DIWA.6 – Less Consumption, Lower Emissions

Voith's DIWA.6 is our response to the increased demand for lower fuel consumption and lower emissions. The intelligent start-up management and the need-based reduction of the operating pressure reduce fuel consumption by up to 5%! That protects the environment with lower CO2 emissions. The newly designed housing and an optimized operating strategy ensure lower noise emissions.

Supplemented by the electronic E 300.1 control , the SensoTop topography-dependent gear-shifting program, the ALADIN diagnosis software and Stop-Start Technology, the DIWA.6 automatic transmission is the perfect example of an economical city bus transmission.

Another important characteristic of DIWA,6 is the need-based reduction of operating pressure. Full operating pressure is only produced if it is really necessary. This significantly increases transmission efficiency.
DIWA.6 combines the Automatic Neutral Shift ANS with intelligent start-up management: Sensors prevent the engine from working against the still-active brake during start-up and thus consuming unnecessary fuel.

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 to the reduced noise during stopping times. This expansion 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.
