RESEARCH AND ASSESSMENT OF THE FUEL ECONOMY OF CAR USING A 7 SPEED AUTOMATIC TRANSMISSION WITH HYDRAULIC VARIOUS

Abstract

This article utilizes MATLAB - SIMULINK software [5] to investigate and evaluate the fuel economy of automobiles through the vehicle's powertrain system, specifically for vehicles using hydraulic systems, with calculated parameters equivalent to a 2.0-liter passenger car [2]. The computational results indicate the fuel consumption and travel distance of the vehicle at gear ratios 5, 6, and 7, at power levels of 40 kW, 60 kW, and 80 kW. The outcomes of this study will serve as a basis for calculating, designing, testing, and comparing power transmission systems, thereby assisting operators in selecting the most reasonable modes to ensure maximum performance and minimal fuel consumption.
