Caterpillar 3612 Diesel Engine
This page has been set aside for shots of Caterpillar's
fabulous 3600 series cutaway display engine. This engine was photographed
in close quarters so there was not enough room to show the entire
engine, which is cut away in various ways through several cylinders.
As a result we are showing it in photos that show smaller areas
of the engine. This machine is fabulous, it is so nicely painted
that it looks like it is made of bright molded plastics rather
This view through across the lower
portion of the block shows the crankshaft and connecting rods
(blue), the oil passages (red), the air intake manifold (blue)
and the cooling water passages (green).
This view of the upper area of
the block shows the aftercooler housing at the top, which provides
intake air to the distribution manifold in the center of the vee
of the engine. The cylinder on the left is sectioned through the
intake passage (blue) and the cylinder on the right is sectioned
through the exhaust passages (red).
This cylinder is sectioned through
the exhaust passages (red) and shows the coolant jacket around
the liners (green). This cylinder has all three of the rocker
arm sets, for the exhaust valves (closest), the injector (middle)
and the intake (farthest back).
This cylinder has been sectioned
through the intake valve side (blue) , and only shows one cam
follower and rocker arm set, for the intake valves.
Here is another cylinder bore area
in the engine adjacent to a central separation, this area is cut
close to engine structure and displaying the water passages that
would be around the outside of the cylinder liner. This engine
is quite outstanding in having many cylinders in the engine sectioned
differents way to show a wide variety of details.
The turbocharger of the display
engine is sectioned to show the oil passages, the bearings, the
rotating assembly, and the passages in the housing for air (blue),
exhaust (red) and water (green).
