Initiation 2005

Invention improvements to wankel rotary engines

Patent application submitted, international application number PCT/IL2006/00091 publication date 15/02/2007

Seeking strategic partnerships and investment

PROJECT OVERVIEW 3. P#03 Drawbacks of Prior Art Wankel System 4. The Concept P#04 5. P#19 Advantages ofROTEC 6.

Higher efficiency (lower fuel consumption)

Highly improved power to weight ratio in

High level of altitude compensation and noise reduction

Higher torque availability and smoother operationthroughouta widerrange of engine RPM

Unthrottled, heavy fuel C.I. Engine similar to S.I. Engine inrpm, power to weight ratio and output power

During-operation, variable compression-ratio, turbocharging, fully scavenged combustion chamber and expansion volumecharacteristics

High reliability, long TBO (time between overhauls) similar orbetter than a piston engines

Rotec main advantages VS. Prior art Wankel and piston engines 7. Market Needs

Key factors across all type engines:

Performance

Reliability

Durability

Emission levels

Cost

Fuel consumption and efficiency

8.

Marine propulsion: Boats&yachts

Aviation: Unmanned Aerial Vehicles (UAVs )

light Aviation

Land propulsion

Stationary : Generators & pumps

Potential Applications 9. Rotec Target Market potential

Primary target market:

Unmanned Aerial Vehicles (UAVs)

Key Determining factors:

High power density

high efficiency

cost effectiveness

Cleantech compatible

10. CleanTech Compatible

Adaptable to most existing fuels including green fuels

Perfect combustion

Over expanded, fully controlled, combustion process.

low Emission levels

High efficiency

Very low noise level

11. Business Model

R&D Company business model

Licensing (manufacturing & research)

Consulting & joint research

Design of customized applications for manufacturers

R&D with industrial and academic parties

It is not unlikely that rotec will become an acquisition target sooner due to its critical position

12. Risks & Concerns

Engine market - highly competitive and takes long time to successfully penetrate

Long decision and highly bureaucratic process

High R&D costs(even largest firms combine efforts on R&D)

Conservative approach by key players on R&D investments strategy

Manufacturers tend to do in house R&D or partner with other established manufactures
