EngineAir develops an air driven burden carrier for Melbourne Market Authority

The Di Pietro motor, developed by Engineair in Brooklyn, Victoria, offers an outstanding reduction in air consumption compared to conventional air motors, and together with its high torque capability makes a mobile application such as the market burden carrier technically and economically feasible.

The carriers are powered by the energy stored in compressed air.
The compressed air is held in tanks mounted under the loading floor.
Engineair will develop a new burden carrier, driven by compressed air for use at the Melbourne Wholesale Fruit & Vegetable Market. The Melbourne Market Authority has offered Engineair a grant to develop and build a prototype for a new carrier driven by a compressed air motor.

The air drives the air motor without any combustion or exhaust gases, which makes this a zero-pollution mobility concept ideal for enclosed areas such as the market or factories and warehouses.

“Engineair Takes Air Technology To A Higher Level”

The Di Pietro air motor excels in performance and versatility over the drive technologies. The high torque at low RPM, air consumption efficiency, low weight and financial benefits including low capital and maintenance cost render the Di Pietro motor a feasible alternative in many applications.

This Versatility opens up opportunities for new market development beyond the reach of current air motor technology due to their operational or economic performance.

The Di Pietro motor concept is based on a rotary piston. Different from existing rotary engines, the Di Pietro motor uses a simple cylindrical rotary piston (shaft driver) which rolls, without any friction, inside the cylindrical stator. The space between stator and rotor is divided in 6 expansion chambers by pivoting dividers. These dividers follow the motion of the shaft driver as it rolls around the stator wall. The motor shown is effectively a 6 cylinder expansion motor.
