The Performance Of The Car Under Test

Decent Essays

The analysis of the performance of the car under test was completed using AVL Cruise software. Various Graphs are obtained so that the actual performance of the car can be determined. Graph 1 (Abundance) prominently shows the torque of the engine at the respective engine speed along with the specific fuel consumption at that speed. Approximately 230Nm is the maximum torque that can be obtained at 4200 rpm, trailed by decrease in torque for the remaining speed. A cycle run was conducted for three different periods of cycle in which the vehicle was accelerated then hold and decelerated for certain time depending upon the requirement of cycle. Graph 2-A shows the change in velocity upon change in acceleration for three different cycle times. Also the shift of gears during the period can be observed. Graph 2-B illustrates consumption of the fuel during the three different stages. It can be noted that when the velocity was about 50 km/h the fuel consumption was about 5.0 l/h. Also it significantly notifies that during idling the fuel consumption is 1.6 l/h. In this Graph it can be inferred that the maximum operating pressure is 12 Bar for a speed of 4200rpm. Maximum fuel is consumed during the start of the engine at 0.5 bar, fuel consumption gradually decreases with increase in engine speed. Graph 3 speaks about the maximum operating pressure is 12 Bar for a speed of 4200rpm. Maximum fuel is consumed during the start of the engine at 0.5 bar and also between 0 bar and 1.6 bar at
