Study on Engine Performance and Combustion System Optimization of a Poppet-Valve Two-Stroke Diesel Engine

open access: yesEnergies, 2022
Two-stroke engines have higher power density than traditional four-stroke engines, and therefore are suitable for engine downsizing. In this work, a four-stroke single-cylinder diesel engine is modified for two-stroke operation, and the combustion system
