Introduction: The article analyzes the method of changing software electronic engine control units of a vehicle equipped with an LPG installation running on LPG. All LPG components are installed in certified workshops for cars, regular gasoline engines. Liquefied gas is used in automotive engines for many decades and is currently the most common type of alternative fuel.
Materials and Methods: At the Institute of mechanics and Energy of the National Research Ogarev Mordovia State University Department of technical service of cars was carried out on the programming of the electronic engine control unit staff installed on the car GAS-33027 for transfer of the vehicle engine to natural gas. It is necessary to make the change part of the data calibration tables for editing the software of the engine control unit, for optimum performance of the engine on LPG in the program of the ECU. WinOLS of EVC Electronic (Germany) and ChipTuningPRO of the SMS-Soft (Russia) were used in the research.
Results: We have changed the factory software version M124_AEC_03.41.152_10- 2013-R15 car GAS-33027 (GAZelle) after installing it on gas setting 4-th generation. Presents the results of changes in characteristics of fuel injection, namely the ignition timing at start-up and the optimal ignition timing of the regular and modified programs.
Discussion and Conclusions: The main advantages of the car equipped with LPG installation are fuel savings (cost of liquefied gas at 40–55 % cheaper than gasoline), the compactness of the installation of gas equipment, low equipment cost, no loss of engine power and resource.
