1-19. ENGINE SYSTEM OPERATION

The Caterpillar 3116 engine has a 403 cu. in. (6.6 L) displacement, with 4.13 in.

(105 mm) bore and 5.0 in. (127 mm) stroke. The engine is a four-stroke cycle, in-line

6 cylinder with direct fuel injection. The engine is turbocharged with an air-to-air

aftercooler (ATAAC) system, and is rated 170 hp at 2700 RPM.

The engine lubricating oil, which is both cooled and filtered, is supplied by a gear-

type pump. Bypass valves provide unrestricted flow of lubrication oil to the engine

parts when oil viscosity is high, or if either the oil cooler or the oil filter elements

should become clogged.
