Volvo L220F Hybrid Wheel Loader

Sept. 28, 2010

 

Volvo Construction Equipment says the L220F Hybrid wheel loader is the first of its kind in the world, and the machine will offer 10 percent fuel savings as well as performance and environmental gains. The heart of the parallel-hybrid system is an Integrated Starter Generator (ISG) fitted between the Volvo D12 engine and transmission. The ISG allows the diesel engine to be turned off when stationary, and then almost instantly restarted by rapidly spinning the engine up to optimum working speed using a burst of energy from the high power battery. The ISG can also deliver a massive electric torque boost — up to 700 Nm and 50 kW of instant mechanical energy — to overcome the diesel's low torque at low engine speeds.
