Abstract :
The middle speed four stroke diesel engine has the advantages of small capacity, light in weight, capable to combustion poor fuel oil. In recent years, they have been used more comprehensive than before. Daihatsu 6PSHdM-26H diesel engine, which is a type of 4-stroke medium-speed turbocharged marine diesel engine, is widely used in ocean-going ships. Describes the failure or fuel injection system with low-grade heavy oil led to increased delayed combustion and exhaust temperature will affect the flow characteristics through the engine, changes in diesel engine with turbocharger and running line is the surge caused by an important reason. Considering its working principle and structural properties, this paper establishes its physical and mathematical models in order to set up the numerical calculation method, gets the relative parameters of increased delayed combustion. On the basis of the numerical calculation of air cooler, these results not only provides some theory support to solve deteriorated of operational performance for heavy-duty 4-stroke marine diesel engine, but also decrease the dependence degree for a marine engineer, then make it possible to scientific manage modern big-scale automatic engine room and improve the reliability of marine trust power plant.
