    Operative estimating of diesel locomotive fuel consumption with its power unit mode mathematical model

    The article discusses the possibility of determining the specific fuel consumption of diesel locomotives in operation using indirect calculation methods based on the use of these locomotive onboard systems and supplementing them with mathematical models of the operating cycle and the model for determining the composition of the exhaust gases of a diesel engine. The basic equations and algorithms proposed for the implementation of such a method of mathematical models and the results of their use are presented, the results of a comparison of simulation results and experimental data on the specific consumption of fuel of diesel locomotives TEM18DM are presented. A possible algorithm for their joint use is proposed, conclusions are made on the possible development of such a method for determining the energy efficiency of diesel locomotives without taking them out of service.

    Calculation of combustion in the cylinder of a diesel engine that runs on gas-and-diesel cycle

    The article presents the method of calculating the amount of products of combustion of diesel fuel, gas-and-diesel and model calculations are made in relation to the diesel engine 16ЧН26/26 (2A-5D49). Parameters of the working cycle of a diesel engine operating on different types of hydrocarbon fuels, derived using a combination of methods Grinevetskiy-Mazinga and vibe. Calculation of the amount of harmful emissions and the amount of greenhouse gases is made using the method of equilibrium composition due to changes in the thermodynamic parameters and elemental composition of fuel burnup fuel mixture the positions of controller driver

    Feasibility study on application smesevs of types of fuel in diesel diesels

    The main direction of decrease in operational costs on draft of trains is reduction of expenses by fuel and energy resources, decrease in repair expenses at the expense of increase of indicators of operational reliability of power installations of a diesel rolling stock. It is obvious that the solution of these problems, now when operational profitability of diesels and their reliability are on a limit for the developed service conditions and production of diesel locomotives, it is possible at the expense of application of alternative types of the fuel which use will allow to raise both reliability of a diesel rolling stock, and its profitability under operating conditions. One of such alternative fuels can, is either natural gas, or household oil gas, that is a butane and propane mix in various ratios. In the present article on the basis of mathematical models possible ecological and economic efficiency of use of мix types of fuel on the example of the diesel 2A - 5D49 is shown.
