A Study on the Comparison of Engine Performance and Vehicle Losses of a Gasoline Vehicle in WLTC and Artemis Rural Driving Cycles

Abstract

In this study, engine performance and vehicle energy losses of a passenger-type vehicle with a gasoline internal combustion engine were examined in 2 different driving cycles of the new generation with the help of the GT-SUITE vehicle simulation program. All parameters of the vehicle and the driving cycle were defined with the help of the simulation program. According to the simulation results, the number of gear changes and transmission losses were higher in the Artemis driving cycle, which had a higher average acceleration and deceleration acceleration, along with it. Torque converter losses were 4.73 times less in the Artemis cycle, where the torque converter locking clutch was used in greater quantities. The high average acceleration also increases tire and braking losses. When a comparison was made in terms of vehicle energy losses, it was found that Artemis driving cycle losses were 22% higher.
