Combustion in an incinerator occurs in two dif­ ferentiated zones: (1) the solid bed, Zone I, where the principal processes are pyrolysis, gasification, and combustion, and (2) the overbed region, Zone II, where the principal processes are flame holding and final burnup. Equations are developed to relate com­ bustion intensity in each zone independently to the average combustion rate in each zo...

Diesel engine emission standards are being more stringent as it gains more publicity in industry and transportation. Hence, designers have to suggest new controlling strategies which result in small amounts of emissions and a reasonable fuel economy. To achieve such a target, multi-objective optimization methodology is a good approach inasmuch as several types of ...

One of the important problems in reducing pollutant emission from diesel engines is trade-off between soot and NOx. Split injection is one of the most powerful tools that decrease soot and NOx emissions simultaneously. At the present work, the effect of split injection on the combustion process and emissions of a direct-injection diesel engine under full-load conditions is investigated by the c...

homogeneous charge compression ignition (hcci) combustion is a pioneer method of combustion in which pre-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. hcci engines can operate with most alternative fuels, especially, dimethyl ether (dme) which has been tested as a possible diesel fuel due to its simultaneously low nox and pm emissions. in this paper a sin...

The combustion mechanisms of clouds of metal particles are addressed in this research. A microgravity environment was used to create a “stationary model aerosol” consisting of relatively large (100–300 mm diameter), initially motionless particles. The development of individual particle flames, motion of individual particles, and overall aerosol combustion process could be observed simultaneousl...

Cylinder pressure simulation has grown to become an important tool when developing and evaluating new engine concepts and control strategies. A new formulation of zero-dimensional multi-zone models is developed and described. A general model structure is formulated that rely on a set of differential algebraic equations that are easy to solve. The selected formulation also results in models that...

The latest electronically controlled marine engines have a control system that allows the operator to view all essential parameters of engine in real conditions during operation. is connected electronic (ECS) through network, thus controlling engine. has various management and monitoring options. objective this paper was become familiar with specific factors affect operation optimize A model la...
