The article presents a mathematical model of a distributorless ignition system used in internal combustion engines. The proposed model was used to analyze the values of individual structural components of the ignition system. Laboratory and operational test results of the ignition system components were used to develop the mathematical models. A computer analysis of the system was performed based on a proprietary program implemented in the Delphi environment.An analysis of the change in high-voltage cable resistance values was performed to determine the voltage and current values at the spark plug.
The operation of an internal combustion engine depends on the correct functioning of the ignition system, as the combustion process in the engine and, consequently, power, torque, fuel consumption, and exhaust toxicity depend on the spark discharge energy and the ignition advance angle.
The conducted research aims to optimize spark discharge parameters to achieve the assumed engine performance effects. (…)
