Abstract
Abstract The estimation of pollutant emissions from a mobile diesel generator for starting aircraft engines recorded the following qualitative composition of the exhaust gas mixtures from the aircraft: CO, NO x (total NO 2 and NO), C, CH (total hydrocarbons), SO 2 , CH 2 O, C 20 H 12 (3,4-Benzpyrene). An analytical calculation was made from a stationary diesel generator of maximum and gross emissions of individual i-th pollutants. A quantitative assessment of pollutant emissions from racing tests of aircraft engines on bench measuring systems has been implemented. An analytical calculation was made of the characteristics: the amount of i-pollutants during the take-off and landing cycle, departing from the aircraft, gross emissions for 2 types of engines ICE-1 and ICE-2, and the most sold for bench runs of aircraft engines. The calculation of the maximum one-time amount of pollutants emanating from a source of pollution into the atmosphere is fixed taking into account the limiting factor - by the maximum emission concentration, this is for ICE-2. It was established: analytical calculations for the second test site recorded that, during control diagnostics of the operability and reliability of aircraft power plants on bench measuring systems, nitrogen oxides and carbon monoxide also prevailed in emissions from engines.
