Diesel engine; Super-capacitor; Starter system; Modeling; Simulation Abstract. In order to improve the start-up performance of the diesel engine and the working conditions of batteries, make efficient use of the high instantaneous discharge power characteristics of the super-capacitor as a diesel engine start-up auxiliary power. Taking the YC6J180 types of Yuchai diesel engine as illustration, diesel engine starting process was modeled and simulated by Matlab/Simulink software, and compared with the simulation model of diesel engine starting system added the super-capacitor. The simulation results show that the diesel engine starter system added the super-capacitor as the auxiliary power, the starting performance is improved significantly, meanwhile improve the battery state, and extend its service life.

In order to reduce loader engine installed power and save energy, we designed the driving scheme of power system for parallel hybrid loader by Analysis of different way of connection between diesel engine and electric motor. We chose ISG power electric multifunction and super capacitor as the core component to design the Loader auxiliary power system and movable arm cylinder gravitational potential energy recovery system. We established ADVISOR software model of hybrid power Loader, and the simulation results show that diesel engine installed power of the hybrid power Loader is reduced by 21%; fuel consumption is reduced by 9.2%. Through optimize control strategy, the diesel engine can always working in high efficient area or idle area. Practical application shows that this design scheme has the potential economic and environmental benefits.

We demonstrate the detailed analysis for conversion of piezoelectric properties into compliance matrix and simulate a series bimorph configuration for vibration based energy generation. Commercially available software COMSOL Multiphysics was used to apply boundary conditions for optimization of geometric parameters such as length, width and thickness of piezoelectric layer to study voltage and power characteristics of the harvester. The resulting energy harvester was found to generate 1.73 mW at 53.4 Hz across a 3MW load with an energy density of 13.08mJ/cm3. We also investigated feasibility of this model by comparing it with existing experimental data of known piezoelectric ceramic compositions and found good correlation between the two.

This article discusses the measures for efficient use of fuel and energy resources in the railway industry. The calculation of the initial moment of starting the diesel engine and the necessary position of its crankshaft is made, on the basis of which it is proposed to modernize the locomotive start-up system with a decompressor. These measures are aimed at reducing the dynamic loads of engine components and reducing their wear and tear, as well as failure preventing. A method for the clean-up of fuel systems and the cylinder-piston diesel engine group of diesel locomotives was developed and tested using a special cleaning liquid that dissolves and removes solidified particles from pipelines and tanks. Measures have been proposed on the use of advanced models to test the modernized locomotives that will reduce the duration of the tests, resource and economic costs. The use of advanced testing model involves choosing the level of accuracy of the test results and, consequently, their duration and cost.
