METHOD TO LIMIT SMOKE AND FIRE WHEN LOADING A DIESEL ENGINE

摘要

A method for limiting smoke and fire upon loading a diesel engine having a power piston with a variable piston gap for controlling fueling of the engine, includes sensing the piston gap value on a cyclical basis, computing the piston gap velocity, comparing the computed piston gap velocity with a preset piston gap velocity range, and adjusting engine horsepower output upon the computation of an abnormal piston gap velocity reading. Thus, engine overfueling during loading is prevented.
