Constant Volume Combustion
The following theoretical study on Constant Volume Combustion was conducted in 2010-11 and while the author was unaware of any engine configuration to achieve the results, it’s almost as if it was written to further incentivize the development of the Rotodyne Engine.
Rotodyne Engine’s Pioneering Patent Claim for Constant Volume Combustion
US Patent 7,677,210 – the pioneering patent on the discovery of piston dwell within a barrel type ICE.
SwRI Assessment Report
The Southwest Research Institute’s evaluation of the Rotodyne Engine lays out the merits of the engine as well as the engineering challenges.
Case Studies
Computational Fluid Dynamics (CFD) modeling of the combustion process with 3 different piston dwell scenarios.
Computational Piston Motion Spreadsheet
This proprietary computational spreadsheet visualizes adjustments to the design parameters in a dynamic graph of the piston motion vs. crank angle. There are 16 variables that are modelled in this spreadsheet including the angle of advancement or retardation between the Torque Plate and the Cylinder Carriage, the offset of the Torque Plate center with respect to the center of the Cylinder Carriage, the tilt of the Torque Plate with respect to the Cylinder Carriage, and the pitch and yaw of the Cylinder axis.
Solidworks Model
Rotodyne Engines will also make available the entire Solidworks virtual model of the engine to its partners to facilitate the production of the prototype(s) which includes the following parts:

Rotodyne Engine Development, LLC is now executing a distributed engine development strategy to partner with independent engine builder(s) to build and test a prototype of the revolutionary Rotodyne Engine, in order to then sell and/or license the technology under US Patent 7,677,210, which is the pioneering patent for constant volume combustion. All engine builder participants will receive a share of the profits and proceeds from all sales and licensing.
The Rotodyne Engine is set to disrupt the $500B standby generator market. It is the first and most practical multi-cylinder engine to employ the textbook constant volume combustion cycle. Other markets and applications worldwide provide further incentive.
