Take A Look At The
Simple Design Of
The Engine. The
One-Piece Cylinder
Head Contains The
Overhead Camshaft,
Providing A Variety
Of Benefits:
■
Intake and exhaust passages are straight
for easy entry and exit of air from the
cylinder. The engine doesn’t waste fuel
“pumping” air in and out.
■
Intake and exhaust passages are also
short. Intake air is not overly heated as it
passes through the head. The resulting
cooler air in the cylinder improves econo-
my. And the hot exhaust gases don’t
transfer too much heat into the head as
they exit, saving more energy to operate
the turbo and increase fuel economy.
■
The overhead cam allows for direct actu-
ation of the fuel injectors without push
rods or push tubes. The result is high fuel
injection pressure and better fuel economy.
■
The overhead cam also allows for the use
of 38 head bolts, providing over 1,000,000
pounds of clamp load on the head gasket.
The cylinder liner is cooled all
the way to the top, using a
patented DDC feature called top
liner cooling. This reduces ring
temperatures by 100ºF, another
reason Series 60 engines live
so long.
Main and rod bearings are
big. That’s why the Series 60
engine has no requirement to
roll out bearings—it’s just not
necessary.
The Series 60 engine block,
with no camshaft, is a simple,
trouble-free design.
The Series 60 engine features
a high performance variable
output turbocharger for
improved low speed
performance, economy and
excellent driveability.
Another benefit is the Pad
Mounted Alternator System with a
Poly V belt and self tensioner. It’s
strong, rugged and simple.
Add the gear train to drive
the accessories and the
camshaft, and you have a
complete Series 60 engine.
