DEVELOPMENT OF AN ELECTRONIC CONTROL SYSTEM FOR GAS-ENGINES, CONVERTED ON THE BASIS OF TRANSPORT DIESELS TO WORK FOR ON LIQUEFIED PETROLEUM GAS

Abstract

The expediency and advantage of using gas motor fuels on a relation to traditional liquid motor fuels is shown. Technical solutions for the use of gas motor fuels by diesel engines are presented and analyzed. On the basis of the analysis, the expediency of converting diesel engines into gas engines with forced ignition is justified.An electronic microprocessor control system for gas internal combustion engines with forced ignition has been developed, which has a modular structure consisting of two main and a number of additional subsystems. The structures are described and the principle of operation of the main subsystems is described, including LPG injection subsystem, as well as the ignition control subsystem. An experienced ECU was developed and created. A structural scheme of the electronic control system of a gas engine with an experienced ECU is given. The out motorized tests of the experienced ECU were carried out, which confirmed his operability.
