Co-relation Between Engine Test Bed Data and Vehicle Level Data to Generate Duty Cycle for Commercial Vehicles 2008-01-0696

Duty cycles are useful in development of vehicle. Duty cycle is the percentage of time the vehicle is operating at different percentage of load. A methodology has been established to derive a duty cycle for commercial vehicles according to real life data.
Correlation between engine test bed data (engine rpm, quantity of fuel injected, torque) and vehicle data (engine rpm, quantity of fuel injected) through INCA software has been established using MATLAB programming. The same correlation is proven successfully by actual measurement of torque on propeller shaft with the help of Strain gauges and SOMAT instrument. This simulated cycle is used to find out fuel consumption on engine test bed itself. Results show that the duty cycle based fuel consumption on engine test bed matches with real life data.
