The need to limit greenhouse gases emissions and to increase the share of renewable fuels in the general energy balance forces people to look for new alternative energy sources. Methane or biogas, in which methane is the main combustible component, is one of such fuels, which is believed to be a promising diesel engine fuel. It is worth emphasizing that biogas might be believed to be one of the cleanest fuels due to the fact that it can be produced from waste, which in normal conditions decomposes releasing methane into the atmosphere. Methane (biogas) combustion in diesel engines requires a dual-fuel feed system, in which the liquid fuel initiating auto-ignition will be injected into the combustion chamber. It comes as a consequence of a relatively high spontaneous combustion temperature of methane, which is not able to self-ignite in the chamber without an external source of ignition. This article presents a concept of constructing an integrated laboratory control system, which will provide optimal feed control of complex composition gaseous fuel and of the injection of an appropriate pilot dose of a liquid fuel into the combustion chamber. The solution proposed to control a dual-fuel diesel engine, which was mounted on the test bed, enables performing comprehensive diesel engine research, ensuring not only stable working conditions for the engine, but also granting an opportunity to smoothly regulate the composition of the artificial biogas which feeds the engine and to control basic parameters of the liquid fuel pilot dose.
