CUTAWAY DIESEL ENGINES

CATERPILLAR 3600 SERIES

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 than metal.

**********

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).
