Volvo Construction Equipment offers its L220F Hybrid wheel loader. Offering more power, better performance and a 10 percent reduction in fuel consumption, the L220F Hybrid’s system is made up of an ISG Integrated Starter Generator. Fitted between the engine and the transmission, the ISG is coupled to a state-of-the art battery that has many times the power capacity of a normal lead acid battery. The ISG works in a number of ways: Firstly, up to 40 percent of a wheel loader’s time can be spent with the engine idling. 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. Secondly, the ISG can also overcome diesel engine’s traditional problem of low torque at low engine speeds by automatically offering a massive electric torque “boost” as the ISG’s electric motor offers torque of up to 700 Nm from standstill. Put in engine power terms the ISG adds up to 50 kW of instant mechanical energy.
