with the Di Pietro engine

01 COMPACT

Our engines diameter is not much bigger than a flip out mobile phone; yet has sufficient force to power a car. A single engine can power a 600kg car.

02 LIGHTWEIGHT

This small engine weighs little more than a bag of potatoes (6 kg) and has no more than 10 major components.

03 EFFICIENT

Our engine achieves a mechanical efficiency of 90% and delivers constant torque with virtually no friction. Only 1 PSI (≈ 6,8 kPa) of pressure is needed to overcome the friction.

EngineAir's Environmentally Friendly solution

We have developed an efficient and environmentally friendly rotary engine that has the capacity to provide stationary and mobile applications with all necessary power and torque; without any combustion fuel or toxic batteries.

We use clean compressed air as fuel, which is sustainable, and affordable.

Learn HOW it works

The cylindrical shaft driver, forced by the air pressure on its outer wall, moves eccentrically, thereby driving the engines shaft by means of two rolling elements mounted on bearings on the shaft. The rolling motion of the shaft driver inside the stator is cushioned by a thin film of air. Timing and duration of the air inlet and exhaust is governed by a slotted timer which is mounted on the output shaft and rotates at the same speed as the engine.

Variation of performance parameters of the motor is easily achieved by varying the time during which the air is allowed to enter the chamber: A longer air inlet period allows more air to flow into the chamber and therefore results in more torque. A shorter inlet period will limit the air supply and allows the air in the chamber to perform expansion work at a much higher efficiency. In this way compressed air (energy) consumption can be exchanged for higher torque and power output depending on the requirements of the application.

Engine speed and torque are simply controlled by throttling the volume or pressure of air into the engine. The Di Pietro engine gives instant torque at zero RPM and can be precisely controlled to give soft start and acceleration control.

O2 Pursuit

The "O2 Pursuit" compressed air-powered motorbike has been designed by RMIT industrial design student Dean Benstead. Instead of a regular petrol powered engine, the O2 Pursuit uses our engine.
