Atlas test world’s first hybrid-power loader

The world's first hybrid wheel loader has been developed by heavy plant maker Atlas-Weyhausen in conjunction with engine maker Deutz of Germany.

Earmarked for production in 2010, the new machine is said to reduce fuel consumption by up to twenty per cent while reducing harmful emissions accordingly.

Unlike hybrid cars, the vehicle starts and runs normally on conventional power. However, when a load is placed on the engine, electric motors are engaged and are used for drive. The diesel engine itself has a sophisticated motor-generator fitted where the flywheel would normally be fitted. 

Constantly energized when the engine is running, the hybrid system creates electrical energy which is stored in a battery pack.

The makers claim that the electric boost can provide the non-turbo diesel with enough power to effectively double output and reduce fuel consumption by as much as a third.

Although a novelty at the moment, hybrid plant and construction vehicles are likely to become commonplace as stringent new legislation aimed at cutting carcinogenic soot particles come in to force around the globe over the next five years.
