The Volvo L220F Hybrid offers higher efficiency, reduced fuel consumption and a lessened impact on the environment.
Volvo Construction Equipment (Volvo CE) unveiled a pre-production prototype of its L220F Hybrid wheel loader during CONEXPO-CON/AGG 2008 in Las Vegas.Offering more power, better performance and a 10 percent reduction in fuel consumption, the L220F Hybrid's increased efficiency and cost savings potential will offer the end user a much greater return on investment over the lifecycle of the machine.The Volvo L220F Hybrid's parallel hybrid technology has been developed within the Volvo Group and uses the D12 engine. While much of the technology remains confidential, the heart of the hybrid system is 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 provides the end user with power only when it's needed. With the ISG, the diesel engine can 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. Another feature of the ISG is that it can overcome the 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.Deliveries are estimated for late 2009.
