Some aspects of the use of natural gas motor fuel in diesel locomotives

Вестник Научно-исследовательского института железнодорожного транспорта, 2020
Due to the increase in the cost of diesel fuel, much attention is paid to the use of alternative types of fuel on diesel locomotives. Variants of using fuel obtained from coal, plants, gas fields and hydrogen are considered.

Effect of Cylindrical Turbulators on the Mixing Process in Basic Venturi Gas Mixer Using OpenFOAM

MATEC Web of Conferences, 2019
This study was devoted to improving the mixing quality in a Venturi gas mixer. It is well known that the performance of industrial gas engines strongly depends on the quality of air and fuel mixture and therefore on its homogeneity.

Investigations on Air-Fuel Mixture Formation for industrial Gas Engines

KNOCKY Symposium, 2019
The main task of a gas mixer is to mix the fuel (gas) with air in such a way that in the gas engine optimal combustion takes place. A high efficiency and low emissions are the decisive optimization parameters, according to the applicable regulations.
