His idea was so brilliant that Texas A&M University became involved in the project, providing MacDowell with technical expertise and a testing environment to aid in the development of the engine. The invention will be more readily understood by reference to the following description taken with the accompanying drawings, in which: In accordance with an embodiment of the invention, a personal vehicle is provided that includes a hybrid Stirling engine/generator to provide power to the vehicle. A lean fuel air mixture has more air than a stoichiometric mixture (i.e., 15.67 grams of air per gram of propane, for example). A personal vehicle for transporting a user over a surface including an external combustion engine. The history of Stirling cycle engines is described in detail in Walker. The marketing success of hybrid vehicles significantly depends on the selection, integration and cost of the energy systems. 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. The analysis of the simulation results can be employed to identify the critical features of the Stirling-powered vehicle. The control system maintains the stability of the personal vehicle by continuously sensing the orientation of the vehicle, determining the corrective action to maintain stability, and commanding the wheel motors to make the corrective action. The air is considered fully warmed up when it exceeds its known ignition temperature. The centerpiece of MacDowells innovationis the Stirling engine, which was created in 1816. A Stirling cycle engine produces both mechanical energy and heat energy appropriate for space heating.

Typically, the combustion engine is an internal combustion engine.

In a preferred embodiment, where the fuel is propane, the start fuel-air ratio is 0.052 grams fuel to gram air, which results in approximately 4% oxygen in the exhaust of the engine. Accordingly, the fuel-air ratio is first controlled by the controller (shown in, A given fuel will only ignite over a limited range of fuel-air ratios.

downsizing engine cylinder four The LBO will increase as the temperature of the incoming air (i.e., the preheated air) increases.
This recycling feature boosts the engines efficiency to a whopping 50 percent. In addition, the personal vehicle includes a controller for controlling a total power load placed on the external combustion engine so as to provide short term regulation of external combustion engine parameters. Stay tuned. The air flow rate may be adjusted, for example, in response to a change in the fuel flow rate or a change in the air preheat temperature. SAE International's core competencies are life-long learning and voluntary consensus standards development. As more air is added to the fuel, the emissions of CO, HC and NOx decrease until the amount of air is large enough that the flame becomes unstable. 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. He also plans to submit his laboratory findings to the Texas Transportation Institute, which will verify his 100 miles per gallon claims. In order to increase the efficiency of heat transfer from exhaust products of the combustion process generated by burner. Typical components of the burner and preheater assemblies, in accordance with embodiments of the present invention, are described with reference to, The overall efficiency of a thermal engine is dependent in part on the efficiency of heat transfer between the combustion gases and the working fluid of the engine.
