On the Issue of Electric Starter Start Systems with Alternative Current Sources

In recent years, much attention has been paid to the use of capacitive energy storage devices (ES) as sources of electrical energy in electric starter start (SES) systems of an internal combustion engine (ICE). The conducted experimental studies show that the process of starting the SEP internal combustion engine with ES is significantly different from the start-up process when the starter motor (SEM) is powered by a rechargeable battery (B). In a number of works [1], [2], experimental studies of the processes of scrolling the VAZ-21073 automobile engine when powered by high-voltage ES with different values of the initial charging voltage were carried out. However, this issue has not been practically investigated, there are no recommendations on the choice of the initial charging voltage of the ES, which makes it difficult to manufacture such systems. This article presents the results of a theoretical study on the effect of the value of the initial charging voltage of the ES on the main characteristics of the SES for automotive internal combustion engines equipped with standard SEM. In this case, the initial data are the starting and mechanical characteristics of the internal combustion engine, the type of SEM, its nominal operating characteristics and the total active resistance r., the gear ratio of the drive from the SEM to the ICE. The starting characteristics of the internal combustion engine at different temperatures are determined experimentally and represent the dependence of the start time tp on the average rotational speed <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$n$</tex> of the crankshaft.
