Application of the Miller cycle to the diesel engine to improve its environmental performance — •Yuriy Kochanov — Russia, Moscow

This work demonstrates the application of the Miller cycle to the diesel engine 12FB26,5/31 to improve its environmental performance. Two methods of implementing the Miller cycle, "early" and "late," are investigated, and the choice of one method is justified. IVC and EVO angles are selected to implement the chosen method of the Miller cycle. The problem of reducing engine power during the implementation of the Miller cycle is solved by compensating with increasing of the degree of pressure increase in the compressor. Gas recirculation is applied in conjunction with the Miller cycle. Gas distribution phases, degree of pressure increase in the compressor, and degree of recirculation are selected using numerical modeling in a one-dimensional approach. All parameters are selected through single-factor or two-factor optimization based on emission of harmful oxides and particulate matter. As a result of this work, the engine's operating process meets environmental requirements for emissions of NOx, SOx, CO2, and emission of solid particles. This research was made in the Strategic Academic Leadership program.
