What is NPS?
What is NPS about?
How NPS works compared to standard and race engines
Operating Principles of NPS
Basic description of parts and processes that work together to produce NPS
Combination of parts and processes that work together to produce NPS
HTCSI combustion compared to HCCI combustion
Working prototype engines
Negative pressure produces the SAME force as positive pressure
Vacuum or boost is the result of high pressure forcing itself into low pressure environment
How internal combustion engines and superchargers actually work

Combination of parts and processes that work together to produce Negative Pressure Supercharging

The basic combination of parts and processes needed to produce and control Negative Pressure Supercharging are...

High Velocity Tri-Y Headers
Synchronised Valve Timing
Special Profile Camshaft
Special Ignition Timing
Cold Spark Plugs

...but it�s the combination of parts and processes shown below that allow Negative Pressure Supercharging to work at optimum



Negative Pressure Supercharging
 
 

NPS is produced by...

High Velocity Tri-Y Headers
NEW compact small pipe
                high velocity Tri-Y
                megaphone headers.

Special Profile Camshaft
NEW high lift intake, low lift exhaust profiles
                applied to conventional
                flat-tappet camshaft.

 
 
 

NPS is controlled by...

Special Ignition Timing
NEW ignition advance curve with less advance.

Modified Cylinder Heads
NEW specs and features applied to conventional cylinder heads.

Cold Cooling System
NEW cooling system
uses low flow and
                conventional parts.

Cold Spark Plugs
Conventional spark plugs with cold heat range.

 
 
 

NPS is produced and controlled by...

Synchronised Valve Timing
NEW synchronised valve timing process
                 with early closing
                 intake and exhaust
                 valves.

NOTE
Negative Pressure Supercharging is controlled mechanically therefore it does NOT need computers but they may be used to enhance the NPS process.

 
 
 

NPS is enhanced by...

Hot Air Induction
NEW hot air and cold water system produces ultra fast burn.

Ultra Fast Burn
NEW HTCSI combustion produced by a combination of NPS, HPDT
              and HAI processes.

Spark Amplifiers
NEW plasma spark technology improves ultra fast burn.

 

NPS uses 7 highly advanced processes

•  NPS - Negative Pressure Supercharging
•  CHVEG - Compressed High Velocity Exhaust
    Gas
•  SVT - Synchronised Valve Timing
•  HPDT - High Pressure Differential Turbulence
•  UHV - Ultra High Vacuum
•  HAI - Hot Air Induction
•  HTCSI - Homogenous Thermal Charge Spark
    Ignition combustion

NOTE
Today's mechanically complex wonder engines do NOT use any of these highly advanced processes.
