1. Modified 4-stroke Engine
Extremely Clean and Fuel-efficient

2. Problems of State-of-Art Engines
Low efficiency
High pollution
*********************************************
A hybrid car’s engine is the same inefficient
A hybrid car with efficient engine is efficient
Cylinder decavitation does not add to efficiency
SISS does not increase engine efficiency either
HCCI is 15% more efficient but hard to control

3. Surcharging and Supraignition
At BDC piston position
Retained warm exhaust gas let to mix with and pre-compress the intake air or air-fuel mixture
Valve operated just as intake and exhaust
Needs no other control
A pressure accumulator
Supraignition
At TDC piston position
Retained hot exhaust gas is let to mix with and ignite the compressed air-fuel mixture
Valve operated just as intake and exhaust
Needs no other control
A heat accumulator

4. Animated 4-cylinder Engine Operation

5. Animated 1-cylinder Engine Operation

6. Basic Configurations Surcharging from buffer
Surcharging from another cylinder
Supraignition from buffer
***********************************
Fuel injection at surcharging
Fuel injection at supraignition
Direct injection into buffer

7. Major Advantages 25-75% fuel savings, doubles the mileage or the range
% reduction in NOx, SO, CO, PM and toxic emissions
25-75% less CO2, greenhouse gas emission at cooler temperature
100% more burning cycles in repetition of diminishing volumes
15-55% internal exhaust gas recirculation (IEGR)
15-45% reduction in peak temperature and peak and average pressure
10-20% increase in volumetric efficiency
Plus more power or torque, less noise and less maintenance and more
Simplicity (just add some manifolds, valves or portholes)
Quick market introduction and penetration is feasible
No major technology change (employs common techniques)
Reduces demand on electronic controls (automatic, needs no control)
Saves the catalytic converter or afterburner or oxidizer
Complies with tough worldwide emission control regulations

12. Simple as is…! In summary:
The 50% fuel savings and 99% emission reduction are attractive to manufacturers, dealers, consumers, environmental activists and regulatory agencies.
Both gasoline and diesel engines can be modified with increase in torque and no loss in power or vice versa.
The engine modification has marginal effect on the engine weight, volume and cost (+/- 5%).
Engine retrofitting is feasible and practical.
No new technique or technology is required.
Market introduction can be swift and decisive.
Licensee can expect great extra profit (25-75x ROI).
