Abstract A simple and unified index is proposed to achieve knock detection under various engine loads. Maximum amplitude vibration oscillation (MAVO) maximum pressure (MAPO) were compared found have no consistency. This means that MAVO cannot accurately reflect knocks inside the cylinder in time domain. However, a knocking built with can effectively detect loads, which implies some important information connected may be hidden within it. In this circumstance, frequency domain analysis...
To improve the dynamic response speed of high-speed solenoid valves in electric fuel injection systems marine diesel engines, a numerical simulation model valve is described this paper. The accuracy was verified on test bed valve. effect punch position and size were investigated by using distribution law electromagnetic force armature. results showed that armature drilling inter-yoke zone can optimize closing time, but it has little impact opening time. From rule, two groove schemes further...
The structure and performance of the common-rail system for marine diesel engine are different from those used automobile applications, resulting larger accumulator volume single injection volume. According to characteristics distributed volume, a novel optimisation idea improve steady-state high-pressure fuel designed retrofitting is proposed. study concentrates on in hydraulic layouts parameters manage energy stored pressure waves. First, test rig was established evaluate system. Second,...
Abstract As the critical components for marine low-speed diesel engine flue gas waste heat recovery (WHR) supercritical carbon dioxide (S-CO 2 ) Brayton cycle system, structure of compressor impeller is optimized by evolutionary algorithm (EA) based on co-simulation CAESES, ANSYS CFX and Opti Slang. The law pressure ratio, efficiency power consumption in S-CO (SCBC) as a function rotational speed, inlet temperature, structural parameters are revealed, method improving SCBC studied. greatly...
Modern diesel engine systems rely more and on electronic control systems. The benefits of such include reduced fuel consumption, limited emissions enhanced performance. Following the trend, this article aims to derive an appropriate methodology for improving performance speed regulation by upgrading existing mechanical governing system one marine engine. Hardware-in-loop simulations test-bed experiments are applied realize a V-type mode study strategies medium-speed engines. First, algorithm...
The match of an injector with the combustion chamber was studied through computational fluid dynamics simulation under four different engine loads. Four design parameters including start injection, spray angle, protrusion length and swirl ratio were examined. Latin hypercube together a non-linear programming by quadratic Lagrangian algorithm used in optimisation. Comparisons made loads terms optimisation history, objectives, sub-objectives parameters. commonalities optimums summarised....
