Abstract
The purpose of this paper is to describe the design, development, and performance aspects of the Caterpillar 3176 diesel engine. The 3176, named for its displacement (1.7 liters per cylinder) and the number of cylinders (6), is a four-stroke-cycle, in-line engine with electronically controlled unit injection, turbocharging and Air-to-Air AfterCooIing. The 10.3 liter (629 in3) displacement engine was developed primarily for heavy duty on-highway truck applications, and will initially have power ratings from 187 kW to 242 kW (250-325 hp) at 1700 to 2100 rpm. This paper highlights several of the engine's design features which reduce fuel consumption, emissions, size and weight, while providing performance and durability characteristics comparable to larger displacement engines.
