Environmental control of the technical condition of electromagnetic nozzles of internal combustion engines

Abstract

Harmful motor vehicle emissions are often the primary source of urban air pollution worldwide. Incorrectly serviced high-mileage motor vehicles emit significantly more harmful substances into the atmosphere than established by accepted standards. This paper presents an algorithm for the process of diagnostics and analysis of the technical condition of the fuel supply system elements for internal combustion engines (ICE) by means of selective sampling of exhaust gases. A gas analyzer system allows for the simultaneous monitoring of the 4 components of exhaust gases: CO, CH, O2 and CO2, assessment of the air-fuel ratio and internal combustion engine crankshaft rotation speed. Studies were carried out on an engine and a series of malfunctions were created artificially, by means of installing faulty elements and additional elements simulating different degrees of wear on the ICE systems. The study resulted in the development of a method and a hardware and software system. These allow for the test regimes to be established, in order to determine the failure of ICE systems which affect the composition of the exhaust gas.
