Model-based on-board post-injection control development for marine diesel engine

Speed Control System on Marine Diesel Engine Based on a Self-Tuning Fuzzy PID Controller

The degree of speed control of ship machinery effects on the economics and optimization of the machinery configuration and operation. All marine vessel ranging need some sort of speed control system to control and govern the speed of the marine diesel engines. This study presents a self-tuning fuzzy PID control system for speed control system of marine diesel engine. The system under considerat...

Adaptive Model Predictive Control of Diesel Engine

Study on the Testing Method for Marine Diesel Engine

For the high-power low-speed diesel engine’s performance and reliability evaluation, this paper studies the engine’s running-in norms, presents the Test Scheme about the combustion process, the Inlet swirl control, the cooling system control, and the distribution and emission. The whole engine’s test methods and systems are established. By using the combined method of the test platform research...

Semi-physical mean-value NOx model for diesel engine control

In this paper, a new physics-based model for the prediction of NOx emissions produced by diesel engines is presented. The aim of this work is to provide a Mean-Value Model (MVM) adapted for control design and online estimation. The proposed approach is based on the simplification of a zero-dimensional thermodynamic model. Only the main phenomena taking part in NOx formation are kept and they ar...

A dynamic PCCI combustion model for Diesel engine control design

Subject of this work is a dynamic simulation model for PCCI combustion that can be used in closed-loop control development. A detailed multi-zone chemistry model for the high-pressure part of the engine cycle is extended by a mean value model accounting for the gas exchange losses. The resulting model is capable of describing PCCI combustion with stationary exactness. It is at the same time ver...
