The Scuderi Split-Cycle Engine solves both the breathing and thermal efficiency problems with two unique and patented concepts.
On the compression side of the Scuderi Engine the breathing problem is solved by reducing the clearance volume between the piston and the cylinder head to less than 1 mm. This design requires the use of outwardly opening valves that enable the piston to move very close to the cylinder head without the interference of the valves. This effectively pushes almost 100% of the compressed air from the compression cylinder into the crossover passage eliminating the breathing problems associated with previous split-cycle engines.
The revolutionary feature of the Scuderi Engine is combining a Split-Cycle design with the combustion process of firing ATDC. This combination is what produces a truly unique thermal dynamic process that enables new levels to be reached for both efficiency and power. Its design is elegantly simple leading to further enhancements that will continue to improve the engines performance.
The current NA prototype engine demonstrates the viability of the design. It proves that concept of splitting the cycles and firing ATDC is real and it is just the start of many design improvements to come.
