Abstract
Introduction (problem statement and relevance). Conversion of a reciprocating internal combustion engine (RICE) in order to use new fuels is accompanied by changes in power, economic and environmental characteristics. In the traditional approach when engine operating cycle calculating, the quantitative evaluation of influence of changes in the type and chemical composition of the fuel being used on power and economic parameters turns out to be difficult.
The purpose of the study is to obtain analytical dependencies for the quantitative evaluation of influence of chemical compositions of fuels – gases, alcohols and simple ethers – on charge and indicator parameters of the RICE operating cycle.
Methodology and research methods included thermodynamic analysis of gas exchange processes based on the ratios of partial or fractional volumes of the air-fuel mixture components.
Scientific novelty and results consist in the dependencies for taking into account the influence of chemical compositions and mixture formation methods on the engine power and economic parameters.
Practical significance consists in the quantitative evaluation of expected changes in the engine parameters when designing the engine or in case of conversion to a different type of fuel.
