Determination of the Quantitative Characteristics of the Engine of a Household Power Plant when Using Generator Gas as an Alternative Fuel

Abstract

The relevance of the study is due to the need to study the feasibility of replacing traditional fuel with alternative types (generator gas) when using a household power plant. The purpose of the study is to obtain the value of a small-displacement engine GG-2700 with a working volume of 1563 cm3 when it works on commercial fuel (gasoline) and generator gas. For this purpose, the authors developed an experimental setup on the basis of a small-sized household power station with fixation of variable parameters on a personal computer and a graphical representation of the measurement results. The records of the indicator diagrams allowed determining the burning time of various fuels. As a result, for the first time, there were obtained quantitative indicators of fuel efficiency and toxicity of exhaust gases of the small-displacement engine GG-2700 with a working volume of 1563 cm3 when using commercial fuel (gasoline) and generator gas. The analysis of the data showed an increase in the specific consumption of generator gas in comparison with gasoline from 34.6% to 50.4% and a decrease in the content of toxic components in the exhaust gases: carbon monoxide (CO) – in 1.05 ... 1.25 times, hydrocarbons (CxHy ) - in 1,1 ... 1,39 times, nitrogen oxides (NOх) - in 3,9 ... 5,7 times. The obtained results prove the expediency of using generator gas as an alternative fuel for the engine of a household power plant.
