Low environmental impact engines

Zero emission sweepers

Thanks to its prestigious collaboration with the GORE® Group and intense research, Dulevo is proud to officially present a range of total filtering and zero emission road sweepers.

Forty years ago, when Dulevo took its first steps in the world of road and industrial cleaning, the central idea was to create a sweeping machine with innovative characteristics and technologies, offering a product incomparable to any other kind of sweeper present on the market at the time, for industries and local authorities. This is how the Dulevo patented mechanical-suction-filtering system was born.

Methane-powered road sweepers

Advanced research developed by Dulevo over the years as well as invaluable collaboration with independent research bodies and institutions, have led the company to become the only one in the world to fit fabric filters with a certified PM10 particle filtering level of over 99.9%.

Without resting on its laurels, Dulevo went on to transcend its own technological ambition, developing a methane-powered mechanical-suction sweeper.

Without compromising on sweeping performance, Dulevo succeeded in the creation of a new sweeper, inspired by the company's respect for the environment, city and citizens.

Major project features:

  • The use of natural gas drastically reduces emissions
  • All the most advanced technologies have been used to ensure installation is absolutely danger-free

The 6000 CNG and 6000 HYDRO CNG sweepers guarantee: minimum noise, zero emission of particles into the atmosphere, no polluting agents from the combustion of diesel or petrol used to power the sweeper, and the absolute certainty, truly for the very first time, of supplying local authorities with a zero emission machine.

The EURO6 engine: a new standard for the reduction of emissions

Many Dulevo sweepers can be fitted with a Euro 6 engine.

The exhaust gas post-treatment system HI-eSCR fitted in Euro 6 engines, uses clean air to maximise combustion efficiency and minimise particle production.
Exhaust gases are not recycled during this process, to reduce diesel consumption and increase performance.

The HI-eSCR uses a catalyst which chemically reacts with a water-urea solution (AdBlue) and converts NOx emissions into nitrogen and water vapour.

In addition, engines are also fitted with an electronically controlled exhaust valve, which ensures compliance with Euro 6 emission regulations.

This Euro 6 post-treatment system improves consumption, reduces installation complexity, while keeping vehicle maintenance requirements unaltered.
