Goal
Increase vehicle fuel mileage and reduce exhaust pollution.
Problem
Low fuel efficiency and high emissions from internal combustion engines.
Concept Summary
A pressure-controlled carburetor and fuel-air ratio regulator that improves the mixing of fuel and air, delivering a richer mixture for better combustion efficiency and lower emissions.
Principles
- Pressure regulation
- Fuel-air mixture control
- Fluid dynamics
Scientific Domains
Materials
- steel
- aluminum
- rubber
Mechanisms of Action
- Regulates fuel flow using engine vacuum/pressure
- Maintains optimal air-fuel ratio for combustion
- Improves atomization of fuel
Applications
- Automotive fuel delivery
- Vehicle emissions reduction
Claimed Performance
Mileage increased by 25 % and pollution reduced by 45 % when installed on a fleet of Yellow Cab vehicles.
Experimental Evidence
The inventor modified every carburetor in the local Yellow Cab fleet shortly after his arrival there, reporting a 25 % mileage gain and a 45 % reduction in pollution.
Limitations
- Requires retrofit of existing carburetors
- May not be compatible with modern fuel-injection engines
