Diesel and/or electric drive
Its 4.5-litre PACCAR FR diesel engine naturally complies with the ultra-low EEV emission requirements. It offers a maximum power of 118 kW/160 hp and is linked to an automatic Eaton six-speed gearbox.
Between clutch and gearbox is the electric motor which provides drive as well as a generator function. Energy released during braking is stored in special lithium-ion batteries for re-use during acceleration.
A central computer determines when the diesel engine provides the drive and when and to what extent the electric motor is used.
In total, the DAF LF45.160 Hybrid is some 300 kilograms heavier than the standard model with only a diesel engine. Because the DAF LF series is famous for its favourable kerb weight, the 12-ton LF Hybrid still offers a large payload of some 7.5 tons.
When the hybrid battery pack is fully charged, the LF Hybrid truck can travel about two kilometers electrically and without the need of the diesel engine.
In practice, this is enough for driving in and out of the “green zones” in city centers. In circumstances such as these, the diesel engine remains at idle in order to drive various components, such as the steering pump and the air compressor.
The LF Hybrid is also equipped with a start/stop system for zero fuel consumption and zero emissions when the vehicle is stopped.
Longer parts service life
Another advantage of hybrid technology is that components susceptible to wear, such as brake pads and clutch plate, will have a longer service life because braking is generated by the electric motor.
