Abstract

Biogas is an alternative source of energy, now it can also be used as a motor fuel for gasoline engines of internal combustion with spark ignition. This article describes the biogas obtained by processing cattle manure. The obtained biogas was enriched and compressed to the level of natural gas. A schematic diagram of the experimental test bench for the study of automotive biogas engine is given. A description of the measuring instruments used in this experimental test bench is shown. In this paper, the task is to create an automated test bench for the study of the workflow of the engine, which works on biogas. To select and justify the parameters of the workflow, a full range of instrumentation is needed, which satisfies the following requirements: the ability to work on gasoline and biogas; the ability to control the composition of the working mixture, both when working on gasoline and biogas; the possibility of forced control of the value of ignition advance angle; measurement of the moment of resistance on the motor shaft in the whole range of rotational speed variation (n = 800…5590 min-1); registration of pressure in the engine cylinder (indicator diagram) with the subsequent determination of indicator characteristics; registration of air and fuel consumption; maintaining a stable temperature mode of the engine. In addition, an automated research system should provide for the collection of experimental data for on-line processing and for the collection of a database. The use of biogas as a fuel for gasoline internal combustion engines will save natural resources and improve the ecological and economic status of the Republic of Sakha (Yakutia) and whole Russia.
