City buses spend up to 40% of their operating time in idling mode. The new Stop-Start Technology from Voith for the DIWA.6 transmission offers an ideal enhancement for these stop-times. This technology, already established in the passenger car field, contributes considerably to reducing fuel consumption when used together with an engine that is equipped with the same function. Test results show a fuel savings potential of 10-12% (depending on application). The great advantage here is that this requires only a software enhancement, with no need to modify the design of the existing DIWA.6 transmission. The Voith DIWA.6 can achieve the spectacular value of up to 60 seconds shutdown time without any effect on start-up readiness. This technology is already in use in more than 100 vehicles in the UK and has been proving its capabilities and reliability very successfully since July 2015.
Benefits of the DIWA.6 Stop-Start Technology
In addition to more profitability due to the markedly reduced fuel consumption, the new and unique Stop-Start Technology for the Voith DIWA.6 transmission also offers a tangible added value to passengers, drivers and pedestrians thanks to the reduced noise during stopping times. This extension of our existing transmission leads directly to a reduction of CO2, NOx, particulate and noise emissions, which is a significant contribution to environmental sustainability. This enhancement of the DIWA.6 is an unparalleled and simple extension of an existing transmission for urban bus transportation, which increases the attractiveness of public transport, in addition to the economic benefits from the reduction of operating costs
