Goal
Create a low-cost, lightweight, pollution-free engine with very high fuel efficiency for vehicles and generators.
Problem
Heavy, high-rpm internal-combustion engines that waste >90 % of fuel energy, require complex transmissions, and emit pollutants.
Concept Summary
A radial external-combustion engine that uses a closed-loop gas/steam drive fluid to push pistons via rollers in an eccentric cam groove. The engine runs at 750 rpm, has no crankshaft, and can be attached directly to a drive wheel, delivering power on every piston stroke.
Principles
- external combustion
- radial piston arrangement
- swashplate / cam-groove power transfer
- constant-pressure drive fluid
- direct-drive to wheel
- use of alcohol-water fuel mixture
Scientific Domains
Materials
- alcohol
- water
- perhalogenated benzene
- lubricating oil
- steel
- aluminum
Mechanisms of Action
- Fuel (alcohol-water) burned to generate steam/pressurized gas
- Pressurized gas applied alternately to opposite sides of pistons
- Reciprocating pistons move rollers that ride in an eccentric cam groove on a flywheel
- Continuous torque produced on every stroke, allowing direct wheel attachment
Energy Sources
Applications
- Automobile propulsion
- Truck propulsion
- Boat propulsion
- Portable generator
- Fluid pump
Claimed Performance
Better than 50 mpg (conservative), up to 80 mpg claimed; engine weight 45 lb; 8-cylinder radial layout; 750 rpm; life >150 000 mi; 17 moving parts.
Experimental Evidence
Laboratory dynometer tests reported >50 mpg on a large automobile; inventor's own readouts cited as basis for the claim.
Replication Status
No independent replication reported; rights sold to an Indonesian firm but no production to date.
Limitations
- No verified real-world fuel-economy data
- Requires alcohol-water fuel mixture
- Manufacturing complexity of radial swashplate system
- Lack of commercial production
Red Flags
- Absence of peer-reviewed testing
- Claims based solely on inventor's laboratory readouts
- No independent replication or commercial deployment
