Lubes and Digits

摘要

Engine control modules can adjust a diesel's performance almost continuously, communicating with not only the engine components but also with other machine systems, such as hydraulics. These tweaks increase fuel efficiency and manage torque, giving the machine operator finer and finer control over the work being done. Underneath, however, it's still fuel injected into cylinders that must smoothly fire and return while bathed in a film of lubricant functioning at high temperatures. Although digital information has been overlaid, the basic physics remain the same.
