z
are positioned so that their tips direct fuel just ahead of the engine intake valves.
z are connected in series with the fuel pressure sensor.
z supply fuel from the fuel tank with a fuel pump mounted in the fuel tank.
A constant fuel pressure drop is maintained across the fuel injectors by the fuel pressure sensor. The
fuel pressure sensor:
zis positioned upstream from the fuel injectors on the fuel injection supply manifold.
Valve Train
The valve train operates as follows:
zball- tip hydraulic lash adjusters provide automatic lash adjustment.
z roller followers ride on the camshaft lobes, transferring the up-and- down motion of the
camshafts to the valves in the cylinder heads.
Positive Crankcase Ventilation System
All engines are equipped with a closed- type positive crankcase ventilation system recycling the
crankcase vapors to the upper intake manifold.
Lubrication System
The engine lubrication system operates as follows:
zoil is drawn into the oil pump through the oil pump screen cover and tube in the sump of the oil
pan.
z oil is pumped through the oil bypass filter on the left front side of the cylinder block.
z oil enters the main oil gallery where it is distributed to the crankshaft main journals and to both
cylinder heads.
z From the main journals, the oil is routed through cross- drilled passages in the crankshaft to
lubricate the connecting rod bearings. Controlled leakage through the crankshaft main bearings
and connecting rod bearings is slung radially outward to cool and lubricate the cylinder walls as
well as the entire connecting rod, piston and piston rings assembly.
z The left cylinder head is fed from a drilling into the supply passage feeding the main gallery at
the front of the cylinder block. The right cylinder head is fed from a drilling into the rear of the
main gallery. Main gallery pressure is reduced as it enters the cylinder head galleries through
fixed serviceable orifices located at the upper part of the feed passages. It is this reduced
pressure in the cylinder head galleries which feeds the camshaft journals, the hydraulic lash
adjusters and the primary and secondary timing chain tensioners.
z The camshaft lobe and roller followers are lubricated by splash created through valve train
operation.
Oil Pump
The lubrication system of the 4.6L (4V) engine is designed to provide optimum oil flow to critical
components of the engine through its entire operating range. The heart of the system is a positive
displacement internal gear oil pump using top seal rotors. Generically this design is known as a gerotor
pump, which operates as follows.
zThe oil pump is mounted on the front face of the cylinder block. Klj . 2 ba
