Abstract:
The paper presents the preliminary tests for a new method of controlling diesel injection at the injector of a compression
ignition engine. The purpose of the paper is to verify the possibility of obtaining certain quantities of fuel, sprayed by
injector by this method. It was also verified the possibility of changing the value amount of diesel sprayed by injector
according to certain parameters. Unlike conventional injection systems, in this method the injector receives the fuel
from an electrically operated piston pump element via an electromagnet. The entry into service of the electromagnet is
controlled by an electrical circuit equipped with a capacitor battery. The capacitor battery is designed to store electricity
and restore it to the action control of the electromagnet. In this way, the actuation time of the piston pump element is
very short. The opening time of the injector can also be easily modified. The tests presented in the work are carried out
using a prototype, which has been tested only on a stand designed by the author and not on a running engine. At this
preliminary testing stage it was followed whether the proposed method allows fuel injection through the injector. It was
also monitored if there was a possibility of changing the dose of injected fuel. It was looked which of the constructive
and functional factors influence the modification of the injected dose.
