Abstract

Annotation. Introduction. Currently, the issue of fuel efficiency, emissions regulation of harmful substances and the search for alternative fuels is especially relevant. The choice of natural gas for an engine as an alternative to traditional fuels imposes its limitations, which can be avoided by applying the Miller cycle.

The purpose of the study was to determine and compare the potential for improving 6ChN13/15 diesel engine converted for an energy efficient duel-fuel engine operating according to the Miller cycle with early closing of the intake valve and the engine potential of Otto thermodynamic cycle.

Methodology and research methods. The research was carried out by a natural experiment method.

Scientific novelty and results. A comparative analysis of various experimental results studies of engines thermodynamic cycles running on natural gas has been carried out. The results obtained will be used to create and further optimize a duel-fuel engine by controlling its workflow and the air supply system.

Practical significance. The indicators results of Otto engines and engines operating according to Miller's thermodynamic cycles with early closing of the intake valve have been compared. The results obtained may be of interest to truck manufacturers and engine specialists.
