The technology

A breakthrough in drive technology

This drive system combines efficiency with size and environmental friendliness and offers outstanding performance for a more sustainable future and climate change.

The engine uses advanced mechanical dynamics in which the piston performs work in both directions using air pressure.

One revolution achieves two power strokes.

This is four times more than today’s four-stroke engine.

Mechanical or electronic valves release the air pressure for the work of the straight piston movement. The crank drive converts the straight piston movement into a rotary movement. Many different crank drives can be used!

The air motor operates at a low speed level, which results in low-vibration and quiet operation.

The engine can dispense with numerous components:
Cylinder head control, exhaust filter, ignition system, cardan shaft and more.

The drivetrain may have simpler components:
Transmission, differential, cardan shaft, all-wheel drive and more.

Efficiency is increased.

A differently controllable operating pressure in different cylinders reduces air consumption. The efficiency increases.

The PME air motor offers immediate power in the low speed range.

This enables freewheeling in the drive.

Motor and crank drive variants

More or fewer cylinders per crank drive are possible.

Less large or several small cylinders are possible.

All types of crank drives are possible.

A crank drive with a straight piston guide is advantageous.

Compressed air tank

Basis for increased flexibility, safety and cost efficiency in vehicle design.

The tank can replace the chassis or the floor assembly. This makes it easier to build many body variants.

Result: Cost savings

The tank also serves as a buffer zone in the event of an accident, which increases the level of safety.

The compressed air tanks can be positioned flexibly in the vehicle.

Design freedom and integration in the vehicle is simplified.

A motor is attached to each wheel on the torsionally rigid tank.

Simplification of the all-wheel drive.

You can fill up with air at any socket using the small on-board compressor or at compressed air stations at filling stations.

Simple operation

The motor only runs when drive power is required.

This saves energy and reduces wear.

Power is available immediately when the accelerator pedal is pressed.

Responsive and satisfying driving is possible.

The accelerator pedal controls the air pressure on the intake valves to precisely regulate the desired power.

If no power is required, the vehicle continues to freewheel.

The engine stops and efficiency increases.

The freewheel can be switched on or off automatically depending on the riding situation.

If it is switched off, recuperation is enabled. Energy is recovered during braking. The efficiency increases.

Environmental and climate aspects

Air is used, but not polluted

Drive with air – protect the environment
The PME compressed air motor uses the most environmentally friendly and sustainable “fuel” in the world – air.

Our breathing air is simply compressed and expanded again.

It is the most sustainable alternative to all previous drives.

The smallest ecological footprint, a sustainable future and numerous environmental benefits are secured.

Air as a working medium is available in unlimited quantities and does not require the depletion of our planet’s natural resources.
In contrast to current solutions such as lithium-ion batteries or crude oil.

The production of air as a fuel does not generate any hazardous waste, harmful by-products or climate pollution anywhere in the world.

No exhaust emissions are produced when compressed and then expanded air is used.

The air is released back into the atmosphere unchanged and free of pollutants.

No air pollution from carbon dioxide or nitrogen oxides, no soil contamination or risk to groundwater and wastewater.

The extraction, transportation and production of compressed air as a fuel require minimal energy and therefore have virtually no harmful impact on the environment.

Using electricity from renewable energy sources or electricity from particle fusion to generate compressed air produces a very cost-effective and CO2-neutral fuel.

The compressed air motor minimizes the high consumption of energy, raw materials and water and avoids the use of rare earths.

The impact on agricultural land and habitats and the enormous global transport costs are eliminated.

There are no harmful emissions and no risk of damage to health.

Revolutionize the mobility of tomorrow with thePME air motor

The PME air motor is a groundbreaking innovation.

It outperforms today’s drive systems in terms of efficiency, safety and environmental compatibility.

The design has fewer components, manufacturing costs and service costs are reduced.

Water cooling, oil lubrication and rare earths are no longer required. A clean and reliable solution.

This compact, versatile and simple motor is revolutionizing the drive of vehicles and industrial applications.

The PME compressed air motor opens up the futureCO2 climate protection with the best carbon footprint of all drives.

With the smallest footprint of all drive systems, the
PME air motor is at the forefront of environmentally friendly technologies.

Operation without oil lubrication, sparks and fire.
Ideal for sensitive applications, e.g. in bodies of water, indoor areas or potentially explosive atmospheres, etc.

The explosion-proof and incombustible air propellant offers maximum safety.

The low number of individual parts without complicated production and low maintenance significantly reduce the total cost of ownership.

Ideal for a wide range of vehicle types and applications, including specialized industrial machinery.

The principle can also be used for pumps, steam and hydraulic motors and compressors, as well as brakes.
