Technosearch Rotary Engine
For many years, changes to internal combustion engines driven by competition, lowering manufacturing cost, consumer requirements, governmental regulation and environmental pressures have been incremental.
Technosearch considers its rotary engine represents a technological step change over the most advanced combustion engines of today.
It believes is considered the engine is compelling because:
- The car maker using it will have much lower manufacturing costs, while offering vehicles uniquely differentiated from competitors by their power plants
- Consumers will have lower acquisition and running costs, and
- Its minute emissions footprint will be approved of by politicians, regulators and the public attempting to deal with cutting environmental negatives while maintaining public vehicle mobility.
An independent review of the original engine, headed by an expert from the School of Mechanical and Industrial Engineering at the University of NSW concluded the Technosearch rotary engine, “is both sound and viable”, and, “further development of the device appears to be warranted.”
Technosearch considers that through further developments, protected under patent, it has satisfactorily addressed suggestions for improvement made by the review team.

Key Features
Size
A conventional 4 cylinder engine has overall length of approximately 55 cm, height of approximately 75cm and a perimeter approximately 200cm.
The Technosearch rotary engine with comparable performance to that conventional 6 cylinder engine has an overall length of approximately 40cms, height of approximately 25cm and perimeter of 75cm.
Weight
Compared to conventional 4 cylinder 4 stroke engines that weigh nearly 120kg, the Technosearch engine of 1 litre capacity weighs approximately 35kg. A 6 cylinder conventional engine weighs around 200kg. The Technosearch engine of comparable capacity will weigh around 44kg.
Simplicity of design
The Technosearch engine has only 6 moving internal parts. This contrasts with at least 14 moving parts in a 4 cylinder piston engine. The reduction in moving parts reduces manufacturing costs, both for component casting and unit assembly. It will also reduce maintenance costs and reliability of operation.
Simplicity of assembly
The reduced number of moving parts, combined with lower weight of the fully assembled engine will reduce assembly costs. While a contributing factor in reduced manufacture and maintenance costs is already noted, the cost of plant required to build the Technosearch engine will be significantly less than that for alternative engines.
Power
A 500cc Technosearch engine will produce the same power and torque as a conventional 6 cylinder piston engine.
Increasing power of the Technosearch engine requires only the addition of a piston blade to the drive shaft, whereas a conventional engine must be bigger, and/or turbo-charged or super-charged. Available calculations demonstrate that the 3 blade Technosearch engine is equivalent to a 6 cylinder conventional engine and a 4 blade Technosearch engine is equivalent to an 8 cylinder engine.
Flexibility of application
The Technosearch engine is extremely flexible with operating efficiency maintained with all known slow or fast burning fuels, and a rev range (500 – 16,000) wide enough to accommodate a variety of uses, from lawn mowers to light aircraft. In addition, the volume, weight and operational simplicity of the Technosearch engine make it ideal for adaptation to a hybrid liquid fuel/electric motor vehicle.
Environmentally friendly
Testing of the original Technosearch engine without special modification demonstrated 40% greater fuel efficiency and 50% reduction in emissions of unburnt fuel when compared with piston engines of the time. Both engines were operated without catalytic conversion of exhaust gases. A new petrol car today produces around 1/20th of the emissions of an older car not fitted with a catalytic converter.
Because the combustion and exhaust processes of the Technosearch engine increase efficiency of fuel combustion, it will result in significantly greater reductions in exhaust outputs when compared with current petrol internal combustion engines.
Combustion in the engine shuts down when the vehicle is stopped or coasting.
