The engine burns diesel fuel within its cylinders, converting the chemical energy of the fuel into mechanical energy that turns the central output shaft. Early locomotives used resistors to control the current sent to the traction motors, resulting in significant energy loss as heat.
Diesel Locomotive Mechanical Components Overview
This configuration provides superior control, reliability, and starting torque, making it ideal for the demanding tasks of railroading. This process efficiently converts the mechanical rotation into alternating current (AC) electricity.
Dynamic Braking: A Smart Use of Energy When the engineer applies the brakes, the process is remarkably efficient. Instead of connecting the engine directly to the wheels through a complex gearbox, the locomotive employs a diesel engine that drives an electrical generator.
Diesel Locomotive Mechanical Components Overview
Understanding how a diesel locomotive works reveals a sophisticated system where diesel engines drive electric generators, creating a unique and highly efficient method of rail propulsion. Control and Regulation: The Electrical System The true brilliance of the diesel-electric system lies in its control mechanism.
