Real-time simulation of two-stroke marine diesel engine

Based on Quasi Steady State Method, a multi-order nonlinear model of marine diesel engine suitable for Marine Engine Room Simulator (MERS) is formulated, which allows to simulate the dynamics of diesel engines with a relatively simple model. The whole engine system is divided into several functional blocks. The sub-models of individual blocks and the dynamic model of engine system are established according to engine working principles and experimental data. Some empirical equations describing the transient performance of engines are proposed to simplify the modeling. The real-time simulation of a container ship's main engine-MAN B&W 6L80MC low speed two-stroke turbo-charged diesel engine is presented as an example.
