An investigation of crankshaft oscillations for cylinder health diagnostics
TL;DR: In this paper, the effects of cylinder imbalance on the individual harmonic components of the engine speed signal were investigated from a cylinder health diagnostics point of view. Butler et al. used a crankshaft vibration model to evaluate the effect of low power production in individual cylinders of a six-cylinder industrial diesel engine.
Spark Advance Modeling and Control
TL;DR: A new method to increase engine efficiency is presented, by using the closed-loop spark-advance control strategy in combination with active water injection and demonstrating that the controller maintains an optimal spark advance under various conditions and in the presence of environmental disturbances such as air humidity.
