Abstract
This paper deals with the use of the internal combustion piston engine, which is a drive unit for micro-cogeneration units. The introduction is a brief statement of the nature of gas mixture compositions that are useful for the purposes of combustion engines, together with the basic physical and chemical properties relevant to the burning of this gas mixture. Specifically, we will discuss low-energy gases (syngases) and mixtures of natural gas with hydrogen. The second section describes the conversion of the Lombardini LGW 702 combustion engine that is necessary for these types of combustion gases. Before the experimental measurements, a simulation in the Lotus Engine simulation program was carried out to make a preliminary assessment of the impact on the performance of an internal combustion engine. The last section of the paper presents the experimental results of partial measurements of the performance and emission parameters of an internal combustion engine powered by alternative fuels.
Highlights
In the current development of combustion engines, there is a trend to put emphasis on performance and cost parameters, and on environmental parameters, the aim being to achieve the most acceptable values
The experimental results showed that the torque of the engine in operation with H2NG15, compared to natural gas (H2NG0), was on an average 2 % lower, which on an average meant a decrease of 0.8 N·m
Mixtures of natural gas and hydrogen have a major advantage over other types of fuels for powering internal combustion engines: they produce lower exhaust emissions, unburned hydrocarbons, namely carbon monoxide and carbon dioxide
Summary
In the current development of combustion engines, there is a trend to put emphasis on performance and cost parameters, and on environmental parameters, the aim being to achieve the most acceptable values. A mixture of natural gas and hydrogen will above all be used to drive vehicles in urban areas, where there are higher requirements on complying with emission regulations. This mixture combines the advantages of the individual components of the mixture. A combination of this natural gas with oxygen to power internal combustion engines can achieve multiple benefits in terms of combustion and emissions:. The second fuel types that will be used for powering internal combustion engines in cogeneration units are called synthesis gases. These gases are derived mainly by gasification of wastes. The rest of this paper these fuels (H2NG0, H2NG15, SYNGAS 1 and SYNGAS 2) will be used to drive a Lombardini LWG 702 internal combustion engine, and the parameters will be evaluated
