【 摘 要 】

The paper presents results of investigation on a dual-fuel CI engine operating on natural gas, considering possibility to ensure durability of such operating engine comparable to that of a conventionally operating engine. During the investigation, comparable values of maximum combustion pressures and maximum rates of pressure rise were assured for both engine versions. To achieve the assumed objective, injection parameters of the pilot diesel fuel dose were adjusted. In result, the overall efficiency and main exhaust emissions of the engine operating in a dual-fuel mode were changed as well. Comparison of the described changes is presented in this paper.
