Justification for the Conversion of a Combine Harvester to Operate on Compressed Natural Gas


The article considers the issue of expanding the use of gas motor fuel in the agricultural sector on agricultural machinery. Several regulatory documents on the regulation of relations in the use of gas motor fuels and on energy conservation and energy efficiency in agriculture are indicated. It was noted that the conversion of agricultural machinery, in particular, combine harvesters to compressed natural gas, has been little studied and little attention has been paid to this, although this area is promising, especially for the Tyumen region of Russia, since it has huge reserves of natural gas. The use of natural gas as a motor fuel on a combine harvester is more expedient than the use of liquid fuels, since such gas is a more economical, safe, environmentally friendly and environmentally friendly type of fuel. An Acros-530 combine harvester was chosen as the object of study. The purpose of the study is to increase the efficiency of the combine by converting it to work on gas fuel. The technical characteristics of the gas engine Yaroslavl Engine Plant-53644 CNG, which is proposed to be used instead of a regular diesel engine, are considered. Analysis of the design of the Acros-530 combine allowed us to determine the place for placing gas cylinders, as well as the mounting points of the developed frame designs on which gas cylinders will be mounted. It is planned to install 9 cylinders with a capacity of 276.9 cubic meters on the combine. m compressed natural gas. An analysis of the technological operations of grain harvesting using a gas processor showed the possibility of achieving an annual economic effect for a field of 1,500 hectares of more than 100,000 rubles, mainly due to a reduction in fuel costs by 3.5–4.5 times.
