The converter has a mechanical clutch (lockup), which, when the load is stable, locks the
converter pump mechanically.
2.4 Plan of experimental work
In order to prove the efficiency of lock up system, a plan for experimental works has been
prepared. An identification of lock up system’s influence on machine operation in real environment was the main target. We would like to check if the usage of the lock up system
affects:
• Fuel consumption
• Averaged speed of machine during transporting materials
• braking performance of the engine
