Description

In the dissertation, the efficiency of using Brown‘s gas (hydrogen and oxygen – HHO) in internal combustion engines where the gas is supplied into intake air is discussed upon. The principal subject of research is internal combustion engines operating on ordinary and alternative fuels with additionally supplied Brown‘s gas. The principal goal of the dissertation includes theoretical substantiation and experimental research of rationality of using Brown‘s gas in engines with compression and spark ignition upon taking into account the energy and environmental performance.

In the work, the following principal tasks are set: to investigate the energy efficiency of operation of the Brown‘s gas producing equipment, to examine the influence of the concentration Brown‘s gas in the combustible mixture upon the indicators of the working process in engines with compression and spark ignition and upon pollution of the fuel combustion products, to establish the impact of Brown‘s gas on fuel ignition in an engine with compression ignition.

The dissertation consists of the Introduction, three Chapters, generalization of the results, the List of references, the List of publications of the author related to the subject of the dissertation and four Annexes.

In the Introduction, the problem under research and its topicality are discussed upon, the subject of research is described, the goal and the tasks of the work are formulated, the methods of research, academic novelty of the work, practical importance of its results and the claims under defense are described. In the end of the Introduction, publications of the author and his reports at conferences related to the subject of the dissertation as well as the structure of the dissertation are presented.

In the Chapter One, review of literature is provided. It includes reviewing the factors in favour of hydrogen using as well as the methods for investigation on using hydrogen and Brown’s gas in internal combustion engines and the findings from such investigation. The conclusions from the Chapter are formulated and the tasks of the dissertation are closer specified. In the Chapter Two, the methodology for investigation on using Brown’s gas in internal combustion engines is provided. In the Chapter Three, the results of the experimental research on using Brown’s gas in engines with compression and spark ignition as well as digital simulation are provided.

Total 14 scientific papers related to the subject of the dissertation were published: six – in scientific journals cited in Inspec database, two of them – “ISI Web of Science” and eight – in other peer-reviewed journals. Total thirteen reports related to the subject of the dissertation were presented at conferences.
