The marketing success of hybrid vehicles significantly depends on the selection, integration and cost of the energy systems. a drive motor coupled to the energy storage device and the assembly, the drive motor powered entirely by the locomotive power provided by the energy storage device; and. This document is focused in the application of Stirling engines as the power source for automobile propulsion. The marketing success of hybrid vehicles significantly depends on the selection, integration and cost of the energy systems. The air is considered fully warmed up when it exceeds its known ignition temperature. The response time of an internal combustion engine, on the other hand, is very short because the combustion gas is the working fluid and can be directly controlled by the fuel flow rate. [2] The simulation tool allows the study of Stirling-powered vehicles in conventional or hybrid electric (series, parallel or split) configurations, determining parameters of the vehicle like fuel consumption, power output, emissions, energy flow and the engine's temperature profile. d. a controller, coupled to the drive arrangement, for controlling a total electrical power load placed on the external combustion engine such that short term regulation of external combustion engine temperature is provided. Once the flame is stabilized, and the temperature of the combustion chamber of the burner reaches the desired warmup temperature, the fuel-air ratio is then controlled based on the air preheat temperature and the fuel type. The hybrid Stirling engine/generator is advantageously of a small size (5 kW or less) with ultra low emissions and may be implemented in a variety of personal vehicles. In accordance with an embodiment of the invention, a personal vehicle for transporting a user over a surface includes a support for supporting the user, a ground contacting module having at least one ground contacting member and a drive arrangement for causing locomotion of the support, ground contacting module and user over a surface.

At this point, pockets of the fuel-air mixture will pass through the burner without complete combustion. He also plans to submit his laboratory findings to the Texas Transportation Institute, which will verify his 100 miles per gallon claims. In yet another embodiment, the personal vehicle has modes in which it is not statically stable. In order to optimize this process, a simulation tool for Stirling vehicle was developed based in ADVISOR, a proven hybrid electric vehicle simulation software, and MARWEISS, a Stirling engine simulator.

NEW POWER CONCEPTS LLC, NEW HAMPSHIRE, Free format text: The vehicle includes a generator for converting the mechanical energy produced by the external combustion engine to electrical energy and an energy storage device for storing power provided by the generator and for providing power to the external combustion engine and the assembly. The internal combustion engine, dominant of the vehicle market, has been the option of choice for auxiliary power unit of the hybrid vehicle, although other power sources as fuel cells, Stirling engines and gas turbines have been employed as well [1]. The foregoing references are hereby incorporated by reference in their entirety. In his model, the Stirling engine runs at a fixed RPM generating electricity that is used to charge the batteries, which drive motors that propel the vehicle. The response time of a Stirling cycle engine is limited by the heat transfer rates between the external combustion gases and the internal working fluid of the engine and may be on the order of 30 seconds.
