Abstract
MATHEMATICAL MODEL OF DETERMINATION OF CONCENTRATION OF CARBON GAS IN EXHAUST GASES OF AUTOMOBILES Averyanov V.S., Shmatko D.Z., Sasov O.O., Kochneva O.V. Abstract Cars are moved by means of a power unit - an internal combustion engine. During operation, the engine burns fuel. Depending on the type of fuel burned, the air flow rate factor and the type of engine, the combustion of the fuel can occur with the formation of products of complete and incomplete combustion. With complete combustion of the fuel, the combustion products consist of the following components: carbon dioxide CO2, water vapor H2O, excess oxygen O2 and nitrogen N2. If there are sulfur compounds in the fuel, the combustion products contain sulfur oxides SO2 and SO3, which are classified as harmful emissions. Nitrogen oxides in the exhaust gas usually contain NOx and NO2, which are also harmful to the environment. With incomplete combustion, combustible gases can appear in the combustion products of the fuel: carbon monoxide CO, hydrogen H2, methane CH4, and sometimes hydrocarbons CmHn. In recent years, the problem of environmental protection has become increasingly important. In order to find ways to reduce air pollution, a large number of complex studies are being carried out. The success of such studies largely depends on the ability of gas analysis to determine the concentration of various harmful emissions in combustion products and industrial emissions. The aim of the work is to develop a mathematical model for determining the concentration of carbon monoxide in the exhaust gases of cars.The study used the exhaust gases of the petrol engine of ZAZ Forza. The content of harmful substances in the exhaust gases of cars depends on the operational modes of the car (the speed of the crankshaft, the speed of the car and the load on the car). To construct a mathematical model for determining the concentration of carbon monoxide in the exhaust gases of cars from the above factors in the form of a first-order polynomial, the methods of planning the experiment were used, namely, a complete factor experiment. The obtained mathematical model allows to determine the concentration of carbon monoxide in the exhaust gases of cars, depending on the operating conditions of the car (the speed of the crankshaft, the speed of the car and the load on the car).
