Assessment of the influence of design and regulatory parameters on the level of harmful emissions in the exhaust gases of a medium-speed diesel engine

Abstract

Strategies for selecting and combining tools for solving problems of improving the environmental friendliness of diesel engines are considered. Modeling of changes in the ratio of fuel consumption and nitrogen oxide emissions based on the 12ЧН26,5/31 engine with a power of 4400 kW produced by JSC "Kolomensky Zavod" is carried out. The proposed strategy can be used during development tests of experimental engines. Keywords dividing grid method, measurement errors, extrusion, channel, section, widening extrusion
