Abstract

The paper dwells on peculiarities of operation of engine running on gaseous fuel that envisages the influence of the period of impeding spontaneous combustion on the operation of engine with the dependence on dosing of fuse. Simultaneously, there is considered the influence of changeability of the air-excess coefficient on the engine load when using the different gaseous fuels, as well as its influence on the efficient operation of engine, improvement of ecological and economic parameters, with account for improving geometrical parameters of engine. There are given the analysis and comparison of the efficient characteristics of the ideal cycle of diesel engine when running on liquid and gaseous fuel.
