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.

Introduction.The paper is devoted to the investigation of the D-type diesel engines’ start-up of the B-2 type under low temperatures, especially to the influence of the fresh charge temperature on the starting characteristics of the diesel engines. The Russian Federation is located in climatic zones with predominance of low ambient air temperatures and under extreme conditions. However, such situation is not adequately studied in scientific literature.The main problem is in the search for rational values of the temperature of the fresh charge at the beginning of the compression stroke. The increase of such temperature leads to the decrease in the oxygen mass, and to the decrease to an insufficient temperature at the end of the compression stroke and, as a result, it would not provide ignition. Therefore, the aim of the research is to substantiate the rational values of the fresh charge temperature and further practical implementation of these values at modern BTWT facilities.Materials and methods.The author uses standard theoretical and theoretical methods based on widely approved dependences of the piston internal combustion engines’ theory, gas dynamics and thermodynamics, which have been refined taking into account the features of the diesel engine start. Results. As a result, the author determines rational values of the fresh charge temperature, makes the analysis of the pre-launch preparation and facilitating of the D-type diesel engines’ start-up and demonstrates the method of increasing and further stabilizing of the temperature of the inlet charge at modern BTWT facilities.Discussion and conclusion.The research confirms the rational values of the fresh charge temperature, by using of which the diesel has the best starting characteristics. The author also proposes a technical solution for values’ realization by using a vortex induction heater.

The paper discusses the application of an in-cylinder catalyst allowing a reduction of the exhaust emissions from a diesel engine. Its placement in the combustion chamber, the area where the process of combustion takes place, allows reducing the emissions (carbon monoxide, hydrocarbons, particulate matter) ‘at source’. The paper presents the possibilities of boosting the efficiency of catalysts in diesel engines by extending the time of heating of a glow plug (the catalyst applied on the glow plug). The tests were performed for the following conditions: no heating (marked 0+0), glow plug heating for 60 s after engine start (marked 0+60), glow plug heating prior to engine start for 60 s and glow plug heating for 60 s after engine cold start (marked 60+60). An improvement in the efficiency of oxidation of the exhaust components was observed as the glow plug heating time increased.

Cross-flow microfiltration (CFMF) has potentially wide application in the processing of industrial and domestic waste waters. Optimum design and operation of CFMF systems necessitates a knowledge of the characteristic system behaviour, and an understanding of the mechanisms governing this behaviour. This paper is a contribution towards the elucidation and understanding of the behaviour of a woven fibre CFMF operated in the turbulent flow regime. The characteristic flux-time curve and effects of operating variables on flux are presented for a limestone suspension cross-flow filtered in a 25 mm woven fibre tube. The phenomena contributing to the shape of the flux-time curve are discussed. A model of the mechanisms governing cake growth and limit is presented. Predicted steady-state fluxes show a notably good correspondence with experimentally measured values. It is also found that the flux may not be uniquely defined by the operating conditions, but may also be a function of the operating path taken to reach the operating point. This is of significance in the start-up and operation of CFMF units.

In order to reduce pollutants of the emission from diesel vehicles, complex after-treatment technologies have been proposed, which make the fault detection of diesel engines become increasingly difficult. Thus, this paper proposes a canonical correlation analysis detection method based on fault-relevant variables selected by an elitist genetic algorithm to realize high-dimensional data-driven faults detection of diesel engines. The method proposed establishes a fault detection model by the actual operation data to overcome the limitations of the traditional methods, merely based on benchmark. Moreover, the canonical correlation analysis is used to extract the strong correlation between variables, which constructs the residual vector to realize the fault detection of the diesel engine air and after-treatment system. In particular, the elitist genetic algorithm is used to optimize the fault-relevant variables to reduce detection redundancy, eliminate additional noise interference, and improve the detection rate of the specific fault. The experiments are carried out by implementing the practical state data of a diesel engine, which show the feasibility and efficiency of the proposed approach.
