The analysis of scientific investigations makes it possible to make a conclusion about the usefulness of the generator gas as a fuel for internal combustion engines of mobile power generators. Under the conditions of agricultural production and in rural areas, the generator gas can be generated from biomass (wood, straw, corn stalks and other plant refuse). The paper recommends to use a gasifier of the reverse process for gas generation. The side of the recovery zone of the gasifier is 200 mm long, and the recovery zone is – 70 mm high. The number of tuyere holes is 20, the diameter of the tuyere holes is 10 mm. The research was conducted in order to determine the effects of the produced generating capacity on generator gas and air consumption, as well as on emissions of greenhouse gases (CxHу and CО). The paper shows the nature of the effects of the produced generating capacity on generator gas and air consumption by the engine of a mobile power generator. As follows from the investigation, under the generating capacity, which corresponds to nominal electric generator charge, under the use of generator gas generated from wood CO emission is up to 25 times less, and CxHу emission is up to 9 times less as compared to gasoline fuel. While using the generator gas generated from straw, CO emission is up to 25 times less, and CxHу emission is up to 4 times less as compared to gasoline fuel. The paper also shows the results of the investigation as to the impact of the engine exhaust supply of a power generator engine into the combustion area of a gas generator on the power generator schedule, as well as on the dynamic pattern of the generated effective power.
