It might not seem that way as you fill up on your way to work, but the petroleum used to make it is gradually running out. Automobile manufacturers know all of this and have spent lots of time and money to find and develop the fuel of the future. The search is on, but what will this fuel of the future be? Ready-made fuels like petroleum are becoming more difficult to find and automobile manufacturers are turning to greener energy sources like batteries.
The invention has the capacity to revolutionise transportation, plus offer a multitude of energy-saving benefits in stationary applications. The engine has no emissions, is very quiet, has constant high torque, a low parts count, no vibration and Air powered engine very Air powered engine - only 1 PSI of pressure is needed to overcome the friction to enable movement.
As my engineering business was doing okay, I was able to spend more time on the idea and with each new prototype the design has been refined. Since then, six prototypes have been built, each more efficient, more powerful and lighter than the previous one.
In he migrated to Australia where he established a construction engineering company. From his early experience with Wankel rotary engines, Angelo became interested in developing a more efficient engine than the traditional reciprocating internal combustion engine, and he has worked on various alternative concepts intermittently over the last 30 years.
Recognising the potential of his invention Di Pietro decided to fully focus on the development of the new motor concept. The principle worked with the first prototype and, although not built to fine engineering tolerances, its performance far exceeded expectations. Engineair Pty Ltd http: In the first 2 years the company focused on developing prototype models to test the concept and understand the performance characteristics.
Current development status shows performance and efficiency to be superior over state of the art air motor technology. The project will run over enabling CityWide to test the vehicle under different environmental conditions.
Engineair has already successfully tested the powerplant in a roadgoing passenger car, a go-kart, a boat and as the power source for a utility vehicle for use in the Melbourne Fruit and Vegetable market, the latter project in conjunction with the Melbourne Market Authority. 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 into six expansion chambers by pivoting dividers.
These dividers follow the motion of the shaft driver as it rolls around the stator wall. The cylindrical shaft driver, forced by the air pressure on its outer wall, moves eccentrically, thereby driving the motor 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 air film. Timing and duration of the air inlet and exhaust is governed by a slotted timer which is mounted on the output shaft and rotates with the same speed as the motor.
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 at high pressure 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. Motor speed and torque are simply controlled by throttling the amount or pressure of air into the motor. The Di Pietro motor gives instant torque at zero RPM and can be precisely controlled to give soft start and acceleration control.This wooden air locomotive engine is constructed of Baltic birken plywood and one purchased the plans for this locomotive engine from Mathias Wandel's website at.
Powered by a HP Honda 4 Cycle GX engine, the Rol-Air HK18 is an upgraded version to the GX models, enabling it to deliver up to 50% higher CFM by comparison. The powerful engine is equipped with Automatic Engine Idle for improved fuel economy and prolonged service life.
First Air Car. The first air powered vehicles were actually trains. The Mekarski air engine, the Robert Hardie air engine and the Hoadley-Knight pneumatic system were used in . Air compressors can be powered by either an electric motor or a gas engine.
Adding a gas engine to run a compressor gives you the freedom to have compressed air virtually anywhere.
These types of compressors are typically used at construction sites where electricity is not readily available. It is % more efficient than any other air powered engine built to date and its high torque makes it the first air engine suitable for mobile applications.
The . The Modular 1 is a Pin and Ball Valve engine that runs on compressed air. It is based on model air craft engines that used CO2 cartridges for power. Being powered by compressed air there is more power available for less than perfect machining.
