| 抄録（英） | The article is devoted to investigation of fuel supply control efficiency in a spark ignition engine equipped with a catalytic converter during use of ethanol-containing fuels with different ethanol content. The study involves determining the efficiency of fuel supply controlling algorithm for the engine, which is powered by conventional petrol and non-adapted for using fuels with high ethanol content. Within the study the following fuels were used: petrol, ethanol and fuel blends with ethanol content varying from 15 to 90%. The efficiency of fuel supply control is evaluated in terms of providing the specified fuel-air mixture composition, fuel consumption and emissions in transient engine operation modes during vehicle motion in the driving cycle. The data obtained during the engine bench tests using petrol and ethanol-containing fuels were used for evaluation. The data of the engine operation parameters measurements for transient vehicle motion modes under real road conditions are also used. Methods and experimental equipment are described. An original designed test device was used during the vehicle road tests. The device allows controlling the on-board diagnostic system data (OBD-II standard) at certain time intervals and parameters of satellite system of vehicle positioning (GPS standard), transmit this data by wireless communication to the information device on vehicle control panel and store them. For this purpose, the information device has an original author application for processing and storing the received data. Evaluation of the influence of the fuel supply controlling algorithm on the fuel consumption and emissions during use of different ethanol-containing fuels is carried out on the basis of vehicle performance in the driving cycle mathematical modeling. The description and features of mathematical model of the engine operating process are given. This model takes into account the available fuel supply controlling algorithm and ethanol content in the fuel. The dependencies of fuel consumption and exhaust gases emissions for the vehicle motion in the driving cycle using the studied fuel compositions, obtained using mathematical modeling, are presented. 翻訳 |
