mm (0.0984 in)
to 3.30 mm (0.1299 in), in steps of 0.05 mm (0.0020 in).
Example (exhaust valve):
R = 2.70 mm
M = 0.52 mm
N = 2.70 + (0.45 - 0.30) = 2.85 mm.
