Abstract

The main power source of modern electric start systems for internal combustion engines is an acid-lead battery. Existence chemical reactions, which occur in between battery electrolyte and lead plates may be causes problems with it exploitation. For a many reasons, its operation requires a lot of labor, especially in cold conditions. In this regard, it was proposed to use a capacitor system electric supply taking in view its discharge characteristics. Electrolytic capacitors and supercapacitors are sources of temporary charge storage and have optimal properties for their use in the engine start system as a partial displacement of the acid-lead battery, against the background of its some negative qualities. The article deals with the evaluation and comparison of the electric motor start system from capacitors and supercapacitors, as well as the possibility of their implementation on a mobile machine equipped with ICE.

Highlights

In most cases of vehicles such as tractors and automobiles, a starter motor with an electric power source feeding it is used as a starting system for the internal combustion engine
Such a system is controlled via a relay or additional electronics from the ignition switch and has an overall efficiency of 50-70% [1]. This is primarily due to the flow of high currents, heating of wires, high mechanical moments of resistance in the flywheel drive system, slowing down the flow of chemical reactions occurring in the battery, especially in cold conditions, while operation processes prevent crankshaft to spin up [2,3]
Difficult start-up in cold conditions is a consequence of a decrease chemical process velocity and result the battery capacity, as well as inrush currents, and is a frequent problem in the operation of such systems [4,5]

Summary

Introduction

In most cases of vehicles such as tractors and automobiles, a starter motor with an electric power source (acid-lead battery) feeding it is used as a starting system for the internal combustion engine. Discharge of the acid-lead battery, count of cycles increases to only 4000...7000, which is still less than the capacitors, so it justifies their use in the system for start the engine.
