DESCRIPTION

Introduction

The Cummins 5443112 Engine Crankshaft is a vital component in the engine systems of heavy-duty trucks. Manufactured by Cummins Inc., a renowned leader in the automotive industry, this crankshaft is designed to meet the demanding requirements of commercial and industrial applications. Its robust construction and precise engineering contribute to the overall performance and reliability of the engine 1.

Basic Concepts of Engine Crankshafts

An engine crankshaft is a mechanical part found in internal combustion engines. Its primary function is to convert the linear motion of the pistons into rotational motion, which drives the vehicle’s wheels. This conversion is achieved through a series of crankpins and connecting rods that are strategically positioned along the crankshaft. As the pistons move up and down within the cylinders, the crankshaft rotates, transferring power to the transmission system 2.
