Scuderi Split Cycle Engine
Transcript of Scuderi Split Cycle Engine
Chris Deloyer Scuderi Split-Cycle Engine History
How Scuderi Engine Works
Conclusion and Questions Outline 1860 First 4-stroke engine produced in quantity 2002 Scuderi Engine Group started 2009 Prototype of split cycle engine demonstrated Carmelo Scuderi filed first patent for split-cycle engine
Claimed to be biggest advancement in internal combustion engines in 130 years 2001 So, let's see how the Scuderi Engine works... 2010 Testing and licensing History Compression piston Power piston Air tank Crossover passage Exhaust 4 valves for every cycle 1862 Nikolaus Otto first to sell the 4-stroke engine 1885 Supercharger invented 1900 Diesel Engine demonstrated 1916 Turbocharger invented scuderigroup.com Advantages Power delivered every revolution
Able to boost engine pressure to 2.5 bar (conventional engine is 1.5 bar) before auto-ignition due to crossover passage cooling
Torque delivered is equivalent to diesel engine due to increased boost pressure (70% increase)
Highly knock resistant due to firing after TDC
From 51% to 150% increase in Specific Power Increase [kW/Liter] dependent on boost pressure and RPM
Ability to easily integrate an air hybrid system
Fuel mileage increase up to 54%
Reduce NOx emissions up to 85% Normal Mode
High Efficiency Mode
Cruising Mode Air Hybrid System Modes of Operation Key Advantages Low cost and weight
Air tank and controls
High power density
Efficiently converts kinetic energy into compressed air energy
High speed charge and discharge of energy Conclusion Split cycle engine divides compression and power stroke
Greatly increases power, torque, and efficiency
Simple air hybrid system
