Accurate, stable and reliable lubrication for the cylinders is very important to ensure trouble-free operation of marine diesel engines. A new electronically controlled cylinder system has been developed remedy defects conventional mechanical system. This system’s design method, composition implementation are described. The sensitivity tests conducted on test bench verification also fulfilled operating vessels. main performance data as follows: oil injection pressure about 3.0 MPa, timing...
Lubrication of cylinders between liners and rings is one the crucial factors that affects efficient operation diesel engines. Marine engines usually use inferior heavy fuel oil with high sulphur content, acidic substances formed by combustion need alkaline cylinder to neutralize. For operational cost a marine engine, besides oil, also takes big share. This article first analyses advantages disadvantages existing lubrication systems regard injection control. Second, control parameters...
The common rail pressure of a marine diesel engine high-pressure system is typically controlled by PID (Proportional Integral Differential) algorithm, which has problems with both overshoot and response delay. In this paper, the control method based on object model for studied. established within controller. Through developed current actual obtained real-time acquisition, variables issued controller to are predicted calculated. fuel supply required in whole calculated advance, then taken as...
In this paper, the high-pressure common rail system of marine diesel engine is taken as case study to establish a real-time simulation model that can be used controlled object control system. On premise ensuring accuracy, should also respond quickly instructions issued by The development based on modular modeling method, and divided into submodels, including oil pump, tube, injector, mass conversion. submodels are built using “surrogate model” which mainly composed MAP data empirical...
In this paper, based on the characteristic analyzing of mechanical fuel injection system for marine medium-speed diesel engine, a sectional high-pressure common rail is designed, rated condition pressure which 160MPa. The simulation model built and performance high analyzed, research results provide technical foundation engineering development.
This paper takes a marine low-speed engine as the research object and establishes cylinder liner-piston ring lubrication model based on time-varying supply characteristics of lubricating oil. By changing oil injection position, film thickness, distribution range, etc., control parameters are controlled analyzed. Influence performance ring. The results show that when feed rate is 1.0 <tex>$\mathbf{g}/\mathbf{kW}\cdot \mathbf{h}$</tex>, point located 1.5 m above bottom dead center piston,...
In order to improve the economic performance and knock suppression of natural gas-diesel dual-fuel engine, cylinder pressure control technology based on self-adaptive piston (PSAP) was studied. The engine working process model established in AVL-BOOST, dynamics Matlab/Simulink, dual-model coupling realized. simulation results show that: PSAP can effectively pressure, increase maximum burst 8.12 MPa under 25% load conditions, reduce 13.82 100% conditions; cyclic fluctuation, compared with...
