RATIONALE IMPROVE THE PERFORMANCE OF ECOLOGICAL DIAGNOSIS SYSTEMS OF DIESEL ENERGY INSTALLATIONS
Abstract
The analysis of the problem of increasing the duration and cost of procedures for environmental diagnostics of diesel power plants of different types as a result of introducing the mass emission of solid particles with exhaust gases into the composition of standardized parameters. Due to the insufficiently high rate of measurement of this indicator, the duration and cost of the procedure for the environmental testing of diesel engines significantly in-crease: using a single-filter method for the extraction of solid particles during the certification tests - in 1,2 ... 1,5 times, the multi-filter method during the research trials - in 1.9 ... 2.5 times.
In accordance with the requirements of the international standard ISO 8178, a method for accelerated measurement of this index is proposed and the expediency of its use is proved on the example of ecological certification and research tests of the main diesel locomotive 2ТЭ116 with the diesel unit 1А-5Д49. The proposed method is characterized by the maximum permissible filtration rate of a sample with solid particles of 100 cm / s and the minimum admissible masses of samples of solid particles that are collected on filters 0.25 mg and 0.14 mg using single-filtration and multi-filter methods for the extraction of particulate matter, respectively.
It has been established that compared to the most common methods of control of particulate emissions, which are realized in mini and microtunnels of firms Perkins, AVL, Mitsubishi, the method of accelerated metering is characterized by higher speed and economic efficiency of use - indicators that are of great importance for testing diesel engines high power - diesel, ship, etc. Application of the proposed method can reduce the duration, fuel consumption and cost of testing diesel engines: with certification tests - by 9 ... 28%, which is 0.2 ... 0.7 h, 25 ... 45 kg and 0.8 ... 1,5 thousand UAH for one test; at arbitrary tests - by 43 ... 53%, which for one test is 1.7 ... 3.0 h, 120 ... 225 kg and 4.0 ... 7.5 thousand UAH. When the actual emission levels of particulate matter with the exhaust gases of the diesel are reduced, the efficiency of using the proposed method is increasing.
Keywords: diesel, ecology, exhaust gases, particulate matter, microtunnel, accelerated measurement, rapidity.
