ENGINE PATENTS

Introduction
In 2001 and 2002 International patents of our unique 2 stroke engine design were granted in Australia, New Zealand, Canada and USA. With patents pending in Europe and Japan. We are looking for business partners to assist with this venture.

Background
The aim of this proposal is to develop to market and sell the rights to Patented engine ideas.
This patent is specific to 2 stroke engines. Development to date had concentrated on isolating the optimum configuration using empirical testing, on a variety of engines. Torque and BHP gains from 10% to 40% accross the entire operating range are being measured, without other external modifications other than jetting.

Our configurations enable the engine RPM power capability even more, overcoming the increasing richness of the engine during high RPM operations.

All testing has been done on MX and Enduro bikes.

Engine carburation requirements change greatly showing how large the efficiency increase is.

Dynojet 150	Standard BHP	Modified BHP	Standard Jet	Main Jet	Tested km
'95 KTM 125 SX	25	34	212	160	1,500
'97 KTM 360 EXC	44	59	175	148	7,500
Jaydee 280	42	54	170	145	5,200
'02 Gas Gas 300	39 @8000 rpm	50	-	165	2,500

Modificatios required
Casting ch anges are required to the barrel, crankcases and piston and exhaust pipe repositioning is required. Engine design can be unchanged if you wish.
To best take advantage of the concept the engine must be a reed valve crank case type.

Advantages

More power al all RPM
More RPM
Lower emissions
Higher primary compression ratio
Stronger castings around main bearings
Shorter transfer ports - 30% shorter
Less volume in transfer posts gives quicker cyclinder filling. Transfer port timings can be reduced as they charge quicker.
Smaller engine - barrel can be lowered 10 to 30mm
Peak torque extended by 500 to 1500 RPM depending on engine size and configuration
Inlet reeds can be designed to block rear facing transfer port to give better intake shape and higher intake velocity and crankcase filling
Lighter piston with lower friction drag as pin height is reduced

Disadvantages

Cost to develop
No problems know yet
