According to the mathematical model in the form of non-linear differential equations investigated the influence of compressibility factors and dynamic viscosity of diesel fuel by changing the pressure in the fuel system of a diesel engine with output.
The mathematical software computer aided design (CAD) of objects of production and transport infrastructure in timber industry (TI) is given, feature of which is the following. Tasks of establishing the optimal placement options of spur road on felling and loading points along it are solved together. At the next stage, the structural design of collapsible coatings of spur roads and topping hair-pin bend is made, if such coating is provided. Depending on the characteristics of accepted structures of the brain and deep sections of spur roads its length in the cutting area.
