A Test Method for Individual Control of the Engine’s Ecological Parameters

Abstract

Abstract An analysis of the state-of-the-art has shown that the dominating number of failures falls at internal combustion engines (ICEs): the ignition system - 15-25%, the power system -30-44%, the exhaust system - 10-15%. It follows from the analysis of modern ICE configurations that the most applicable ICE control method is a selective control method with a subsequent individual adjustment for the current technical condition. The combination of a gas analyzer installed individually in each collector, a motor tester and a test mode former with the function of ensuring test modes allows us to identify failures of the three systems with a high accuracy and to assign an individual corrective action to ensure the specified ecological and economic parameters. A small percentage of throttle opening reliably reflects the information on the mechanical and electrical parts of the injector, matching of the mixture formation and the combustion process at minimal toxicity. In case of a large percentage of throttle opening, the data on the injector section, operation of the ignition system on a rich mixture and significant outlet resistance is informatively reflected.
