Electronic Fuel Control For Small Diesels: Woodward APECS 4800 system designed to provide greater precision than mechanical controls

摘要

The Woodward APECS 0154 LAPS (linear actuator with position sensor) actuator works with the APECS 4800 controller to accurately control fuel flow on small diesel engines. For several decades, mobile industrial and stationary diesel engine applications have used mechanical governors to control fuel pump output. While traditional injection pump technology offers a proven, reliable, low-risk means of delivering the proper amount of fuel to the engine, the mechanical governors that control them can be limited in terms of precision and functionality. Electronic solutions continue to grow in popularity as manufacturers look for simple, lower-cost ways to add precision fuel control to small diesel engines.
